Should You Choose a Conventional or FHA 30-Year Fixed?

The Quick Read: It depends on three things: your credit profile, your down payment, and how long you expect to keep the loan. FHA usually fits a thinner credit file or a small down payment. Conventional usually costs less over time for a borrower with strong credit and real equity, because its mortgage insurance can be removed. Both can be a 30-year fixed, so the term is not what separates them.

What Are You Actually Comparing?

A 30-year fixed describes the term and the payment structure. FHA and conventional are the programs wrapped around it. Same term, different rules about credit, down payment, ratios, and mortgage insurance.

An FHA loan is insured by the federal government. A conventional loan follows investor guidelines, usually Fannie Mae or Freddie Mac. Across the wholesale programs Lendmire places FHA files with, the pattern is consistent: FHA widens who can qualify, and conventional rewards borrowers who already look strong on paper.

The comparison that matters is total monthly cost over the years you will actually hold the loan. Not the headline interest rate alone.

How Do the Two Loans Compare Side by Side?

FHA is the more flexible door; conventional is the cheaper one for strong files. FHA loosens credit and down payment. Conventional rewards credit and equity with insurance that can end.

Within Lendmire’s wholesale network, FHA starts at a 580 decision score. HUD itself has a lower tier for scores of 500 to 579, but the network does not reach below 580. Some lenders also set a higher floor than HUD does.

How Does Mortgage Insurance Differ?

FHA charges two premiums; conventional charges PMI that can fall away. This is the biggest cost gap between the loans, and the one borrowers most often misjudge.

On FHA, the upfront premium is 1.75% of the base loan, and it is typically financed into the balance. The annual premium runs between 0.15% and 0.75% of the balance, depending on term, loan amount, and LTV. On a 30-year loan above 90% LTV, the annual premium lasts for the full term. At 90% LTV or below, it ends after eleven years. HUD trimmed annual premiums in a 2023 announcement, so older comparisons you find online may overstate the cost.

Conventional PMI applies when you put down less than 20%. It is priced by credit score and down payment, so a strong borrower pays less. The CFPB explains that PMI protects the lender, not you, and that the requirement usually applies when refinancing with under 20% equity too.

Here’s the catch for FHA: with a small down payment, the premium typically stays for the life of the loan. The only way out is to refinance. Conventional PMI, by contrast, can be requested off at 80% of the original value and ends automatically at 78% if you are current. Those protections come from federal law, and the Federal Reserve’s supervisory manual notes the rules do not apply to high-risk loans. Lender-paid PMI is a different animal: the borrower cannot cancel it, and it usually means a higher interest rate.

Which Loan Fits Which Borrower?

Match the loan to your profile. A few common profiles and the usual lean:

• Score near 580 to 640, small down payment. FHA usually leans ahead here. Conventional pricing for this profile often gets expensive, and FHA premiums are not priced by credit score.
• Score well above 700, 10% to 20% down. Conventional usually wins, mainly because PMI is cheaper and can end.
• High score, 3% to 5% down. This one is close to a toss-up, so price both. PMI at low down payments still adds up, and FHA’s flexibility may not matter if your file is clean.
• Higher debt-to-income ratio. FHA often stretches further. The base ratios are 31/43, and documented compensating factors can reach 40/50 at the top tier. The automated finding governs most files.
• Staying in the home a short time. Insurance duration matters less, so upfront cost carries more weight.
• Staying a long time with a small down payment. The lifetime FHA premium matters a great deal, so plan on a later refinance or lean conventional if you qualify.

Honest uncertainty: a borrower in the middle on credit and down payment can land either way. The only reliable method is to compare two Loan Estimates for the same home and look at the total monthly payment, including insurance.

A Decision Order That Works

Check these in sequence:

1. Credit. Below a 580 decision score, the FHA programs Lendmire places files with are out of reach, and conventional is likely out too. Fix the file first.

2. Down payment. Under 20% means mortgage insurance on both loans. How much under changes which insurance is cheaper.

3. Debt-to-income. If ratios are tight, FHA’s flexibility may decide it.

4. Time horizon. The longer you hold the loan, the more removable PMI is worth.

5. Property and occupancy. FHA is for a principal residence, one to four units. If the home is not your primary residence, FHA is off the table. An FHA appraisal also checks the home against HUD’s property standards, not just value, so a house needing major repairs may struggle.

What About Loan Limits?

FHA loan limits are set by county and change every year. HUD publishes them annually, so check the current limits for your county. Conventional loans follow separate conforming limits set by the FHFA. If your needed loan exceeds the FHA limit where you are buying, conventional may be your only fit. In some counties the reverse is true.

Can You Leave FHA Later?

Yes, often, but it is a plan, not a promise. Many FHA borrowers refinance into conventional once they have built enough equity and improved their credit. That removes FHA’s annual premium, since conventional PMI is not charged once the loan is at or below 80% LTV.

Whether it works depends on your credit, your equity, and market conditions at that time. A refinance also carries its own costs, so the savings have to outrun them. If you are still on FHA and staying put, an FHA Streamline refinances an existing FHA loan with no appraisal and a limited credit review, but the premium continues. Lendmire’s piece Should You Choose FHA Cash-Out Over Conventional With Lower Credit? covers the equity-access side of that decision.

Practitioner pattern: borrowers who choose FHA with a clear exit plan tend to be happier than those who choose it by default. Borrowers who never price conventional often discover later that they qualified.

Common Mistakes to Avoid

• Comparing rates only. A lower rate with lifetime insurance can cost more than a slightly higher rate with removable PMI.
• Believing insurance protects you. It protects the lender on both loans.
• Assuming 20% down is required. You need it only to avoid conventional PMI on a purchase. FHA carries its own premiums regardless.
• Assuming zero-down FHA exists. The minimum investment is 3.5% at a 580+ score.
• Assuming PMI rules cover FHA. Federal PMI cancellation rights apply to conventional PMI, not FHA premiums.
• Skipping the second quote. Choosing FHA by default without pricing conventional is the most common miss. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Seller and interested-party contributions can go up to 6% of the price on FHA, and a non-occupant co-borrower is allowed. Both can help a borderline file.

Key Terms Defined

PMI: Private mortgage insurance, required on most conventional loans with less than 20% down, and it protects the lender.

MIP: The FHA mortgage insurance premium, charged as an upfront amount and an annual amount.

LTV: Loan-to-value, the loan balance as a percentage of the home’s value or price.

Decision score: The credit score a lender uses to underwrite the loan.

Loan Estimate: The standard form that lets you compare costs from different loans side by side.

Next Steps

Gather recent pay records, bank statements, and ID, and decide how long you expect to hold the home. Then request Loan Estimates on both programs for the same property.

If you are buying a home and want to see whether FHA loan programs fit your file, Lendmire can help you compare the options and what each one asks of the file. Program figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend.
