How Much Cash a Strong-Credit Buyer Needs on a Conventional Loan vs FHA

The Quick Read: The gap in down payment between the two loans is small, about half a percentage point of the price at the minimums. The bigger differences show up in who qualifies for the lowest conventional down payment, how mortgage insurance is charged, and how long it lasts. Conventional tends to suit buyers who qualify for its low-down-payment path and want insurance that can end. FHA tends to suit buyers who want one clear path to maximum financing, including on a two- to four-unit home.

Strong credit changes less about your minimum cash than most buyers expect. The program sets the maximum loan-to-value ratio, and that ratio sets your down payment. Credit mostly changes what you pay for, such as the cost of conventional mortgage insurance, and not how much you must bring.

Side-by-Side

Everything in the FHA column is subject to lender guidelines and full file review. Nothing here is a commitment to lend.

What “Cash Needed” Actually Includes

The down payment is only one bucket. Think of three.

1. Due at closing. The down payment, lender and third-party charges, prepaid items such as interest and the first insurance premium, and escrow deposits for taxes and homeowners insurance.

2. Financed. On FHA, the upfront mortgage insurance premium is usually added to the loan balance. You can also pay it in cash.

3. Kept in reserve. Money you hold after closing for repairs, moving and an emergency cushion.

Most buyers budget the first bucket and forget the third. Run both. A buyer who spends every dollar to reach the lowest down payment starts the first month with no cushion.

How the Two Down Payments Compare

On FHA, the minimum investment is 3.5% of the lesser of the price or the appraised value. A low appraisal raises your cash need on either loan. The financed premium does not reduce the down payment, because the down payment is figured on the base amount.

The FHA rule is set by HUD’s minimum decision credit score guidance. A score of 580 or higher is eligible for maximum financing. HUD allows scores down to 500 with a lower maximum, but the wholesale programs Lendmire places FHA loans with start at 580. A strong-credit buyer is nowhere near that line.

Conventional is less uniform. Fannie Mae’s eligibility matrix shows a 97% maximum on one-unit fixed-rate purchases, and 95% on adjustable-rate loans and on two- to four-unit homes. That 97% option is not open to everyone. Fannie Mae’s 97% LTV FAQ limits it to HomeReady purchases and standard purchases with at least one first-time buyer. It also requires a fixed-rate loan with a term up to 30 years, and it runs through automated underwriting. High-balance loans are not eligible. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Picture a repeat buyer with excellent credit and an income above the HomeReady limit. That buyer generally cannot get the 3% path on a standard loan. The cash need rises above the FHA minimum, and the exact figure depends on the program and file. Credit score alone does not unlock 97%.

How Strong Credit Changes the Math

Strong credit moves cost, not the minimum. Here is how.

On conventional loans, private mortgage insurance and loan-level pricing adjust by credit score and leverage. A higher score generally means cheaper insurance. This is the structural reason a strong-credit buyer often finds conventional less expensive month to month.

On FHA, the annual premium is set by loan term, loan amount and LTV. It does not move with your score. Across the wholesale programs Lendmire works with, that annual premium runs between 0.15% and 0.75% of the balance. The upfront premium is 1.75% of the base loan, per HUD Mortgagee Letter 2023-05.

Here’s the catch. The 1.75% upfront premium is financed, so it does not raise your closing-day cash. It does raise the loan balance. A conventional buyer usually has no comparable item at closing, because the insurance is built into the monthly cost.

Strong credit also helps with reserves. A buyer who qualifies for cheaper conventional insurance may choose to keep more cash liquid instead of piling extra into the down payment. That is a judgment call, and both sides are defensible.

When Conventional Is the Better Fit

Conventional usually wins on total cost over time for a buyer with strong credit and a standard one-unit home. Three conditions point that way.

• You qualify for the low-down-payment path. A first-time buyer or HomeReady file can reach 3% down, which undercuts the FHA minimum.
• You expect to hold the loan for years. Conventional mortgage insurance can be cancelled. Fannie Mae’s PMI overview notes that PMI is usually required with under 20% down, and that FHA mortgage insurance works differently and may involve refinancing to remove it.
• You can put down more. As leverage drops, conventional insurance gets cheaper and eventually drops off. FHA’s annual premium stays in place for the term on a thirty-year loan above 90% LTV. At or below 90% LTV it ends after eleven years.

The tradeoff: conventional underwriting leans on the automated findings, and the lowest leverage comes with conditions. A buyer who misses those conditions can find the cash need higher than expected. Lendmire’s piece Should a Strong-Credit Buyer Skip FHA for a Conventional Loan? walks through that decision in more detail.

When FHA Is the Better Fit

FHA is not only for weak credit. Maximum financing starts at 580, and a strong-credit buyer can use it. It fits several situations.

• You do not meet the conventional 97% conditions. FHA offers 96.5% financing without a first-time-buyer or income test. Owner-occupancy is required.
• You are buying a two- to four-unit home and living in one unit. FHA allows 96.5% on one to four units. Conventional is lower on two to four units per the matrix.
• Your ratios are tight. The FHA base pair is 31/43. Documented compensating factors can stretch it to 40/50 at the top tier, though the automated finding governs most files.
• You need help from others. FHA allows a non-occupant co-borrower. Seller or interested-party contributions can reach 6% of the price, and they go toward closing costs rather than the minimum investment. Gift funds need a gift letter and donor documentation.
• You will likely refinance later. If you plan to refinance within a few years, the long life of the FHA annual premium matters less.

The tradeoff: the annual premium and the financed upfront premium add up over time, and neither depends on your score. For a buyer with excellent credit, that can make FHA cost more over a long hold than conventional.

Where Files Slip on Cash

Most surprises come from the same few places.

• The appraisal. Both loans size the down payment off the lesser of price or value. A low appraisal means more cash, or a renegotiation.
• Source documents. Bank statements, gift letters and donor records get reviewed on both loans. Funds that appear suddenly and cannot be traced cause delays.
• Prepaids and escrows. These move with the closing date and your tax and insurance setup. An early estimate is not the final number.
• Treating the minimum as the plan. Reserves and moving costs sit outside the loan. Count them.

Because this is a consumer mortgage, you receive a Loan Estimate and later a Closing Disclosure. Compare the cash-to-close line on each against your budget.

A Balanced Verdict

If you are a first-time buyer with strong credit, conventional at 3% down often looks better. The cash need is a hair lower than FHA, and the insurance is cancellable. If you are a repeat buyer above the HomeReady income limit, the gap narrows or flips, and FHA’s 3.5% may be the lower cash path. If you are buying a small multiunit home to live in, FHA’s one-to-four-unit leverage matters.

So the real question is not credit score. It is which conditions you meet, how long you will hold the loan, and how much cash you want left after closing. Ask for both options on the same property and compare the cash-to-close, the financed amount and the insurance terms side by side.

Key Terms Defined

Minimum required investment: the FHA down payment, set at 3.5% of the lesser of price or appraised value.

Loan-to-value (LTV): the loan amount divided by the lesser of price or appraised value.

Upfront mortgage insurance premium: the one-time FHA charge of 1.75% of the base loan, usually financed.

Private mortgage insurance (PMI): conventional insurance, usually required with less than 20% down, and cancellable.

Prepaids: costs paid at closing for items that cover a future period, such as interest and the first insurance premium.

Reserves: money you hold after closing, outside the loan.
