The mortgage you choose affects your monthly payment, your total interest cost, your risk exposure, and your flexibility for decades. At 6% rates in 2026, the choice between a 30-year fixed, 15-year fixed, and adjustable-rate mortgage involves real tradeoffs worth understanding before you sign. Here is what you need to know about each type.
30-Year Fixed Rate Mortgage
The most common mortgage in the United States. Your interest rate and monthly payment remain constant for the entire 30-year loan term. Predictability is the primary benefit.
Current rate (2026): approximately 6.0-6.5% for well-qualified borrowers.
Monthly payment on $320,000 loan at 6.25%: $1,970
Total interest paid over 30 years: $389,200
Best for: Buyers who plan to stay in the home long-term, who value payment stability, and who want to free up monthly cash flow for other goals (investing, paying off other debt).
Drawback: Early payments are almost entirely interest. In year one of a $320,000 loan at 6.25%, you pay approximately $19,800 in interest and only $3,840 in principal. Equity builds slowly at first.
15-Year Fixed Rate Mortgage
Same stability as the 30-year but paid off in half the time. Typically carries a rate 0.5-0.75% lower than the 30-year equivalent.
Current rate (2026): approximately 5.25-5.75% for well-qualified borrowers.
Monthly payment on $320,000 loan at 5.5%: $2,616
Total interest paid over 15 years: $151,000
Savings vs 30-year: $238,000 in interest, plus the home is paid off 15 years earlier.
Best for: Buyers who can comfortably afford the higher monthly payment, who want to build equity faster, and who prioritize being mortgage-free before retirement.
Drawback: The higher payment reduces monthly cash flow flexibility. A job loss or income reduction is harder to manage with a higher required payment.
Adjustable Rate Mortgages (ARMs)
ARMs have a fixed rate for an initial period, then adjust annually based on a benchmark index. A 5/1 ARM is fixed for 5 years, then adjusts each year. A 7/1 ARM is fixed for 7 years, then adjusts.
Current rate (2026): 5/1 ARM approximately 5.0-5.5%, 7/1 ARM approximately 5.25-5.75%.
Best for: Buyers who are confident they will sell or refinance before the fixed period ends, and who want the lower initial rate. Particularly relevant in 2026 if you believe rates will fall significantly in 3-7 years and you plan to refinance.
Risk: If you stay past the fixed period and rates are higher when your loan adjusts, your payment increases. ARMs have caps on how much the rate can increase per year and over the life of the loan (typically 2% per year, 6% lifetime), but a 6% increase on a large loan balance is significant.
FHA Loans
Government-backed loans insured by the Federal Housing Administration. Allow lower credit scores (580+ for 3.5% down) and lower down payments than conventional loans. Require mortgage insurance premiums: 1.75% upfront plus 0.55% annually (cannot be removed on loans with original LTV above 90%).
Best for: First-time buyers with limited savings or credit scores in the 580-680 range who cannot qualify for conventional financing. See our full guide: How to Buy a House in 2026.
VA Loans (Veterans Only)
Zero down payment, no PMI, competitive rates. Available to eligible veterans, active-duty service members, and surviving spouses. A funding fee (1.4-3.6%, waived for disabled veterans) replaces mortgage insurance. If you are eligible, this is almost always the best mortgage product available to you.
The 30-Year vs 15-Year Decision Framework
If you can afford the 15-year payment comfortably (not straining your budget), the 15-year wins mathematically on total interest cost and time to payoff. If the 15-year payment would leave no room for retirement savings, emergency fund maintenance, or other financial goals, the 30-year with intentional extra principal payments toward the loan can be a middle path. Extra payments on a 30-year can reduce the effective payoff timeline without the risk of a payment you cannot make in a tough month.
