The Decision That Costs or Saves You Hundreds of Thousands
You found the perfect house. The price is right. Your offer got accepted. Now comes the paperwork mountain, and buried in those documents sits one question that will define your financial life for decades: 15-year or 30-year mortgage?
The mortgage officer rattles off numbers. Monthly payments, interest rates, total interest paid. Your head spins. The 15-year payment feels uncomfortably high. The 30-year payment seems manageable but the total interest paid over three decades looks obscene. How do you choose between financial stress now versus financial waste over time?
This decision affects more than just your housing costs. It determines how much discretionary income you have monthly. It influences your ability to save for retirement, fund your kids’ education, or handle emergencies. It shapes your net worth growth over your working years. Getting this choice right or wrong creates financial differences measured in hundreds of thousands of dollars.
Most people default to 30-year mortgages because monthly payments fit budgets more easily. They never run the real numbers comparing both options comprehensively. They don’t understand the hidden costs and benefits beyond simple monthly payment calculations.
Understanding the Fundamental Differences
Before analyzing which option suits your situation, understanding exactly how these mortgages differ helps you evaluate them properly.
How 15-Year Mortgages Work
Fifteen-year mortgages require paying off your entire loan in 180 monthly payments. Lenders divide your principal and interest across these 180 payments, resulting in significantly higher monthly amounts than 30-year loans.
Interest rates on 15-year mortgages typically run 0.25 to 0.75 percentage points lower than 30-year rates. A bank quoting 6.5 percent for a 30-year mortgage might offer 5.75 to 6 percent for a 15-year loan. This rate advantage reduces your total interest costs substantially.
Principal paydown happens much faster with 15-year loans. Your first payment allocates more money toward principal and less toward interest compared to 30-year loans. This builds equity rapidly and accelerates your path to full ownership.
Loan payoff occurs by definition in exactly fifteen years assuming you make all scheduled payments. Your final payment comes in year 15, after which you own your home free and clear. This timing lands many homeowners in their 40s or early 50s mortgage-free if they bought in their late 20s or 30s.
How 30-Year Mortgages Work
Thirty-year mortgages spread payments across 360 months—double the time of 15-year loans. This extended timeline creates much lower monthly payment requirements that fit more household budgets comfortably.
Higher interest rates apply to 30-year mortgages reflecting the extended time lenders wait for repayment. That quarter to three-quarter point rate difference seems small but compounds dramatically over thirty years.
Principal paydown moves at a glacial pace initially. Your first several years of payments go almost entirely to interest with minimal principal reduction. A $300,000 loan at 6.5 percent interest only pays down about $30,000 in principal during the first five years while paying $95,000 in interest.
Flexibility exists to pay extra toward principal whenever you want. Nothing prevents making additional payments reducing your balance faster. However, statistics show most people never make extra payments despite good intentions. Life expenses absorb available cash.
The Interest Cost Difference in Real Numbers
Numbers speak louder than theory. Here’s how a $300,000 loan compares across both terms:
30-Year Mortgage at 6.5% Interest:
- Monthly payment: $1,896
- Total paid over life of loan: $682,632
- Total interest paid: $382,632
15-Year Mortgage at 6% Interest:
- Monthly payment: $2,532
- Total paid over life of loan: $455,760
- Total interest paid: $155,760
The 15-year loan costs $636 more monthly but saves $226,872 in interest over the loan’s life. That quarter-million-dollar difference represents the true cost of choosing the 30-year option.
When 15-Year Mortgages Make Perfect Sense
Certain financial situations and personal circumstances make 15-year mortgages clearly superior choices despite higher monthly payments.
High Income with Low Debt
If you earn $150,000 or more annually with minimal other debt obligations, the higher 15-year payment rarely strains your budget meaningfully. The $600 to $800 monthly difference between a 15-year and 30-year payment represents just 5 to 7 percent of your gross income.
High earners benefit more from interest savings than low earners benefit from payment flexibility. Someone earning $50,000 needs every dollar of monthly cash flow flexibility. Someone earning $180,000 has discretionary income to allocate toward aggressive mortgage payoff.
Consider a family earning $200,000 annually. A $2,500 monthly mortgage payment instead of $1,900 still leaves substantial income for other goals. The interest savings over fifteen years likely exceeds what they’d accumulate investing the payment difference given average investor behavior.
Approaching Retirement Age
Homebuyers in their 40s and 50s should strongly consider 15-year mortgages to ensure mortgage-free retirement. Entering retirement with mortgage payments drains fixed incomes rapidly.
A 45-year-old choosing a 30-year mortgage faces payments until age 75. A 50-year-old carries mortgage debt until 80. Fixed retirement incomes rarely stretch comfortably across mortgage payments, property taxes, insurance, healthcare, and living expenses.
The same 45-year-old choosing a 15-year mortgage owns their home free and clear at 60—five years before typical retirement. This creates flexibility to retire earlier or enjoy retirement income without housing debt.
Retirees without mortgage payments need significantly less income than those with payments. A couple requiring $6,000 monthly with a $2,000 mortgage payment only needs $4,000 monthly without the mortgage. This reduces required retirement savings by hundreds of thousands of dollars.
Strong Financial Discipline and Conservative Temperament
Some people psychologically handle debt poorly. Carrying long-term debt creates stress regardless of interest rates or investment alternatives. For these individuals, the peace of mind from faster payoff justifies higher payments.
Financially conservative people often prefer guaranteed savings from interest reduction over theoretical gains from investing payment differences. The interest savings from a 15-year mortgage are guaranteed. Investment returns are not.
People with track records of lifestyle inflation shouldn’t count on investing 30-year payment differences. If every raise historically led to increased spending rather than increased saving, the flexibility of a 30-year mortgage likely disappears into consumption rather than building wealth elsewhere.
Professional Stability and Career Security
Government employees, tenured professors, established physicians, or others in secure careers can comfortably commit to higher payments. Income stability over fifteen years seems virtually certain.
The higher payment becomes problematic only if income drops unexpectedly. Careers with strong job security eliminate most of this risk. Recessions might freeze raises but rarely eliminate positions for tenured or highly credentialed professionals.
Dual-income households with both spouses in stable careers can handle aggressive mortgages even more safely. If one income temporarily disappears, the other covers necessities until employment resumes.
Substantial Emergency Funds Already Established
The higher 15-year payment works best when you’ve already built significant emergency savings. Financial advisors generally recommend three to six months of expenses in accessible savings before aggressively paying down mortgages.
With $30,000 to $50,000 in liquid emergency savings, temporary income disruptions don’t threaten your ability to make mortgage payments. You can cover payments from savings while resolving employment issues without facing foreclosure risk.
Without emergency funds, the payment flexibility of a 30-year mortgage provides safety. You can always pay extra on a 30-year mortgage when finances allow. You cannot lower 15-year payments when money gets tight.
When 30-Year Mortgages Make More Sense
Many financial situations favor 30-year mortgages despite their higher total cost. Understanding when flexibility outweighs interest savings prevents costly mistakes.
Tight Monthly Cash Flow
Families stretching to afford homes need every dollar of monthly cash flow. The difference between a $1,900 and $2,500 monthly payment might represent daycare costs, car payments, student loans, or food budgets.
Housing payments should not exceed 28 percent of gross income according to traditional lending standards. If a 15-year payment pushes you above this threshold, you’re overextending financially. The 30-year option keeps housing costs proportional to income.
First-time homebuyers often face tight budgets. Down payments deplete savings. Moving costs, furniture, repairs, and unexpected homeownership expenses all hit simultaneously. Lower 30-year payments provide breathing room during this adjustment period.
Consider a couple earning $90,000 combined. A $2,500 15-year payment takes 33 percent of gross income before taxes. This leaves minimal flexibility for other obligations and goals. A $1,900 30-year payment at 25 percent of income feels much more manageable.
Young Buyers with Rising Income Expectations
Twenty-somethings and early-thirties homebuyers typically earn less now than they will in ten to fifteen years. Career progression, raises, and job changes normally increase incomes substantially over time.
Starting with a 30-year mortgage allows affordable payments on current income. As income grows, you can make extra principal payments accelerating payoff. This creates flexibility low-income young buyers need without committing to high payments they might struggle to afford initially.
A 28-year-old earning $55,000 might struggle with a $2,400 15-year payment. The same person earning $95,000 at age 38 easily handles extra principal payments on their 30-year mortgage—achieving similar results without the risk of unaffordable early payments.
Income growth isn’t guaranteed. Economic recessions, industry changes, or personal circumstances can flatten earnings unexpectedly. The lower initial commitment of a 30-year mortgage protects against these possibilities while preserving the option to prepay as income allows.
Significant Other High-Interest Debt
Prioritizing credit card debt at 18 to 24 percent interest over extra mortgage payments at 6 to 7 percent interest makes mathematical sense. The interest differential means attacking high-interest debt first maximizes your financial progress.
A family carrying $30,000 in credit card debt benefits more from aggressive credit card payoff than choosing a 15-year mortgage. Pay off the high-interest debt first with the cash flow difference between a 15 and 30-year payment. Later, apply that same monthly amount to accelerating the mortgage payoff.
Student loans at 7 percent or higher might also deserve priority over mortgage acceleration. Federal student loans offer income-driven repayment plans and potential forgiveness that mortgages don’t provide. Balance the interest rates, tax implications, and flexibility features when prioritizing debt payoff.
Strong Investment Discipline and Knowledge
Sophisticated investors with proven track records of consistent investing might benefit more from 30-year mortgages than 15-year options. The payment difference invested and compounded over thirty years potentially exceeds interest savings.
This strategy requires genuine discipline. The $600 monthly difference between a 15 and 30-year payment must actually get invested every single month for decades. Most people have good intentions but poor execution.
Historical stock market returns of 9 to 10 percent annually exceed 6 to 7 percent mortgage interest rates. Mathematically, investing payment differences at 9 percent grows wealth faster than saving 6 percent interest through faster payoff. Reality introduces taxes, behavioral mistakes, and sequence of returns risk that complicate this math.
Tax implications matter. Mortgage interest remains tax-deductible for many homeowners. Investment gains face capital gains taxes when sold. The spread between mortgage interest rates and investment returns narrows after accounting for taxes.
Job Income Variability or Self-Employment
Commission-based sales jobs, seasonal work, or self-employment create income variability that makes high fixed payments risky. Good months might bring $12,000 while slow months bring $4,000.
Lower 30-year payments protect against income swings. You comfortably make $1,900 payments during slow months and prepay extra during good months. A $2,500 15-year payment might be impossible during several consecutive slow months.
Self-employed individuals face additional challenges. Banks scrutinize self-employment income heavily during mortgage applications. Qualifying for a 15-year payment might require higher income documentation than necessary for a 30-year loan.
Business owners might need cash reserves for business opportunities rather than locked into home equity. A 30-year mortgage preserves business liquidity. That liquidity might generate returns exceeding the interest savings from a 15-year payoff.
The Hidden Costs and Benefits Beyond Interest
Monthly payments and total interest tell important but incomplete stories. Several factors beyond simple interest calculations affect which mortgage term suits your situation.
Opportunity Cost of Locked Capital
Equity built in your home through aggressive 15-year payments sits illiquid and inaccessible except through borrowing or selling. That capital cannot be easily redirected to other opportunities or needs.
A family choosing a 15-year mortgage might build $150,000 in additional equity over seven years compared to a 30-year mortgage. However, they also have $150,000 less in accessible savings, retirement accounts, or other investments during those years.
If a major opportunity emerges—starting a business, helping a child, weathering an extended job loss—home equity requires home equity loans or lines of credit to access. These tools cost money and time to establish. Cash in savings accounts or investment accounts provides immediate access.
Balanced approaches might work better than extremes. Choose a 30-year mortgage but consistently prepay extra principal. This builds equity almost as fast as a 15-year loan while preserving the option to skip extra payments during financial stress.
Tax Deduction Considerations
Mortgage interest remains tax-deductible for many homeowners, though the 2017 tax law changes reduced this benefit for numerous filers. The standard deduction increased dramatically, meaning fewer people itemize deductions enough to benefit from mortgage interest deductibility.
For those who do itemize, the after-tax cost of mortgage interest is lower than the stated rate. Someone in the 24 percent tax bracket with 6.5 percent mortgage interest effectively pays about 4.9 percent after accounting for tax deductions.
Fifteen-year mortgages pay less total interest, which means smaller tax deductions over the loan’s life. Thirty-year mortgages generate more interest payments, creating larger deductions. This partially offsets the raw interest cost difference between terms.
High earners in expensive housing markets benefit more from mortgage interest deductions than middle-income earners in modest homes. A $600,000 mortgage generates meaningful deductible interest. A $150,000 mortgage generates minimal deductible interest given today’s standard deduction levels.
Impact on Retirement Savings
The $600 monthly difference between a 15-year and 30-year payment equals $7,200 annually. Invested in tax-advantaged retirement accounts over thirty years, this compounds into substantial wealth.
A 30-year-old choosing a 30-year mortgage over a 15-year option might invest the payment difference in a 401(k). At 7 percent annual returns, $600 monthly for thirty years grows to approximately $740,000. This exceeds the interest savings from a 15-year mortgage on most loan amounts.
However, this calculation assumes perfect discipline investing the payment difference every month for thirty years. Studies show most people don’t maintain this discipline. Money not committed to fixed obligations tends to get spent rather than saved.
Employer 401(k) matches complicate calculations. Contributing enough to capture full employer matches should take priority over extra mortgage payments. The guaranteed 50 to 100 percent return from employer matches exceeds any mortgage payoff strategy.
Inflation Eroding Future Payment Burden
Fixed mortgage payments stay constant while inflation reduces their real cost over time. A $2,000 monthly payment feels different when you earn $60,000 annually versus $100,000 annually years later.
Thirty-year mortgages benefit more from inflation than 15-year mortgages. The fixed payment in year twenty-five costs far less in real terms than in year one. Fifteen-year mortgages get paid off before significant inflation erosion occurs.
Historical inflation averages 2 to 3 percent annually. Your income likely rises at similar or faster rates over time through raises and career progression. This means your mortgage payment consumes less of your income as years pass—but only if you commit to a thirty-year term.
A couple earning $80,000 in 2025 might earn $120,000 by 2035 through normal career progression and inflation adjustments. Their $2,000 mortgage payment drops from 30 percent to 20 percent of gross income despite no change in payment amount.
Forced Savings and Discipline Benefits
Some people need forced savings mechanisms because voluntary saving fails. A 15-year mortgage forces rapid equity accumulation through required payments. This serves as forced savings for people who otherwise wouldn’t save aggressively.
The psychological benefit of forced savings shouldn’t be dismissed. Voluntarily sending extra money to your mortgage each month requires active decision-making. Required payments happen automatically. Behavioral finance research consistently shows people save more through automatic mechanisms than voluntary choices.
However, forced savings in home equity provides less flexibility than voluntary retirement account contributions. You can access 401(k) money through loans or hardship withdrawals despite penalties. Home equity requires refinancing, home equity loans, or selling—all more complicated than retirement account access.
Running Your Personal Numbers
Generic advice fails because individual situations vary dramatically. Running calculations specific to your circumstances reveals which option truly benefits you financially.
The Payment Difference Calculator
Start with your proposed loan amount. Let’s use $350,000 as an example.
30-Year Mortgage:
- Loan amount: $350,000
- Interest rate: 6.5%
- Monthly payment: $2,212
- Total interest paid: $446,320
15-Year Mortgage:
- Loan amount: $350,000
- Interest rate: 6%
- Monthly payment: $2,954
- Total interest paid: $181,720
Payment difference: $742 monthly Interest savings with 15-year: $264,600
Now evaluate what $742 monthly means to your specific budget. Does it come from discretionary spending you’d barely notice? Or does it mean sacrificing retirement contributions, emergency savings, or other important goals?
The Breakeven Analysis for Prepayment
Calculate when extra payments on a 30-year mortgage equal the forced payoff schedule of a 15-year mortgage. If you can afford a 15-year payment, you can always take a 30-year mortgage and prepay extra principal.
Using our $350,000 example, paying an extra $742 monthly on the 30-year mortgage pays it off in approximately 15 years while maintaining payment flexibility. You achieve similar results without committing to the higher payment.
The tradeoff involves interest rates. The 15-year mortgage has a 0.5 percentage point lower rate in our example. Over fifteen years, this rate advantage saves approximately $30,000 to $40,000 even when prepaying the 30-year mortgage to match the 15-year payoff schedule.
Flexibility has value. The 30-year mortgage with voluntary prepayment allows reducing or skipping extra payments during financial stress. The 15-year mortgage offers no flexibility—you must make the full payment regardless of circumstances.
Calculating Total Net Worth Impact
Project your net worth under both scenarios fifteen years forward.
15-Year Mortgage Scenario: Year 15 net worth includes:
- Home equity: $350,000 (fully paid off)
- Retirement accounts: Modest balance (less monthly contribution capacity)
- Emergency savings: Lower balance (less available cash flow)
30-Year Mortgage with Investment of Payment Difference: Year 15 net worth includes:
- Home equity: $180,000 (partially paid off)
- Retirement accounts: Substantial balance ($742 monthly invested over 15 years)
- Emergency savings: Healthy balance (better cash flow allowed more saving)
Run the numbers with realistic assumptions about investment returns, your actual ability to invest payment differences, and your household’s cash flow needs. Don’t assume investment discipline you haven’t demonstrated historically.
The Stress Test Analysis
Model both options under financial stress scenarios. What happens if one spouse loses income for six months? If major medical expenses hit? If a business opportunity requires capital?
The 30-year mortgage passes stress tests more easily. Lower required payments mean surviving income disruptions without touching savings or selling assets. The 15-year mortgage requires adequate reserves or facing potential payment default.
Conservative planners should weight stress scenarios heavily. Optimizing for best-case outcomes creates vulnerability during inevitable rough patches. Planning for worst-case scenarios ensures you survive challenges while still progressing financially.
Hybrid Strategies Combining Both Approaches
The 15-versus-30 choice isn’t strictly binary. Several strategies capture benefits from both options.
Start with 30, Prepay Like 15
Take a 30-year mortgage for maximum flexibility. Make additional principal payments equal to a 15-year payment schedule. This achieves 15-year payoff speed with 30-year payment flexibility.
Make extra payments monthly, quarterly, or annually—whatever frequency matches your cash flow. Some months you might skip extra payments due to other obligations. Other months you might pay even more than the 15-year schedule would require.
Automate extra payments when possible. Set up recurring additional principal payments through your lender’s online system. This creates forced savings while maintaining the ability to adjust or stop if circumstances change.
Track your progress against a 15-year amortization schedule. Seeing your accelerated equity growth and reduced interest payments motivates continued extra payments. Celebrate milestones like paying off five years early or saving $100,000 in interest.
The Refinance Strategy
Some homeowners start with 30-year mortgages then refinance to 15-year loans later. This provides low payments initially with aggressive payoff later.
Your early thirties might require 30-year payment flexibility while building careers and starting families. Your forties might bring substantially higher income making a 15-year refinance comfortable.
Refinancing costs typically run $3,000 to $6,000 in fees. Calculate breakeven periods on refinance costs versus interest savings. If you save $400 monthly in interest, a $5,000 refinance cost pays for itself in just over a year.
Interest rates at refinance time obviously matter greatly. Refinancing from a 6.5 percent 30-year mortgage to a 5.5 percent 15-year mortgage provides double benefits—lower rate and faster payoff. Refinancing from 6.5 percent to 6 percent provides less compelling benefits.
The 20-Year Mortgage Compromise
Twenty-year mortgages split the difference between 15 and 30-year terms. Payments sit between both extremes. Interest costs fall between both extremes. Payoff timing lands between both extremes.
Not all lenders offer 20-year mortgages as standard products. Those that do often price them closer to 15-year rates than 30-year rates. Shop around specifically for 20-year options if this term interests you.
A 20-year mortgage might be perfect for 40-somethings wanting mortgage-free retirement by 60 but finding 15-year payments too tight. It offers middle-ground compromise between affordability and aggressive payoff.
Using our $350,000 example at 6.25 percent interest, a 20-year mortgage requires approximately $2,500 monthly payment—splitting the difference between the $2,212 30-year payment and $2,954 15-year payment.
Biweekly Payment Plans
Biweekly payment programs split your monthly payment in half and charge it every two weeks. This results in 26 half-payments annually, equivalent to 13 full monthly payments instead of 12.
The extra payment annually goes entirely to principal. On a 30-year mortgage, biweekly payments typically cut payoff time to approximately 24 to 26 years while reducing total interest paid substantially.
Some lenders charge fees for biweekly payment programs. Avoid these fees by simply making one extra monthly payment annually on your own. The results match biweekly programs without fees.
Biweekly programs work well for people paid biweekly who want mortgage payments aligned with paychecks. They create forced acceleration without dramatically increasing payment amounts per paycheck.
Real-World Examples of Both Choices
These scenarios show how different families analyzed their situations and chose mortgage terms based on their specific circumstances.
The Johnson Family: 15-Year Success
The Johnsons, both 42 years old, earn $180,000 combined. They’re buying a $400,000 home with $80,000 down payment requiring a $320,000 mortgage. Both have stable government jobs with pension benefits.
They calculated a 15-year payment of $2,700 monthly versus a 30-year payment of $2,050 monthly. The $650 difference felt manageable given their $15,000 monthly take-home pay. They have $40,000 in emergency savings and max out retirement contributions already.
Choosing the 15-year mortgage means owning their home free and clear at age 57—eight years before planned retirement at 65. This allows substantial retirement saving acceleration in those eight payment-free years.
Their 15-year decision saved approximately $220,000 in interest. Having pensions covering basic retirement needs made aggressive mortgage payoff more attractive than building additional retirement investments.
The Martinez Family: 30-Year Wisdom
The Martinez family, ages 31 and 33, earn $95,000 combined. They’re buying their first home for $280,000 with a $250,000 mortgage after their down payment. One spouse works in commissioned sales while the other teaches.
A 15-year payment would be $2,110 monthly while a 30-year payment runs $1,580 monthly. The $530 difference represents significant portion of their $6,500 monthly take-home pay. They have only $8,000 in emergency savings and student loan debt of $35,000.
The 30-year mortgage preserved cash flow for building emergency savings, paying student loans, and handling the unexpected costs of first-time homeownership. They plan to prepay extra principal as income grows and debts decrease.
Their young age means typical career progression should significantly increase their income over the next decade. The flexibility to prepay later made more sense than committing to high payments on current income.
The Chen Family: Hybrid Approach
The Chen family, both 38, earn $140,000 combined. They bought a $370,000 home with $70,000 down requiring a $300,000 mortgage. Both work in tech with variable bonus income.
They chose a 30-year mortgage with $1,897 monthly payment instead of a 15-year mortgage requiring $2,531 monthly. However, they committed to paying $2,500 monthly when possible—matching the 15-year schedule.
Variable tech bonuses mean some years they prepay aggressively while other years they stick to base payments. This flexibility accommodates their income variability while building equity almost as fast as a true 15-year loan.
Their strategy saves significant interest compared to a straight 30-year mortgage while maintaining payment flexibility during lean bonus years. They’re on track to pay off their mortgage in approximately 17 years—faster than 30 but with more flexibility than 15.
Making Your Final Decision
After analyzing all factors, you need a framework for deciding which mortgage term suits your situation best. Use this decision tree to guide your choice.
Questions to Ask Yourself
Can you comfortably afford the 15-year payment while maintaining other financial obligations? If the answer is clearly yes with room to spare, the 15-year mortgage likely makes sense unless you have compelling reasons to maintain payment flexibility.
Do you have at least six months of expenses saved in emergency funds? If not, the lower payment of a 30-year mortgage helps you build emergency savings faster while maintaining adequate housing payments.
Are you maxing out retirement account contributions? If you’re not capturing full employer matches or maximizing tax-advantaged retirement savings, prioritize those before aggressive mortgage payoff. The tax benefits and employer matches exceed mortgage interest savings.
Do you have high-interest debt above 7 percent? Pay that off before choosing an aggressive mortgage. The interest differential makes eliminating high-interest debt first the mathematically superior choice.
How stable is your employment and income? Variable income or job uncertainty favor 30-year mortgages. Rock-solid employment with predictable income favor 15-year mortgages.
How old are you and when do you want to retire? Older buyers should strongly consider 15-year mortgages to ensure mortgage-free retirement. Young buyers have flexibility to start with 30-year loans.
Your Personal Risk Tolerance
Conservative personalities uncomfortable with debt should favor 15-year mortgages despite higher payments. The psychological benefit of faster payoff justifies the reduced flexibility for some people.
Aggressive personalities comfortable with calculated risk might prefer 30-year mortgages with disciplined investing of payment differences. This approach requires genuine investment discipline and higher risk tolerance.
Most people fall somewhere in between. A 30-year mortgage with regular but voluntary prepayment captures benefits from both approaches for moderate risk tolerance individuals.
Making the Commitment
Once you’ve chosen your mortgage term, commit to it fully. Don’t second-guess your decision quarterly based on market movements or friends’ choices.
If you chose a 15-year mortgage, budget other expenses around the higher payment. Don’t let payment stress tempt you to refinance to a 30-year loan later—you’d lose progress and pay additional closing costs.
If you chose a 30-year mortgage with prepayment intentions, set up automatic extra payments immediately. Don’t wait to “see how it goes.” Voluntary prepayment requires automation to succeed consistently.
Review your decision every three to five years as circumstances change. Major income changes, family changes, or financial goal shifts might justify refinancing to different terms.
