You can get a 5 year mortgage, but the term covers three very different products, and only some lenders offer each one. It can mean a fully amortizing fixed-rate loan paid off in sixty monthly installments, an adjustable-rate mortgage with a five-year fixed period before the rate starts moving, or a balloon loan where a large lump sum comes due at the end of year five. Which one fits depends on your income, how long you plan to keep the property, and how much risk you can absorb.
The Three Products Sold as a Five-Year Mortgage
Fully Amortizing Five-Year Fixed
This is the literal version: sixty monthly payments and the loan is gone. On a $400,000 balance, the payment runs roughly three times what you would owe on a thirty-year term. Few traditional banks offer the product because it does not fit the secondary market where loans get bundled and sold to Fannie Mae or Freddie Mac. Credit unions and private wealth management banks are the most likely sources, and they hold these loans in their own portfolios rather than reselling them. You pay dramatically less interest over the life of the loan and own the home outright in five years. The price is a payment most households cannot carry.
Five-Year Adjustable-Rate Mortgage
The far more common version of a “five-year mortgage” is an adjustable-rate mortgage where the rate is fixed for the first five years and then begins adjusting. The most widely available version today is the 5/6 ARM, which resets every six months after the initial fixed period ends.1Freddie Mac. Considering an Adjustable-Rate Mortgage? Here’s What You Should Know The older 5/1 ARM, which adjusts once a year, still exists but is less prevalent. Both tie their adjustments to a benchmark index, typically the Secured Overnight Financing Rate. These products appeal to borrowers who plan to sell or refinance inside the five-year window and want a lower starting rate than a thirty-year fixed loan.
Five-Year Balloon Mortgage
A balloon mortgage sets monthly payments as if the loan had a longer term, but the remaining balance comes due as one large payment at the end of five years. Federal regulations define that final balloon payment as one more than twice the size of the earlier scheduled payments.2Legal Information Institute. Definition: Balloon Payment from 15 USC 1639c(b)(2) If you cannot sell, refinance, or produce the lump sum when the balloon is due, you face default. Balloon loans generally cannot qualify as “qualified mortgages” under federal consumer protection rules, with narrow exceptions for lenders operating in rural or underserved areas.3Office of the Law Revision Counsel. 15 USC 1639c – Minimum Standards for Residential Mortgage Loans
What It Takes to Qualify
Federal law requires any residential mortgage lender to verify that you can reasonably afford the payments based on documented income, current debts, and employment.3Office of the Law Revision Counsel. 15 USC 1639c – Minimum Standards for Residential Mortgage Loans For a fully amortizing five-year loan, that scrutiny is sharper than on a thirty-year product because the payments are so much larger.
Debt-to-Income Ratio
Your debt-to-income ratio measures how much of your gross monthly income goes toward debt payments. For a qualified mortgage the ceiling is generally 43%.4Navy Federal Credit Union. Debt-to-Income Ratio (DTI): Why It’s Important and How to Calculate It Because the payments on a five-year loan are so large, fewer borrowers can stay under that line. Some portfolio lenders, typically credit unions or private banks serving high-net-worth clients, may stretch the limit to 50% if you can show strong compensating factors like significant liquid reserves.
Credit Score and Cash Reserves
Most lenders offering short-term mortgage products look for a credit score of 720 or higher. Because these are portfolio loans, each institution sets its own standards, and those standards tend to be stricter than what you would see on a government-backed product. Expect to document substantial cash reserves, often twenty-four months of mortgage payments sitting in accounts the lender can verify.
Down Payment and Loan Size
A down payment of at least 20% is a common requirement, which also lets you avoid private mortgage insurance. For 2026, the conforming loan limit for a one-unit property in most of the country is $832,750, rising to $1,249,125 in designated high-cost areas.5U.S. Federal Housing Finance Agency. FHFA Announces Conforming Loan Limit Values for 2026 Since fully amortizing five-year fixed loans sit in portfolio rather than selling to the GSEs, that conforming limit matters less for them. It does matter for 5/6 ARMs, which Fannie Mae and Freddie Mac purchase, and where exceeding the limit pushes you into jumbo loan territory with tighter underwriting.
What Happens to an ARM After Year Five
If you lean toward a 5/6 ARM, this is where the risk lives. Federal rules require ARMs to carry three layers of rate caps that limit how far the rate can move.6Consumer Financial Protection Bureau. What Are Rate Caps with an Adjustable-Rate Mortgage (ARM), and How Do They Work?
- An initial adjustment cap limits the first rate change after the fixed period ends, commonly two or five percentage points above or below your starting rate.
- A subsequent adjustment cap limits each later adjustment, most often to one or two percentage points per period.
- A lifetime cap limits the total increase over the life of the loan, most commonly five percentage points above the initial rate.
Even with those caps, the payment shock can be real. A starting rate of 6% with a lifetime cap of five points could eventually reach 11%. On a $400,000 balance, that swing would add hundreds of dollars to the monthly payment. If you plan to keep the home long past year five, think hard about whether you can absorb those increases, or whether a fixed-rate product is the safer choice.
Check the Prepayment Penalty Before You Sign
On a qualified mortgage, prepayment penalties are prohibited unless the loan is a fixed-rate product that is not classified as higher-priced, and even then the penalty amount and duration are limited. Adjustable-rate qualified mortgages cannot carry prepayment penalties at all. High-cost mortgages cannot include any prepayment penalty.7Office of the Law Revision Counsel. 15 USC 1639 – Requirements for Certain Mortgages
A fully amortizing five-year loan held in portfolio sits outside many of those guardrails, and the lender’s own note controls. Ask directly whether the loan includes a prepayment penalty, and get the answer in writing before closing. If your plans change and you need to refinance or sell early, that one clause can cost you thousands.
