FHA Loan Limits for a Single-Family Home in a High-Cost Area

The Quick Read: The county where the house sits sets the maximum FHA base loan, and a high-cost county gets a higher cap than a typical one. Every county falls between a fixed floor and a fixed ceiling. The cap limits the loan, not the price you can pay or the amount you qualify for. Credit, income, debt ratios and the appraisal are separate tests that can leave you below the cap.

What an FHA Loan Limit Is (and Isn’t)

An FHA loan limit is the largest base mortgage the FHA will insure on a property in a given county. It is a ceiling on the insurance. It says nothing about whether you personally qualify for that amount.

That distinction trips up a lot of high-cost buyers. They see a big number for their county and assume it is their budget. It isn’t. Across the wholesale programs Lendmire places FHA files with, the cap is checked first, then everything else gets tested on its own terms. Credit score, income, debt ratios and cash reserves all sit outside the limit.

A few plain contrasts:

If you want the program basics before the limit mechanics, Lendmire’s FHA loan programs page covers who the loan is built for and how the file is reviewed.

How a County Gets Its Limit

Every county’s one-unit limit is built from the national conforming loan limit. The FHA floor is 65 percent of that conforming limit, and the FHA ceiling is 150 percent of it, per HUD’s Mortgagee Letter 2025-23. HUD updates both numbers once a year.

The conforming limit itself comes from the Federal Housing Finance Agency. FHFA’s announcement of the new conforming loan limits explains that the baseline moves with a national home price index. It also explains the local rule. Where 115 percent of a county’s median home value is higher than the baseline, that county gets a higher area limit. The statute caps the area limit at 150 percent of the baseline.

Put that into three buckets:

That’s the whole formula. Most counties land in the first bucket. High-cost counties land in the second or third. This is why a high-priced metro does not automatically get the maximum. The test is the median home value in the county, run through the 115 percent rule and then held to the cap.

What Makes an Area “High-Cost”?

An area is high-cost when its limit rises above the floor. The label is not a separate program. It is just a county whose median home value is high enough to lift the number.

Three things matter in practice.

County, not state. Two neighboring counties can carry different limits. A buyer who crosses a county line while house hunting can change the cap without changing the price.

Metro areas use the highest-median county. In metropolitan areas, HUD sets the limit using the county with the highest median price inside the metro, per the same Mortgagee Letter. That is why a modest county inside a pricey metro can show a limit above what its own prices would justify.

Special areas get a higher ceiling. Alaska, Hawaii, Guam and the U.S. Virgin Islands have their own higher ceiling. The Mortgagee Letter carries the details.

How the Loan Is Built, Step by Step

Here is how a purchase file moves from the limit to a real loan amount.

1. Look up the county limit. Use HUD’s mortgage limit lookup tool. Enter the county and the number of units. For a single-family home, that is one unit.

2. Fix the year by the case number. The limit in force is the one for the date the FHA case number is assigned. The closing date does not control it. HUD’s lender page says the current limits apply to case numbers assigned on or after the effective date. A purchase that straddles the year-end follows the case number date.

3. Test the base loan against the cap. The base loan is the mortgage amount before any financed upfront premium. HUD’s FHA purchase Q&A says the upfront premium is not counted when testing the area limit or the loan-to-value, and the total mortgage can be increased by the financed premium.

4. Run the loan-to-value test. On a purchase, the maximum financing is 96.5 percent of the adjusted value, with a 3.5 percent minimum investment from the buyer. Adjusted value is the lesser of the price (less any inducements) or the appraised value. That is the HUD formula, and it matches what Lendmire sees across the wholesale programs it places FHA loans with.

5. Take the lesser result. The insured base loan can’t exceed the county limit or the loan-to-value result. Whichever number is lower wins.

6. Underwrite the borrower. Only now does the file get tested for credit, income, ratios and reserves. Across the wholesale programs Lendmire works with, FHA purchase files start at a 580 decision score for the 3.5 percent minimum investment. The base debt ratios are 31 percent housing and 43 percent total with no compensating factors. Documented compensating factors can push those toward 40 and 50 at the top tier. The automated finding governs most files. All of this is subject to lender guidelines and full file review.

One more point on step 3. When someone enters a loan amount into the lookup tool, entering it with or without the financed premium matters. HUD’s lookup help page warns that the wrong entry may result in falsely exceeding limits. Always test the base loan.

A Worked Example in a High-Cost County

Say a buyer is under contract on a single-family home in a county that sits at or near the ceiling. Keep it in percentages.

The clean case. The home appraises at the contract price. The buyer puts 3.5 percent down. The base loan is 96.5 percent of the price. The 1.75 percent upfront premium is financed on top, so the note ends up a little over 98 percent of the price. The base loan sits under the county cap, so the cap never binds. The deal works on to credit, income and ratios.

The gap case. The price is high enough that 96.5 percent of it runs past the county cap. The base loan gets trimmed to the cap. The buyer covers the difference in cash, on top of the minimum investment. If that gap is small, a larger down payment may solve it. If it is large, the file likely belongs in a different loan type.

The appraisal case. The price clears the cap, but the appraisal comes in light. Now the loan-to-value test runs off the lower value. The loan shrinks, and the buyer covers the shortfall. In a high-cost market, a low appraisal is a common way for a file that looked fine on paper to land below its cap. Ask early for the appraisal plan and keep recent nearby sales ready in case a reconsideration request is needed.

The pattern holds in any high-cost county. The cap is one of three limits on the loan, and the lowest one sets the amount.

Mortgage Insurance on a Larger Loan

A larger base loan costs more in mortgage insurance, because both premiums scale with the loan. Here is how the structure works across the FHA files Lendmire places.

• Upfront premium: 1.75 percent of the base loan, financed into the mortgage.
• Annual premium: between 0.15 percent and 0.75 percent of the balance, depending on the term, the loan amount and the loan-to-value.
• How long it lasts: on a thirty-year loan above 90 percent loan-to-value, the annual premium stays for the full term. At or below 90 percent, it ends after eleven years.

These are program facts, not a price quote. The Loan Estimate shows the actual numbers for a file. A buyer near the ceiling should look at the annual premium line carefully, because it lands on the biggest balance the program will insure.

Where the General Rule Breaks

The county cap works the same way for most files. A few situations bend it.

Two- to four-unit homes. An owner-occupied home with two to four units has its own, higher limits. Look up the unit count that matches the property. Don’t reuse the one-unit number.

Alaska, Hawaii, Guam and the U.S. Virgin Islands. These areas have a higher ceiling, per the Mortgagee Letter noted above. Use the official figure.

Refinances. The same area limit caps the base loan on a refinance. The leverage rules differ by refinance type. Across the wholesale programs Lendmire works with:

Reverse mortgages. The FHA reverse mortgage for seniors is a different program with its own limit. It does not share the forward-mortgage county limits discussed here.

Limits don’t follow your closing date. A buyer who gets a case number late in the year keeps that year’s limit even if closing falls after the reset. The reverse also holds. Waiting for a new case number in January means the new limit applies.

What If the Price Is Above the Limit?

Start by sizing the gap. If the price is only a little above what the cap supports, a larger down payment usually fixes it. If it is well above, FHA may not fit the file.

The ceilings can line up. In the highest-cost counties, the FHA ceiling and the conforming ceiling are both set at 150 percent of the baseline, according to FHFA. The floors differ, though. The FHA floor is 65 percent of the conforming limit, so in an ordinary county a conventional loan can run much larger than an FHA loan.

Common Misreadings

“The top number is the FHA limit everywhere.” It is only the cap in the costliest counties. Most counties sit at the floor. Check the lookup tool.

“The limit includes the upfront premium.” It doesn’t. The premium is financed on top of the base loan.

“The limit is my price range.” The limit caps the loan. The price you can pay depends on the down payment, the appraisal and your qualifying ratios.

“FHA and conforming limits are unrelated.” FHA’s floor and ceiling are fixed percentages of the conforming baseline, which is why they move together from year to year.

“The limit changes when I close.” It follows the case number date.

“Approval follows from being under the cap.” It doesn’t. A base loan under the cap still has to pass credit, income, ratio and appraisal review. Nothing here is a commitment to lend.

Key Terms Defined

Base loan amount: The mortgage amount before any financed upfront premium, and the number tested against the county cap.

Floor: The lowest one-unit FHA limit, which is 65 percent of the conforming limit and applies in most counties.

Ceiling: The highest one-unit FHA limit outside special areas, which is 150 percent of the conforming limit.

Adjusted value: The lesser of the purchase price (less inducements) or the appraised value, used for the loan-to-value test.

Minimum required investment: The buyer’s own money in the deal, which is 3.5 percent on a purchase at the maximum financing.

Case number: The FHA identifier assigned to a file, whose date decides which year’s limit applies.
