Conventional vs FHA loan comes down to one question most buyers never think to ask: do you want the easier approval today, or the cheaper mortgage over the next ten years? The honest answer depends on your credit score, and on a mortgage insurance rule that quietly changes your total cost more than the interest rate does.
What's Inside
Conventional vs FHA loan is the first real fork in the road for most first-time buyers, and the common shorthand, "good credit means conventional, weak credit means FHA," is true often enough to be dangerous, because it skips the one factor that actually decides your total cost over a decade: how each loan handles mortgage insurance.
This guide walks through the real side-by-side differences, the insurance rule that matters more than the rate, and a worked example showing what each loan actually costs you over time.

Side-by-Side Comparison

| Factor | FHA loan | Conventional loan |
|---|---|---|
| Minimum credit score | 580 (3.5% down) or 500 (10% down) | 620 typical, some lenders to 600 |
| Minimum down payment | 3.5%-10% | 3%-5% for first-time buyer programs |
| Mortgage insurance | Upfront 1.75% + annual; often life of loan | PMI only if under 20% down; cancels at 78-80% LTV |
| Maximum DTI | Up to 43-50%, sometimes higher with compensating factors | 36-45% typical, up to 50% with strong credit/reserves |
| Property use | Primary residence only | Primary, second home, or investment property |
| Property condition standards | Stricter safety/habitability requirements | More flexible |
The Mortgage Insurance Difference That Matters Most
This is the single biggest factor most buyers underweight. FHA loans charge an upfront mortgage insurance premium (MIP) of 1.75% of the loan amount, plus an annual premium, and for most borrowers who put down less than 10%, this premium lasts for the entire life of the loan, not just until you build equity. Conventional loans only charge private mortgage insurance (PMI) if you put down less than 20%, and that PMI cancels automatically once you reach roughly 20% equity, typically 7 to 10 years into a standard amortization schedule.
Why this outlasts the rate difference
FHA loans often advertise a slightly lower headline interest rate than conventional loans. But once you add MIP that never cancels, the FHA loan's true annual percentage rate frequently ends up costing more over time than a conventional loan with cancelable PMI, especially for borrowers with credit scores above 680-720 who qualify for competitive conventional pricing.
Loan Limits
As of 2026, FHA loan limits for a single-family home range from about $541,287 in most areas up to $1,249,125 in high-cost counties. Conventional conforming loan limits start higher, around $832,750 in most areas, but converge to the same $1,249,125 ceiling in high-cost markets. In other words, if you are buying in an expensive market, both loan types can lend you the same maximum amount, credit score and mortgage insurance become the deciding factors, not the ceiling itself.
Which Is Better for Bad Credit
FHA is generally the more forgiving option below a 620 credit score, since it accepts scores as low as 580 with 3.5% down, or even 500 with 10% down. If your score sits between 500 and 619, FHA is often your only realistic path to a low-down-payment mortgage right now. See the fuller picture in how to buy a house with bad credit.
Which Is Better for a Fixer-Upper
Conventional loans are generally the more flexible choice here. FHA loans require the property to meet specific safety and habitability standards during appraisal, which can complicate purchasing a home with significant deferred maintenance, and can also make sellers in competitive multiple-offer situations less receptive to an FHA-financed buyer.
FHA Now, Refinance to Conventional Later
- Buy with FHA if your credit or savings do not yet clear conventional thresholds, accepting the mortgage insurance cost as the price of getting into the market sooner.
- Build equity and credit over the following years through regular payments and responsible credit use.
- Refinance into a conventional loan once you reach roughly 20% equity and your credit score improves, eliminating the FHA MIP and often securing a better rate. See how to refinance your mortgage to lower payments.
This is one of the most common paths first-time buyers actually take, and a completely reasonable one, since it prioritizes getting into homeownership now over waiting years to qualify for the theoretically cheaper option.
A Worked Cost Comparison
On a $300,000 home with a 660 credit score, illustrative numbers might look like this: FHA at 3.5% down means roughly $10,500 down, plus a $5,075 upfront MIP (often rolled into the loan), plus an ongoing annual MIP that continues for the life of the loan in most cases. A conventional loan at 5% down means roughly $15,000 down, plus PMI that runs until the loan reaches 20% equity, then disappears entirely. Over a 10-year hold, the conventional loan's PMI often costs meaningfully less in total than FHA's life-of-loan MIP, even though the FHA loan needed less cash upfront.
Common Mistakes (and How to Dodge Them)
- Choosing based on the interest rate alone. FHA's slightly lower headline rate can be erased by MIP that never cancels.
- Forgetting to plan a future refinance. If you start with FHA, build a mental checkpoint to refinance once you hit 20% equity and better credit.
- Assuming FHA is always cheaper for lower credit. Run both scenarios; a conventional loan with a slightly higher rate can still beat an FHA loan's total insurance cost in some cases.
- Overlooking property condition risk with FHA on a fixer-upper. Confirm the property will pass FHA's appraisal standards before you fall in love with a home that needs work.
- Not comparing multiple lenders. Both FHA and conventional rates and fees vary meaningfully between lenders. A single quote rarely reflects your best available option.
Frequently Asked Questions
What credit score do I need for a conventional loan versus an FHA loan?
FHA loans accept credit scores as low as 580 with 3.5% down, or 500 with 10% down. Conventional loans typically require a minimum score of 620, though some lenders accept scores as low as 600, and borrowers with scores above 740 receive the most favorable rates and terms.
Is FHA or conventional mortgage insurance more expensive?
FHA mortgage insurance includes an upfront premium of 1.75% of the loan amount plus an ongoing annual premium that typically lasts for the life of the loan if you put down less than 10%. Conventional PMI only applies if you put down less than 20%, and it cancels automatically once you reach about 20% equity, which often makes it cheaper over a longer hold period even if the FHA rate looked lower initially.
What are the FHA and conventional loan limits in 2026?
FHA loan limits for a single-family home range from about $541,287 in most areas to $1,249,125 in high-cost counties. Conventional conforming loan limits start around $832,750 in most areas but reach the same $1,249,125 ceiling in high-cost markets. Both loan types can lend the same maximum amount in expensive areas.
Can I use an FHA loan to buy an investment property?
No. FHA loans are restricted to primary residences that you occupy within 60 days of closing, with limited exceptions for multi-unit properties where you live in one unit and rent the others. Conventional loans can be used for a primary residence, a second home, or a pure investment property.
Should I start with an FHA loan and refinance to conventional later?
Many first-time buyers do exactly this: use FHA to get into homeownership sooner with a lower down payment and more flexible credit requirements, then refinance into a conventional loan once they reach roughly 20% equity and their credit has improved, eliminating the FHA mortgage insurance and often securing a better rate.
Which loan is better for buying a fixer-upper?
Conventional loans are generally more flexible for a fixer-upper, since FHA loans require the property to meet specific safety and habitability standards during appraisal, which can complicate homes needing significant repairs. Sellers in competitive situations may also be less receptive to FHA-financed offers for this reason.
Choose the Loan That Fits Your Timeline, Not Just Today
Conventional vs FHA loan is not really a question of which one is universally better. It is a question of whether you are optimizing for qualifying today or minimizing cost over the next decade. Run both scenarios with real numbers for your credit score and target home price, and if FHA gets you in the door sooner, treat refinancing to conventional later as part of the plan, not an afterthought.
