When you sit down with a lender for the first time, the question almost always surfaces within the first ten minutes: FHA or conventional? It sounds like a technicality, but the answer can shift your monthly payment by hundreds of dollars, determine whether you even qualify, and shape how much equity you build over the next decade. I’ve walked through this decision with enough borrowers — friends, family, and readers who emailed after their offers fell apart — to know that the wrong choice isn’t always obvious until the closing costs hit.
This guide breaks down the FHA loan versus conventional mortgage comparison across every dimension that matters: credit requirements, down payments, mortgage insurance, loan limits, and the scenarios where each product genuinely wins. By the end, you’ll have a clear framework for your own situation — not a generic recommendation that fits nobody.
What Each Loan Type Actually Is
An FHA loan is a mortgage insured by the Federal Housing Administration, a government agency under the Department of Housing and Urban Development (HUD). The lender is still a private bank or credit union, but the federal guarantee protects them if you default. That backstop is why lenders can extend credit to borrowers with lower scores and thinner down payments.
A conventional mortgage, by contrast, carries no government insurance. It conforms to standards set by Fannie Mae and Freddie Mac — the two government-sponsored enterprises that buy loans from lenders and package them into securities. Because lenders bear more of the risk, they apply stricter qualification standards. Loans within Fannie and Freddie’s purchase limits are called conforming loans; anything above is a jumbo, which sits in its own category entirely.
The practical implication: FHA loans exist specifically to expand access to homeownership. Conventional loans exist to serve borrowers who already look reliable on paper. Neither is inherently superior — the right one depends on where you sit on that risk spectrum right now.
Credit Score Requirements: Where the Gap Is Real
FHA loans accept credit scores as low as 500. Borrowers with scores between 500 and 579 must put 10% down; those with 580 or above qualify for the 3.5% minimum down payment. Those thresholds are the official HUD floor, though individual lenders often set overlays — internal minimums that run 20 to 40 points higher than HUD requires.
Conventional loans typically require a minimum score of 620 to qualify for any product. To access the most competitive rates and avoid pricing penalties — known as loan-level price adjustments (LLPAs) — you generally want a score of 740 or above. A borrower at 680 can get a conventional loan but will pay a noticeably higher rate than someone at 760.
Here’s where it gets counterintuitive: once your score crosses roughly 720 and you have a stable income, conventional pricing often beats FHA even though FHA’s floor is lower. The MIP (mortgage insurance premium) on an FHA loan persists regardless of your score, while a conventional borrower with strong credit pays lower PMI rates and can eventually eliminate the cost entirely. If your score is between 620 and 679, run both scenarios through a mortgage calculator before assuming FHA is the cheaper path.
Down Payment Differences and What They Cost You
FHA’s minimum down payment of 3.5% is a real draw for first-time buyers in high-cost markets. On a $400,000 home, that’s $14,000 — a meaningful but achievable target for households that have been renting and saving simultaneously. Down payment assistance programs at the state level often layer on top of FHA loans as well, reducing the cash required at closing even further.
Conventional loans offer down payment options starting at 3% through programs like Fannie Mae’s HomeReady and Freddie Mac’s Home Possible, which target low-to-moderate income borrowers. A standard conventional loan without income restrictions typically starts at 5% down. At 20%, the borrower eliminates private mortgage insurance completely — a threshold that dramatically changes the long-term cost picture.
A smaller down payment means a larger loan balance and more interest paid over 30 years. On a $350,000 purchase, the difference between 3.5% down ($12,250) and 10% down ($35,000) adds roughly $22,750 to your loan principal. At a 7% rate over 30 years, that difference compounds to more than $54,000 in additional interest. The down payment isn’t just an upfront cost — it restructures your entire amortization schedule.
If your savings can comfortably cover 20% down without depleting your emergency fund, conventional is almost always the cleaner financial move. If getting to that threshold would take another four years of renting, the math may favor buying sooner with a lower down payment and building equity now.
Mortgage Insurance: The Cost Nobody Reads Carefully
This is the section most borrowers skim — and it’s where the most significant long-term cost difference hides.
FHA loans carry two layers of mortgage insurance. The upfront mortgage insurance premium (UFMIP) equals 1.75% of the loan amount, paid at closing or rolled into the loan. On a $300,000 loan, that’s $5,250 added to your balance on day one. The annual MIP, paid monthly, ranges from 0.15% to 0.75% depending on loan term, loan-to-value ratio, and loan size. For most 30-year loans with less than 10% down, it sits at 0.55% annually.
The critical detail: FHA MIP on loans originated after June 2013 with less than 10% down persists for the life of the loan. You cannot cancel it by reaching 20% equity the way you can with conventional PMI. The only exits are refinancing into a conventional loan or selling the property.
Conventional PMI, by contrast, is cancellable. Once your loan-to-value ratio reaches 80% — either through payments, appreciation, or a combination — you can request cancellation. Federal law (the Homeowners Protection Act) requires automatic cancellation when the LTV hits 78% based on the original amortization schedule. PMI rates on conventional loans vary by score and LTV but typically run between 0.2% and 1.5% annually. A borrower with a 720 score and 10% down might pay around 0.5% annually — comparable to FHA — but with an expiration date.
Loan Limits and Property Eligibility
FHA loan limits are set by county and updated annually. For 2025, the baseline conforming limit for FHA in low-cost areas is $524,225 for a single-family home, while high-cost markets like San Francisco and New York metro reach $1,209,750. These limits cap how much you can borrow with FHA financing, regardless of your income or creditworthiness.
Conventional conforming loan limits for 2025 sit at $806,500 in most of the country, with high-cost area ceilings matching FHA’s top tier. Above these limits, you enter jumbo territory, which carries different underwriting standards and is outside this comparison.
Property eligibility differs meaningfully. FHA has stricter appraisal standards — the property must meet HUD’s minimum property requirements (MPRs), which cover structural soundness, safety, and habitability. Homes with peeling paint on pre-1978 structures, broken windows, missing handrails, or active roof leaks can fail FHA appraisal and require repairs before closing. Sellers who’ve dealt with this call it a deal-killer on fixer-uppers.
Conventional appraisals evaluate market value but don’t impose the same condition checklist. A home with cosmetic issues — dated fixtures, worn carpet, minor deferred maintenance — will pass a conventional appraisal far more easily than an FHA one. If you’re buying a property that needs work, conventional financing is typically the only realistic path.

When FHA Makes Sense — and When It Doesn’t
FHA is a strong fit when your credit score is below 680 and you can’t realistically qualify for competitive conventional pricing. It’s also the right tool when your down payment is tight and you need the flexibility of 3.5% to get into a home now rather than waiting years to save more. Borrowers recovering from past financial hardship — a previous bankruptcy discharged more than two years ago qualifies for FHA — often find this path opens doors that conventional lenders keep shut.
FHA makes less sense once your score climbs above 720 and you have at least 5%–10% to put down. At that point, the lifetime MIP obligation on FHA can cost you tens of thousands more than a conventional loan over the life of the mortgage. I’ve seen borrowers lock into FHA financing at 740+ scores purely out of familiarity with the program, then realize three years later they’re paying MIP that would have been eliminable on a conventional product. Refinancing corrects it, but you absorb closing costs twice.
FHA also struggles on competitive offers in seller’s markets. Some sellers — particularly those who’ve had FHA deals fall apart due to appraisal condition requirements — will favor conventional buyers. In tight inventory markets, that perception disadvantage is real. If you’re competing against multiple offers, a conventional pre-approval can carry more weight even if the financial terms are similar. For deeper guidance on managing debt obligations alongside a mortgage, the resource on debt consolidation loan pros and cons offers a useful framework for thinking through existing liabilities before you apply.
For borrowers evaluating their broader financial picture alongside a home purchase decision, understanding how closing unused credit cards affects your credit profile can matter more than people expect — especially when a few points separate you from FHA’s 3.5% threshold and a conventional loan at a lower rate.
Conclusion
The FHA loan versus conventional mortgage decision comes down to three numbers: your credit score, your down payment, and how long you plan to stay in the home. If your score is below 680 or your savings won’t cover 5% down, FHA gives you a viable path to ownership that conventional lending would effectively block. If you’re at 720 or above with a reasonable down payment, the lifetime MIP on FHA often costs more than the rate premium you’d pay on conventional — and the cancellable PMI makes the conventional path cleaner over time. Run both scenarios with your actual numbers before signing a loan estimate. The difference between choosing correctly and defaulting to the familiar program can be $20,000 to $40,000 over the life of a typical mortgage. That’s worth two hours of comparison shopping. If you’re also restructuring existing debt before applying, student loan refinancing strategies can free up the debt-to-income room that determines which mortgage tier you qualify for.
FAQ
Can I switch from an FHA loan to a conventional loan later?
Yes, through a conventional refinance. Once you have enough equity — typically 20% to avoid new PMI — refinancing into a conventional loan eliminates the FHA’s lifetime MIP. You’ll pay closing costs again (usually 2%–5% of the loan amount), so the math works best if you plan to stay in the home long enough to recoup those costs through lower monthly payments.
Does FHA or conventional offer lower interest rates?
FHA rates are often slightly lower in advertised form, but the total monthly cost including MIP frequently exceeds a conventional loan’s rate plus PMI for borrowers with scores above 700. Always compare the APR and total monthly payment — not just the interest rate — before concluding which product is cheaper.
What debt-to-income ratio do I need for each loan type?
FHA allows a back-end DTI (total monthly debt payments divided by gross income) up to 57% in some cases, though most lenders cap it around 50%. Conventional loans generally require a DTI at or below 45%, with some flexibility to 50% for borrowers with compensating factors like strong reserves or a high credit score.
Are FHA loans only for first-time homebuyers?
No. FHA loans are available to any borrower who meets the credit and income requirements, regardless of prior homeownership. However, FHA does require the property to be your primary residence — you can’t use FHA financing for investment properties or vacation homes.
How long does an FHA appraisal take compared to conventional?
Both typically take 7 to 14 business days in normal market conditions. FHA appraisals can add time if the appraiser notes condition issues that require repairs before the loan closes. That repair-and-re-inspection cycle can add one to three weeks to a transaction, which matters in time-sensitive deals.
