How to Weigh a 30-Year Fixed FHA Loan Against a Conventional Loan

The Quick Read: The choice comes down to credit, down payment, and how long you plan to keep the loan. FHA tends to win when credit is lower or cash is tight. Conventional tends to win when credit is strong and the down payment is larger, because its mortgage insurance can come off. Run both against your own file before picking one.

What Is the Real Difference Between the Two Loans?

An FHA loan is made by a private lender and insured by the Federal Housing Administration. The FHA does not lend. A conventional loan is simply one that sits outside a government program. Both can be a 30-year fixed loan, so the payment structure looks the same. What differs is who qualifies, what the insurance costs, and how long the insurance lasts.

The CFPB’s FHA loan page puts the tradeoff plainly. FHA loans allow lower credit scores and small down payments. They tend to cost more for borrowers with good credit and a medium down payment, and they can be a more affordable option for borrowers with lower scores or less cash.

That is the whole article in one paragraph. The rest is how to test it on a real file.

Key Terms Defined

FHA loan: A mortgage made by a private lender and insured by the Federal Housing Administration, which protects the lender if the borrower defaults.

Conventional loan: A mortgage not backed by a specific government program.

Mortgage insurance premium (MIP): The FHA insurance cost, made up of an upfront premium and an annual premium billed monthly.

Private mortgage insurance (PMI): Insurance on a conventional loan, generally required when the down payment is under 20%.

Loan-to-value (LTV): The loan balance divided by the home’s value or price.

Debt-to-income (DTI) ratio: Your monthly debts divided by your gross monthly income. Lenders look at a housing ratio and a total ratio.

Step 1: Start With Credit and Down Payment

Credit score and down payment decide most of the outcome, so test them first.

Across the wholesale programs Lendmire places FHA files with, FHA allows financing up to 96.5% of the price. That means a 3.5% minimum investment, available from a decision score of 580. HUD’s own rules reach below that to a 500-579 tier with 10% down, but the lenders in Lendmire’s network start at 580. Lenders can also set tougher floors than HUD, so one lender’s cutoff is not another’s. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Conventional loans generally ask for stronger credit. Some conventional programs allow low down payments, but the better pricing usually goes to borrowers with higher scores and more equity. Programs aimed at low-down-payment conventional buyers often carry income limits.

The test: if your score sits near the bottom of the range lenders accept, FHA is likely the open door. If your score is strong and you can put down a meaningful share, price both loans before assuming FHA is cheaper. The CFPB says it often isn’t for that buyer.

Step 2: Check Your Debt Ratios

How much of your income goes to housing and debt matters on both sides, but FHA is usually more forgiving.

On the FHA files Lendmire arranges, the base ratio pair is 31/43. That is housing cost over income, and total debt over income, with no compensating factors. Documented compensating factors can stretch that to 40/50 at the top tier. Most files are decided by the automated underwriting finding, not by the base pair alone.

Compensating factors are things like stable income, cash reserves, or a low payment shock. They have to be documented, not described. A borrower who says they have savings but cannot show statements gets no credit for it.

Conventional lenders also use automated underwriting. Their ratio room varies by lender and by file strength. A high ratio paired with a lower score is where FHA tends to pull ahead.

Step 3: Price the Insurance, Not Just the Loan

This is where most comparisons go wrong. Two loans can look alike until the insurance is added.

FHA charges two premiums. The upfront premium is 1.75% of the base loan, and it is usually financed into the balance. That raises the amount you owe and the interest you pay over time. The annual premium is billed monthly. In the Lendmire network it runs between 0.15% and 0.75% of the balance, depending on term, loan amount and LTV. HUD cut the annual premium for most new borrowers in Mortgagee Letter 2023-05, and the tiers are laid out in that letter.

Conventional PMI applies only when the down payment or equity is under 20%. It costs nothing at 20% or more. That is a real advantage for a buyer with a larger down payment.

Neither premium is a price quote here. Your Loan Estimate shows the actual cost line by line.

How Long Does the Insurance Last?

The insurance timeline is the strongest lever in the whole comparison.

On a 30-year FHA loan above 90% LTV, the annual premium lasts for the term. At or below 90% LTV, it ends after eleven years. The Congressional Research Service’s FHA overview describes the 11-year rule at 90% LTV or lower. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Conventional PMI works differently. Under the Homeowners Protection Act, servicers must terminate PMI automatically when the balance is first scheduled to reach 78% of the original value, provided the borrower is current. Borrowers can also request cancellation at 80%, subject to conditions like a good payment history. The CFPB’s HPA procedures manual lays out both thresholds. The Federal Reserve’s supervisory manual notes that high-risk loans are exempt from these cancellation rules.

One common mistake: assuming FHA insurance drops off at 78% like PMI. It does not. The 78% rule covers private mortgage insurance, not FHA.

Step 4: Think About How Long You’ll Stay

Duration decides whether a small monthly difference becomes a large total one.

Picture a buyer who expects to move within a few years. The long insurance tail matters less to that buyer, because they will sell before it adds up. The low entry requirement may matter more.

Now picture a buyer who plans to stay for decades. On a low-down-payment FHA loan, the premium sticks for the term. A conventional loan with PMI sheds that cost once equity builds. For this buyer, conventional can be cheaper in total even if it looked slightly worse at the start.

Run the same home through both loans, then compare three things on the Loan Estimates side by side: the monthly payment including insurance, the cash needed to close, and how long the insurance lasts.

Where the General Rule Breaks

The simple rule, FHA for weaker files and conventional for stronger ones, has exceptions.

A large down payment with good credit. The CFPB notes FHA tends to cost more here. At 10-15% down with strong credit, conventional often comes out ahead.

A very low down payment with strong credit. The picture can flip. Low-down conventional programs exist, and FHA’s insurance may or may not beat PMI for that score. Price both.

A higher-priced home. FHA limits are set by county and change every year, so county loan limits apply. Above the FHA limit, FHA is unavailable and conventional or jumbo takes over. HUD announces the limits annually and ties them to the conforming loan limit.

A multi-unit home. FHA allows one to four units, and limits rise with unit count. Owner-occupancy still applies. You must live in the property as your principal residence. Second homes and rental properties are generally conventional-only.

A home needing repairs. The FHA appraisal does two jobs. It sets market value, and it checks the home against HUD’s minimum property requirements, which exist so insured loans are secured by property that is safe, sound and secure. HUD has drafted changes to those requirements in its modernization drafting table, so check the current handbook rather than assuming old rules. The appraisal is not a home inspection. But repairs it flags can hold up a closing. HUD Handbook 4000.1 governs FHA policy, and its text prevails over other guidance.

Past credit events. HUD sets waiting periods: two years from a chapter 7 discharge and three years from a foreclosure. Those are HUD rules, not a promise from any lender.

Older FHA loans. Loans originated before mid-2013 followed older cancellation rules.

Can You Start With FHA and Move to Conventional Later?

Often yes, and it is the practical exit for many borrowers who put little down.

Refinancing out of FHA into a conventional loan ends the FHA insurance once the FHA loan is paid off. The catch is that the new loan has to qualify on its own. That means enough equity, a score a conventional lender will accept, and a property that appraises. A drop in credit or in value between now and then can block the move.

If you stay in FHA, there are also FHA-to-FHA paths. The Streamline refinances an existing FHA loan with no appraisal and a limited credit review, but it requires a net tangible benefit, and the premium continues. The FHA rate-and-term refinance with an appraisal reaches 97.75% on a principal residence occupied for the previous twelve months. The FHA cash-out reaches 80% LTV on a home owned and occupied for 12 months before the case number. Lendmire’s piece on weighing FHA cash-out against conventional goes into that choice. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.

What the Lender Looks For

• Credit history and decision score, including any recent events.
• Documented income and employment that support the ratios.
• Cash for the minimum investment, with sourced statements.
• Gift or seller help, where allowed. On FHA purchases, seller or interested-party contributions reach 6% of the price.
• A non-occupant co-borrower, if needed. FHA allows one.
• An appraisal that supports value, and on FHA, condition.

Documentation gaps cause more delays than the program choice does. Gather statements and income records before you apply.

Common Mistakes

Comparing only the headline numbers. The insurance, the financed upfront premium, and the time horizon change the answer.

Assuming FHA is always more affordable. The CFPB says it is not, for stronger borrowers.

Assuming FHA is a government loan. Private lenders make it. The agency insures it.

Assuming HUD’s minimums are every lender’s minimums. Lenders can add overlays, so a score that works at one lender may not at another.

Skipping the appraisal angle. An FHA appraisal flags condition issues that a conventional one may treat differently, depending on the investor.

A Simple Way to Decide

Work through five tests in order:

1. Credit and down payment. Lower score or thinner cash points to FHA. Strong score and larger down points to conventional.

2. Payment comfort. Compare the full monthly payment with insurance on both Loan Estimates.

3. Insurance over time. Note whether the premium lasts the term or can be cancelled.

4. Years you will keep the loan. The longer the stay, the more cancellable insurance helps.

5. Property and limit fit. Confirm the county loan limit and the home’s condition.

If the tests disagree, the time horizon usually breaks the tie. When the margin is thin, FHA with a planned refinance can bridge the gap.
