Choosing between an FHA loan and a conventional loan is one of the most consequential decisions a buyer with a smaller down payment makes, yet it is often reduced to a slogan: FHA is for people with weaker credit, conventional is for everyone else. The reality is more nuanced. The two programs price mortgage insurance differently, treat credit scores differently, cancel their insurance differently, and follow different property and occupancy rules. For some buyers FHA is meaningfully cheaper for the entire time they own the home; for others it is the more expensive path by tens of thousands of dollars. This guide walks through every material difference using current 2026 rules and a worked cost comparison, so you can decide with numbers rather than reputation.
The short version: FHA tends to win for buyers with credit scores below roughly 680, very small down payments, or higher debt loads. Conventional tends to win for buyers with strong credit, at least 5-10% down, and a plan to hold the loan for many years, because conventional PMI can be cancelled while FHA mortgage insurance often cannot.
Down payment and credit score requirements
FHA loans are built for buyers who cannot meet conventional standards. The program allows a 3.5% down payment with a credit score of 580 or higher, and 10% down for scores between 500 and 579, although many lenders impose their own minimums of 600 to 640 because they carry the risk of a loan that later defaults. Conventional loans backed by Fannie Mae or Freddie Mac generally require a 620 minimum score, and the pricing is where the difference shows: a borrower at 620 pays far more for conventional financing than a borrower at 760, because the interest rate and the private mortgage insurance rate both scale steeply with credit score.
Down payment options on the conventional side are more varied than many buyers realize. Programs such as Fannie Mae HomeReady and Freddie Mac Home Possible allow 3% down for qualifying buyers, typically with income limits tied to the local area median, and many lenders offer standard 5% down conventional loans with no income limit. So the old claim that FHA is the only low-down-payment option is no longer accurate. What FHA still offers uniquely is flexibility for borrowers whose credit history is thin or damaged, because its insurance pricing does not vary by credit score the way conventional PMI does.
Mortgage insurance: the cost difference that decides most comparisons
Both programs require mortgage insurance when you put less than 20% down, and that insurance is the single largest driver of the cost gap. FHA charges two premiums: an upfront premium equal to 1.75% of the base loan amount, which most borrowers finance into the loan, plus an annual premium paid monthly. For a 30-year loan at or below the $726,200 base-loan threshold, the annual rate is 0.50% when the original loan-to-value is 95% or lower and 0.55% when it is above 95%. Shorter 15-year loans carry lower annual rates, from 0.15% to 0.40% at the same threshold.
Conventional PMI has no upfront premium in its standard monthly form, and its annual rate is not fixed by the government. Private insurers price it based on your credit score and loan-to-value ratio. For a borrower with a 760 score putting 5% down, PMI might run about 0.44% a year. For a borrower at 660-699 it might be about 1.06%, and for a borrower in the 620-659 range it can reach 1.50%. That structure produces the central insight of this comparison: FHA insurance is priced almost independent of your credit, so it is a bargain for weaker credit and a poor value for excellent credit.
A worked cost comparison on a $350,000 home
To make the difference concrete, consider a $350,000 purchase with 5% down, a $332,500 base loan, and a 30-year term. For illustration, assume an FHA rate of 6.4% and a conventional rate of 6.7%, reflecting the fact that FHA rates are often slightly lower than conventional rates for the same borrower. The FHA loan adds a $5,818 upfront premium to the balance, producing a principal-and-interest payment of about $2,116 plus roughly $138 a month in annual MIP, for a total of about $2,254 before taxes and insurance.
On the conventional side, principal and interest at 6.7% is about $2,145. Add PMI and the monthly total depends on credit: about $2,267 at a 760+ score, $2,333 at 700-759, $2,439 at 660-699, and $2,561 at 620-659. In this example, FHA is cheaper by roughly $79 a month at a 700-759 score, by about $185 a month at 660-699, and by about $307 a month at 620-659, while it is roughly equal to conventional at the very top credit tier. These are illustrations built on assumed rates, and real quotes will differ, but the pattern holds across market conditions: the lower your score, the more FHA saves you, and the higher your score, the more conventional catches up and then wins over time.
How long you pay mortgage insurance
The monthly comparison above only tells half the story, because the two kinds of insurance end at very different times. Conventional PMI can be requested for removal once your balance reaches 80% of the original home value, and federal law requires the servicer to terminate it automatically at 78%. A borrower who puts 5% down and makes only the required payments typically reaches 80% loan-to-value in roughly ten to twelve years, and sooner with extra payments or appreciation. After that, the insurance cost drops to zero.
FHA works differently. If your original loan-to-value ratio is above 90%, meaning you put down less than 10%, the annual MIP stays for the entire life of the loan. If you put down 10% or more, it ends after 11 years. Over a full 30 years, the 0.50% annual premium on a $332,500 loan adds up to roughly $50,000 before accounting for the declining balance, and that is on top of the financed upfront premium. This is why many FHA borrowers plan to refinance into a conventional loan once they have about 20% equity, which removes the insurance entirely, though it requires new closing costs and a rate that makes the refinance worthwhile.
Loan limits in 2026
Both programs cap how much you can borrow. The 2026 conforming loan limit for a one-unit property is $832,750 in most of the country, rising to as much as $1,249,125 in designated high-cost counties. FHA limits are tied to the same figures but set by county: the floor for a one-unit property is $541,287, which applies in lower-cost areas, and the ceiling is $1,249,125 in the most expensive markets. That means a buyer in a modest-cost county may find the FHA limit lower than the conventional limit, which matters for anyone shopping above roughly $540,000.
Loans above the conforming limit are jumbo loans, which are not eligible for purchase by Fannie Mae or Freddie Mac and follow stricter underwriting. If your target home price and down payment produce a loan near the top of the FHA limit for your county, check the exact figure for your location before choosing a program, because the difference between the two limits can force the decision for you.
Debt-to-income and underwriting flexibility
FHA has historically been more forgiving on debt-to-income ratios. The standard guideline allows a back-end ratio around 43%, but loans that receive an automated approval with strong compensating factors are routinely approved above 50%. Conventional loans processed through Fannie Mae or Freddie Mac automated systems commonly cap at 45%, with some approvals up to 50% for borrowers with strong credit and reserves. If a large car payment or student loan balance is pushing your ratio near the limit, FHA may approve a loan that conventional will not.
FHA also treats certain credit events more leniently. Waiting periods after bankruptcy and foreclosure are shorter than conventional, and manual underwriting is available for borrowers with limited credit history who can document rent and utility payment records. None of this means FHA is easy to qualify for, and lenders can and do apply their own overlays, but it is the program designed to accommodate borrower profiles that conventional automated underwriting tends to decline.
Property standards and appraisal differences
FHA appraisals evaluate not only value but also whether the home meets minimum property standards for safety, soundness, and security. Peeling lead-based paint in an older home, a failing roof, missing handrails, or a nonfunctional heating system can each stall an FHA closing until repaired. This protects the buyer, but it can also derail a purchase of a fixer-upper, and in competitive markets some sellers reject FHA offers because they expect delays or repair demands.
Conventional appraisals focus primarily on value and marketability, with fewer condition requirements, though a home with serious defects can still be flagged. FHA also requires that you occupy the home as your primary residence, typically within 60 days of closing and for at least a year. Conventional financing allows second homes and investment properties, at different down payment and rate levels, which makes it the only option if you are buying anything other than your main home.
Seller concessions, gifts, and closing costs
Both programs let sellers contribute toward your closing costs, but the limits differ. FHA allows seller concessions up to 6% of the sale price. Conventional limits depend on your down payment: 3% when you put down less than 10%, 6% when you put down between 10% and 25%, and 9% above 25%. In a slower market where you can negotiate concessions, FHA allows more room to roll closing costs into the seller’s side of the deal when your down payment is small.
Both programs permit gift funds from family for the down payment, with documentation requirements. FHA is generally broader about acceptable gift donors, including certain employers, unions, and charitable organizations. Whichever program you use, ask the lender for a full Loan Estimate and compare the total cash to close, not only the interest rate, because the FHA upfront premium is financed while conventional loans may carry higher origination or credit-related pricing adjustments that appear as upfront costs.
Assumability and refinancing flexibility
FHA loans are assumable, meaning a future buyer can take over your existing loan, subject to lender approval and qualification. In a higher-rate environment, that can be a genuine selling advantage if you locked a lower rate, because a buyer may prefer inheriting your 5% FHA loan to taking a new 7% loan. Most conventional loans are not assumable, so this option effectively exists only with FHA and VA financing.
FHA also offers a streamline refinance that reduces documentation and appraisal requirements when you refinance from one FHA loan to another and can show a net tangible benefit. That can be a low-friction way to capture a lower rate later. If you instead plan to move out of FHA into conventional to drop mortgage insurance, remember that you will go through full underwriting again, so your credit score, income, and home value at that time all matter.
Run your own scenario with the FHA Mortgage Calculator and the PMI Calculator, then compare the totals side by side.
Which loan fits which buyer
FHA is usually the better fit when your credit score is below about 680, when your down payment is close to the 3.5% minimum, when your debt-to-income ratio is high, or when you are recovering from a recent credit event. It is also a reasonable choice if you expect to move or refinance within five to seven years, because the long-term cost of lifetime mortgage insurance never fully materializes. Conventional is usually better when your score is 700 or higher, when you can put down 5% to 10% or more, when you plan to stay in the home a long time, or when you are buying a second home or investment property.
The strongest approach is not to pick a side in advance but to request quotes for both from at least two or three lenders, run the monthly and long-term costs, and factor in how long you realistically expect to hold the loan. A borrower who qualifies for both programs and expects to stay for fifteen years will often find conventional cheaper overall, even if FHA looks cheaper in the first year. A borrower who might move in five years may find FHA’s lower monthly cost wins outright.
Common mistakes when choosing between them
The first mistake is comparing only interest rates. FHA rates are often lower, but the upfront and annual mortgage insurance premiums can more than offset that advantage for a high-credit borrower, so the comparison must include the full monthly cost and the total cost over your holding period. The second mistake is assuming you can drop FHA mortgage insurance later without effort. Unless you put at least 10% down, removal requires a refinance, and a refinance depends on rates, closing costs, and your home value at that time.
The third mistake is ignoring the property. If you are drawn to a home that needs work, an FHA appraisal may require repairs before closing, which can be a dealbreaker with a seller who will not negotiate. The fourth is failing to check the loan limit for your county, and the fifth is neglecting to ask whether you qualify for a conventional low-down-payment program such as HomeReady or Home Possible, which can produce a better outcome than FHA for buyers whose incomes fall under the program limits.
The refinance-out strategy: when leaving FHA pays off
Many FHA borrowers treat the loan as a bridge: they use the low down payment and flexible credit standards to buy now, then refinance into a conventional loan once their situation improves. The refinance pays off when three conditions line up. First, your equity has reached at least 20% of the home’s current value, through paydown, appreciation, or both, so the new conventional loan needs no PMI. Second, your credit score has improved enough to qualify for competitive conventional pricing. Third, the interest rate available makes the closing costs worthwhile, which you can test with a break-even calculation.
The savings can be substantial. On a $332,500 FHA loan carrying roughly $138 a month in MIP, eliminating that premium saves about $1,660 a year, or $16,600 over ten years, before considering any change in the interest rate. Against that, a refinance typically costs two to five percent of the loan amount in closing costs. If you expect to keep the home well past the break-even point, the math is favorable. If rates have risen since you bought, however, giving up a lower FHA rate to escape MIP can cost more than it saves, so run both figures before committing.
How mortgage insurance affects what you can afford
Because mortgage insurance is part of your monthly housing payment, it counts toward the front-end debt-to-income ratio lenders use to size your loan. A payment that includes $190 a month of PMI leaves less room under a 28% housing cap than the same payment without it, which lowers the price you can afford by roughly the amount that premium would otherwise support in loan principal. On a typical loan, each $100 of monthly mortgage insurance reduces affordable loan size by around $15,000.
This is one reason the cheaper insurance program can also be the program that lets you buy more house. A buyer at a 640 score who would pay $415 a month in conventional PMI but only $138 in FHA MIP frees up about $277 a month of qualifying payment, which can translate into a loan roughly $40,000 larger under FHA than under conventional at the same income. Whether that extra buying power is worth taking is a separate question, but it illustrates that the choice affects qualification as well as cost.
