What Is a Conforming Loan Limit?

A conforming loan is a mortgage that meets the size and underwriting rules of Fannie Mae and Freddie Mac, the government-sponsored companies that buy most home loans from lenders. The conforming loan limit is the maximum size of a loan those companies will purchase, and it is reset every year by the Federal Housing Finance Agency. A loan at or below the limit is conforming, and a loan above it is called a jumbo loan.

Because lenders can sell conforming loans to Fannie Mae and Freddie Mac, they generally offer them at lower rates and with more flexible terms. Jumbo loans carry more risk for the lender and usually come with higher rates and stricter requirements. The limit therefore defines a practical line in mortgage pricing.

For 2026, the conforming loan limit for a single-family home in most of Pennsylvania is $832,750, up from $806,500 the year before. This is the baseline limit for standard cost areas, which includes the Philadelphia metro and the counties I serve. In designated high-cost areas the ceiling is higher, but none of the six counties I serve fall into that category, so the baseline applies.

The limit applies to the loan amount, not the purchase price. A buyer putting 10% down on an $850,000 home needs a $765,000 loan, which is conforming, even though the price exceeds the limit. The question is always about the size of the mortgage, not the price of the home.

The conforming loan limit tracks home prices. Each year the FHFA compares current home prices to previous years, and when prices rise, the limit rises with them. That is why the limit has climbed steadily over the past several years as values increased across the region.

For buyers, the annual adjustment matters because a loan that was jumbo last year can become conforming this year, and a single rate improvement can be worth thousands of dollars in interest over the life of a loan. If you are shopping near the limit, ask your lender which year's limit applies to your rate lock and your closing date.

Loans above the conforming limit are jumbo loans. Jumbo loans are not sold to Fannie Mae or Freddie Mac, so lenders price them to their own risk, and they typically carry slightly higher rates, larger down payment requirements, and stricter credit and reserve standards.

In the Philadelphia suburbs, where prices in some towns exceed the limit territory, buyers often face a choice: keep the loan at or below the conforming limit with a larger down payment, or take a jumbo loan. Running both scenarios with a lender shows the real monthly difference, which is sometimes smaller than buyers expect because jumbo rates can be competitive.

For the six counties I serve, the baseline conforming limit is the one that matters. Philadelphia, Montgomery, Bucks, Chester, Delaware, and Berks Counties are all standard cost areas for 2026 purposes. No county in the region qualifies for the higher high-cost ceiling, which applies to places like parts of California and New York.

That means a buyer in Blue Bell and a buyer in Fishtown face the same conforming limit, even though their price ranges differ. If you are financing a higher-priced purchase in any of these counties, confirm the current limit with your lender before you build your budget around a loan that turns out to be jumbo.

The conforming limit determines which mortgage shelf your loan sits on, and that affects your rate. I tell buyers shopping near the limit to have their lender price both a conforming and a jumbo scenario, because the down payment that keeps you conforming can save you more than it costs.

The limits change every year, so never rely on a number from an older article or a friend's closing. Ask your lender for the limit that applies to your loan, and know whether your target home puts you above the line.
