Conforming vs. Non-Conforming Loan: Limits, Costs, and Jumbo Options

A conforming loan falls within the dollar limits and underwriting rules that let Fannie Mae or Freddie Mac buy it from your lender; a non-conforming loan does not, either because the amount is too large (a jumbo loan) or because it runs through a separate government program like FHA, VA, or USDA. The practical difference in conforming vs. non-conforming loans shows up in your interest rate, down payment, credit score requirements, and whether you pay mortgage insurance. For 2026, the baseline conforming limit on a single-family home is $832,750 in most of the country, rising to $1,249,125 in high-cost counties.¹

The Dollar Line That Separates Them

The Federal Housing Finance Agency recalculates the conforming loan limit each year based on changes in average home prices.² For 2026, the baseline for a one-unit property is $832,750 across the contiguous United States, the District of Columbia, and Puerto Rico.¹

Not every county uses that figure. Where 115% of the local median home value exceeds the baseline, the limit rises, capped at 150% of the baseline. For 2026 that ceiling is $1,249,125 for a one-unit property, and parts of California, the New York metro area, and other expensive markets regularly hit it. Alaska, Hawaii, Guam, and the U.S. Virgin Islands have their own elevated numbers: a $1,249,125 baseline and a $1,873,675 ceiling for a one-unit home.¹

Limits also rise for multi-unit properties you occupy as a primary residence. The 2026 baseline figures for the contiguous states:³

Two units: $1,066,250, with a high-cost ceiling of $1,599,375.
Three units: $1,288,800, with a high-cost ceiling of $1,933,200.
Four units: $1,601,750, with a high-cost ceiling of $2,402,625.

Loans priced between the baseline and the high-cost ceiling in qualifying counties are sometimes called high-balance conforming loans. Fannie Mae or Freddie Mac still buy them, but lenders typically price them slightly higher because the enterprises charge elevated guarantee fees on larger balances. You can look up your specific county’s limit on the FHFA’s website.

Why Conforming Loans Usually Cost Less

When your lender can sell your loan to Fannie Mae or Freddie Mac, capital flows back into the lending pool and the lender does not have to carry the risk on its own books. That secondary-market access is the reason conforming loans tend to carry lower rates and more flexible terms than non-conforming ones. Everything downstream, from your rate quote to how much the lender insists you put down, traces back to whether the loan can be sold.

What a Conforming Loan Requires of You

Staying under the dollar limit is necessary but not sufficient. Fannie Mae and Freddie Mac also set underwriting standards your loan has to meet before they will buy it.

Credit Score and Debt-to-Income

Fannie Mae requires a minimum FICO score of 620 for fixed-rate conforming loans and 640 for adjustable-rate mortgages.⁴ Higher scores earn better pricing. A borrower at 740 will see noticeably lower rates than one at 660 even though both technically qualify. Most conforming loans allow a back-end debt-to-income ratio up to about 45%, and automated underwriting sometimes approves ratios as high as 50% for borrowers with strong compensating factors like substantial savings.

Down Payment and PMI

Conforming loans allow down payments as low as 3% for qualifying buyers, one of their main advantages over jumbo loans. The trade-off is mortgage insurance. Put down less than 20% and you will pay private mortgage insurance, which protects the lender if you default.⁵ PMI typically runs between 0.3% and 1.5% of the original loan amount per year, depending on your credit score and loan-to-value ratio. Once your equity reaches 20% you can request removal, and your servicer must automatically cancel PMI once equity hits 22%.

When Your Loan Goes Jumbo

A mortgage that exceeds the conforming limit for its county is a jumbo loan.² Because Fannie Mae and Freddie Mac cannot buy it, the lender either holds the loan or sells it to a private investor. The qualification standards tighten accordingly.

Most lenders want a credit score of at least 700, and many prefer 720 or higher. Down payments typically start at 10% and can run as high as 25% or 30% depending on the lender and loan size. Borrowers also need to show significant cash reserves after closing, often six to twelve months of mortgage payments in liquid accounts. Debt-to-income ratios usually need to stay at or below 43%, stricter than conforming guidelines allow.

Rates on jumbo loans have historically run higher than conforming rates because lenders take on more risk without a government-sponsored backstop. The spread moves with market conditions but has typically been a quarter to three-quarters of a percentage point. On a $1 million loan, even a quarter-point difference adds up to thousands over the life of the mortgage. One potential upside: many jumbo loans do not require PMI even with less than 20% down, because the larger down payment already provides substantial lender protection. The PMI savings can partially offset the higher rate, though they rarely cancel it out entirely.

The Government-Backed Alternatives

Not every non-conforming loan is a jumbo. Three federal programs insure or guarantee mortgages that fall outside Fannie Mae and Freddie Mac’s rules, each aimed at a specific group of borrowers.⁶ These loans are non-conforming in the technical sense but carry their own government backing, which keeps rates competitive.

FHA Loans

The Federal Housing Administration insures loans for borrowers who might not qualify for conventional financing. The minimum down payment is 3.5% with a credit score of 580 or higher. Borrowers with scores between 500 and 579 can still qualify but have to put at least 10% down. FHA loans are more flexible on debt-to-income as well, with a 43% baseline that can stretch to 50% or higher through automated underwriting. The catch is FHA mortgage insurance, which includes both an upfront premium and an annual premium that lasts for the life of the loan if you put down less than 10%.

VA Loans

The Department of Veterans Affairs guarantees loans for eligible veterans, active-duty service members, and surviving spouses. The signature benefit is zero down payment, as long as the purchase price does not exceed the appraised value.⁷ VA loans require no private mortgage insurance. Borrowers pay a one-time funding fee instead, which can be rolled into the loan. The VA sets no hard minimum credit score, but individual lenders typically look for at least 620. There is no strict debt-to-income cap either; the VA focuses on whether the borrower has enough residual income to cover basic living expenses after all monthly obligations.

USDA Loans

The Department of Agriculture’s guaranteed loan program serves low- and moderate-income borrowers buying in eligible rural areas. Like VA loans, USDA loans offer 100% financing with no down payment.⁸ Household income cannot exceed 115% of the area median income, and the property must be in a location the USDA classifies as rural. Debt-to-income limits are tighter than FHA, generally 29% on the front end and 41% on the back end, though the USDA’s automated system can approve slightly higher ratios.

Figuring Out Which One Fits You

Start with two numbers: how much you need to borrow and where the property is located. Pull up the FHFA’s county-level lookup and compare your loan amount against the 2026 limit for that specific county.² If you are buying a multi-unit property, use the limit for the right number of units, since those thresholds run substantially higher.³

If your loan sits below the limit, a conforming loan is usually the best starting point. You will generally get the lowest rate and most flexible terms, assuming your credit, income, and down payment meet enterprise guidelines. Above the limit, you are in jumbo territory, which means preparing for a higher down payment, stronger credit expectations, and a slightly higher rate.

If your credit score or savings make conforming qualification difficult, check whether you are eligible for FHA, VA, or USDA financing. A veteran who could technically get a conforming loan might still come out ahead with the VA’s zero-down option. A buyer in a rural area with moderate income could save money through USDA even if the loan amount is well within conforming limits. The best loan type is not always the one that matches your loan amount to a limit chart. It is the one where the full package of rate, down payment, insurance, and qualification flexibility works for your situation.
