How FHA Loan Limits Are Calculated
FHA loan limits are not a single national number — they are calculated on a county-by-county basis and adjusted every year based on changes in local home prices. The system is anchored to the Federal Housing Finance Agency's (FHFA) conforming loan limit, which is the maximum amount Fannie Mae and Freddie Mac will purchase. FHA then applies its own formula to determine local limits.
The calculation uses two boundaries. The floor is set at 65% of the national conforming loan limit — this is the minimum FHA limit that applies in every county nationwide, even those with the lowest home prices. The ceiling is set at 150% of the conforming limit and caps the maximum FHA loan in the most expensive markets. Counties with median home prices between those two endpoints receive a limit based on 115% of their local median.
In practice, the majority of counties across the country sit at the floor because median home prices in those areas fall below the threshold that would trigger a higher calculation. High-cost counties — typically those with significantly elevated real estate markets — receive higher limits, up to the national ceiling. This structure is designed to make FHA accessible in affordable markets while still providing meaningful coverage where housing is more expensive. Meeting other FHA qualification requirements is equally important once you confirm the loan amount falls within your local limit.
2025 FHA Loan Limits by Property Type
For 2025, the national conforming loan limit is $806,500 for a single-family home. Applying FHA's formula, the floor for a one-unit property is $498,257 and the ceiling is $1,209,750. Multi-unit properties receive proportionally higher limits because they carry higher purchase prices.

How to Find Your County's FHA Limit
HUD publishes a free lookup tool that displays the exact FHA loan limit for every county and metropolitan statistical area (MSA) in the country. You can access it directly through HUD's website by searching for your county name or FIPS code. The tool displays limits for all four property types (1-unit through 4-unit) and shows whether your county is classified as low-cost, high-cost, or somewhere in between.
As a general rule, if you are purchasing in a county where home prices are near or below the national median, your limit is almost certainly the floor — $498,257 for a single-family home. Higher limits only apply in counties where the median home price significantly exceeds the national average. Your lender confirms the applicable limit during the pre-approval process, so you will know your maximum FHA loan amount before you begin shopping for homes.
The limit applies to your loan amount, not the purchase price
A common point of confusion: FHA loan limits cap the loan amount, not the home's purchase price. If your county's limit is $498,257 and you want to buy a $515,000 home, you can still use FHA — you would just need a larger down payment to bring the loan amount below the cap. In this example, a down payment of roughly $16,743 (about 3.3%) plus the standard 3.5% minimum would get you under the limit.

What to Do When You Need More Than the FHA Limit
If the home you want to purchase requires a loan amount above your county's FHA ceiling, you have two primary alternatives: a conventional conforming loan or a jumbo loan. Each has different qualification standards and trade-offs compared to FHA.
Conventional Conforming Loan
Jumbo Loan
When you are just barely over the limit
If your target loan amount exceeds the FHA limit by a small margin — say $5,000 to $15,000 — it often makes more sense to increase your down payment slightly to bring the loan under the FHA cap rather than switching to a conventional or jumbo product. The qualification flexibility and lower credit requirements of FHA may save you more than the additional upfront cash costs. Your lender can run the math on both scenarios quickly.
FHA Limits for 2–4 Unit Properties
One of FHA's most underutilized features is its support for owner-occupied multi-unit properties — duplexes, triplexes, and fourplexes. FHA allows you to purchase a 2–4 unit property with the same 3.5% down payment as a single-family home, provided you live in one of the units as your primary residence. The loan limits for these properties are substantially higher than single-family limits to account for their greater purchase prices.
This creates a powerful opportunity for first-time buyers and investors alike. By living in one unit and renting the others, you can offset a significant portion of your mortgage payment with rental income. FHA even allows you to use projected rental income from the non-owner-occupied units to help you qualify for the loan — up to 75% of the appraised fair market rent.
The trade-off is that FHA requires three months of PITI reserves (principal, interest, taxes, and insurance) in your bank account after closing for 3–4 unit purchases. This is a higher bar than single-family purchases, which typically have no reserve requirement. You will also need an FHA appraisal that accounts for the income-producing nature of the property.
The house-hacking advantage
Purchasing a duplex or triplex with FHA financing at 3.5% down is one of the most accessible entry points into real estate investing. The rental income from the additional units can substantially reduce — or in some cases fully cover — your monthly housing cost. Combined with FHA's flexible credit score requirements, this strategy makes multi-unit ownership achievable for borrowers who might otherwise be priced out of the investment property market.
How FHA Limits Have Changed
FHA loan limits have increased steadily over the past several years, tracking the upward movement in home prices nationwide. The trend reflects the broader housing market — as home values rise, the conforming loan limit increases, and FHA limits follow.
The 2025 floor remained unchanged from 2024 while the ceiling increased, reflecting continued price growth concentrated in high-cost markets. For most borrowers, the floor is the number that matters — and at nearly $500,000, FHA covers the vast majority of home purchases nationwide.
