FHA vs Conventional: The Real Cost Over Thirty Years

FHA is the loan that says yes when conventional says no. That is its entire purpose and it is a genuinely valuable thing. It is also, over thirty years, the more expensive loan by roughly twenty thousand dollars on a modest house — and the reason is a single word in a HUD rate table.

Both loans are worth having. The question is whether you're choosing FHA because you need it or because someone offered it first.

Who each one lets in

FHA's credit thresholds have been stable since HUD's Mortgagee Letter 10-29 set them. A decision credit score at or above 580 qualifies for maximum financing — 96.5% loan-to-value, the famous 3.5% down. Scores from 500 to 579 are capped at 90% loan-to-value, meaning 10% down. Below 500, there is no FHA loan.

Conventional lending has no single published floor; it's underwritten to investor guidelines that price risk continuously rather than in steps. Practically, conventional gets difficult in the low 600s and expensive well before that, and low-down-payment conventional programs carry their own overlays. The CFPB's summary of the difference is about as compact as it gets: conventional loans "typically cost less than FHA loans but can be harder to get."

So the honest ordering is: if you can qualify conventional at a reasonable price, take it. If you can't, FHA is not a consolation prize — it's the reason you get to buy a house this decade instead of the next one.

The insurance, which is the whole ballgame

Both loans charge you for insuring the lender against your default when you put down less than 20%. They just end differently.

On a conventional loan, private mortgage insurance is governed by the Homeowners Protection Act. Per the CFPB, you have the right to ask the servicer to cancel PMI when the balance is scheduled to fall to 80% of the home's original value, and the servicer "must automatically terminate PMI on the date when your principal balance is scheduled to reach 78 percent of the original value." It has an expiry date built into the loan.

FHA charges two premiums and one of them may never expire. There's an upfront premium of 175 basis points — 1.75% of the base loan amount, usually financed into the loan. Then an annual premium, collected monthly, whose duration is set by HUD's Mortgagee Letter 2023-05. On a 30-year FHA loan under the national conforming limit: original loan-to-value at or below 90% gets 50 basis points for 11 years; above 90% up to 95% gets 50 basis points for the mortgage term; above 95% gets 55 basis points for the mortgage term.

The standard FHA purchase is 96.5% loan-to-value. That is the bottom row. Mortgage term. For the life of the loan, uncancellable by paying down the balance or by the house appreciating.

Same house, both loans, thirty years

A $300,000 purchase, 30-year fixed, at the 6.65% average from Freddie Mac's survey for the week of August 20, 2026. Rates on the two programs differ in real life; holding them equal isolates the insurance, which is the actual variable.

FHA at 3.5% down

1. Base loan amount: $289,500. Upfront premium at 1.75%: $5,066.25, financed, so the loan closes at $294,566.25.
2. Principal and interest: about $1,891.01 a month.
3. Annual MIP at 55 basis points on the outstanding balance: about $135.01 in month one, drifting down slowly as the balance falls.
4. Starting monthly outlay before taxes and insurance: about $2,026.
5. Total mortgage insurance across 30 years: roughly $31,900 in annual premiums plus the $5,066 upfront — about $37,000.

Conventional at 5% down

1. Loan amount: $285,000. No upfront premium.
2. Principal and interest: about $1,829.60 a month.
3. PMI at 0.55% a year: about $130.62 a month.
4. Starting monthly outlay: about $1,960.
5. The scheduled balance crosses 80% of the $300,000 original value — $240,000 — during month 126. Write the cancellation letter and the PMI stops. Total PMI paid: roughly $16,500.

About $37,000 against about $16,500. Call it $20,000, and every dollar of it is insurance protecting somebody else. That gap is the honest cost of the easier approval, and it's worth paying when the alternative is not buying.

A wrinkle that cuts FHA's way: PMI rates are risk-priced. At a 640 credit score, conventional PMI can run well above the 0.55% used here, sometimes to the point that FHA's flat 55 basis points is cheaper month to month. Ask both lenders for the actual PMI quote at your actual score — not a table, a quote. That single number decides more of this than the interest rate does.

Loan limits move every year, in both programs

FHFA set the 2026 conforming baseline for one-unit properties at $832,750, with a high-cost ceiling of $1,249,125. FHA's limits are derived from that: for calendar year 2026, the nationwide forward mortgage floor is $541,287 and the ceiling is $1,249,125, effective for FHA case numbers assigned on or after January 1, 2026. The ceiling is 150% of the conforming baseline; the floor is the minimum applied in areas where 115% of the local median home price falls below it.

Both sets of numbers change annually. Look up your county's figure for the current year rather than trusting any dollar amount printed in an article, this one included.

The property has to pass, not just you

This is the part that surprises buyers in competitive markets. An FHA appraiser is doing two jobs: estimating value, and checking the house against FHA's Minimum Property Requirements. HUD's appraisal report guide requires the appraiser to list "deficiencies and/or lack of compliance with Minimum Property Standards (MPS) or Minimum Property Requirements (MPR)," and to state whether there are "physical deficiencies or adverse conditions that affect the livability, soundness, or structural integrity of the Property." If the answer is yes, the appraisal is conditioned on "repair or alteration of the condition" or on a required inspection by a qualified professional.

In practice that means peeling paint on a pre-1978 house, a roof at the end of its life, missing handrails, exposed wiring, or an inoperable furnace can stop the loan until somebody fixes them. On a fixer-upper, or a bank-owned property being sold strictly as-is, that can be fatal — the seller won't repair and the loan won't fund without repair. Conventional appraisals are far less prescriptive about condition.

Which is also why some listing agents in bidding wars steer sellers away from FHA offers. It isn't snobbery; it's a real risk of a repair demand two weeks before closing. If you're using FHA in a hot market, get a strong preapproval, keep your inspection contingency, and expect to compete on terms rather than on price.

Don't refinance out of FHA on autopilot

The standard advice is "take FHA now, refinance to conventional later once you have 20% equity." Sometimes that's exactly right — dropping a lifetime MIP is worth real money. But a refinance replaces your rate too, and if you got a low rate on the FHA loan, trading it for a higher one to escape $135 a month can lose you money for years. Run the break-even on the whole payment, not the insurance line alone; this site's refinancing article has the arithmetic. Refinancing into a worse rate to escape mortgage insurance is a mistake people make with real conviction.

How to actually decide

• Score at or above roughly 680 with 5% down available: get quotes on both, and let the actual PMI quote decide. Conventional usually wins.
• Score in the low 600s or below, or thin credit history: FHA is likely your loan, and the extra cost is the price of the door being open.
• Buying a house that needs work, or an as-is sale: conventional avoids the FHA property-condition gauntlet entirely.
• Eligible for a VA loan: price that first. VA requires no down payment and no monthly mortgage insurance at all, with a funding fee instead — 2.15% on a first-use purchase with less than 5% down, and waived entirely for veterans receiving compensation for a service-connected disability.
• First-time buyer either way: check your state housing finance agency before you lock anything. Down payment assistance often layers onto both programs, and this site's first-time homebuyer article covers how to find yours.
