How FHA Loan Limits Work

Of all the rhythms in the American real estate market, few are as consistent as the late-year announcement of new home loan limits. Every year, typically in November or early December, the Federal Housing Administration (FHA) releases a schedule detailing the maximum mortgage amount it will insure for single-family homes in every county across the United States.

A higher limit can mean the difference between affording a home in their desired community or being priced out, depending on circumstances. But this yearly ritual often prompts a fundamental question: why do these limits change? The process is not an arbitrary adjustment or a whimsical decision made behind closed doors.

Annual FHA loan limit adjustments are a direct reflection of the nation's economic health, specifically the fluctuations in home values across the country. They are the result of a precise mathematical formula, one that links the government-insured FHA loan program to the much larger conventional mortgage market.

A Legislative Mandate

The foundation for the annual FHA loan limit adjustment is in the National Housing Act of 1934. This law was established during the Great Depression to help American families.

From the outset of the FHA program, it was evident that this government-backed home loan program should support workforce housing and promote homeownership among average American families, rather than subsidizing the purchase of luxury properties or investment properties. Therefore, the concept of a maximum mortgage amount that the FHA would insure was integral to the program's design.

How Conforming Loan Limits Affect FHA Loan Limits

To understand why FHA limits change, one must first understand the concept of a "conforming loan." The majority of conventional home loans in the United States are conforming loans, meaning they meet the underwriting criteria and funding guidelines set by Fannie Mae and Freddie Mac.

The maximum dollar amount for a mortgage that Fannie Mae or Freddie Mac will purchase is known as the conforming loan limit (CLL).

This limit is set annually by the Federal Housing Finance Agency (FHFA). HERA legally requires the FHFA to adjust the CLL each year to reflect the changes in typical U.S. home prices.

To do this, the FHFA analyzes data from its House Price Index (HPI), a broad measure of single-family home price movements. When average home prices have increased, the FHFA raises the conforming loan limit by the same percentage.

One Size Fits All?

The calculation is not a single, one-size-fits-all number. There is a three-tiered system for FHA loan limits: a national "floor," a national "ceiling," and a method for setting limits in between. This tiered system ensures a baseline level of access everywhere while also providing higher limits in a handful of designated high-cost markets.

The FHA loan limit floor is the lowest possible limit for any county in the country. It is calculated as 65 percent of the national conforming loan limit. Having the floor guarantees that even in areas with the most affordable housing, the FHA loan remains a viable financing tool. It ensures that homebuyers in rural counties or areas with lower median home values are not left behind.
For example, if the national conforming loan limit is set at $800,000, the FHA floor would be $520,000. No matter how low a county's median home price is, its FHA limit can be no lower than this floor amount.

At the other end of the spectrum is the FHA loan limit ceiling. This is calculated as 150 percent of the national conforming loan limit and applies only to a specific list of designated high-cost counties. These are typically major metropolitan areas where home values are significantly higher than the national average, such as the areas surrounding New York City, Los Angeles, San Francisco, plus Washington, D.C.

High-Cost Areas

The law also carves out special, even higher ceilings for expensive markets such as Alaska, Hawaii, Guam, and the U.S. Virgin Islands, recognizing their unique construction costs and market conditions.

For all other counties—the vast majority that fall somewhere between the lowest and highest cost areas—local housing values determine the FHA loan limit. HUD calculates the median sale price for homes in each specific Metropolitan Statistical Area (MSA).

The FHA loan limit for a county within that MSA is then set at 115 percent of its median home sale price. However, this calculated local limit is still bound by the national floor and ceiling.

If 115 percent of the local median price is lower than the national floor, the county's limit will be raised to the floor. Conversely, if 115 percent of the local median price is higher than the national ceiling, the limit will be capped at the ceiling.
