Financial decision
The gap looks trivial. Its effect on mortgage insurance pricing usually is not.
Conventional financing starts at 3% down for buyers who meet specific program rules, and at 5% down for everyone else. The extra two percentage points is real money — on a $400,000 home it is $8,000 — so it is worth knowing exactly what you get for it.
At a glance
The conventional minimum, available through programs such as HomeReady and Home Possible or standard 97% financing when at least one borrower is a first-time buyer.
The standard conventional minimum with no first-time-buyer restriction, no income cap, and access to the full range of property and occupancy types.
| Factor | 3% Down | 5% Down |
|---|---|---|
| Cash at closing | Lowest conventional option | $8,000 more on a $400k home |
| Mortgage insurance rate | Higher — 97% loan-to-value | Lower — 95% loan-to-value |
| First-time buyer required | Often yes | No |
| Income limits | Yes on HomeReady / Home Possible | None |
| Second homes and investment | Not eligible | Eligible at higher minimums |
| Time to cancel insurance | Longer | Shorter |
Two percentage points of down payment can move your mortgage insurance premium by more than the interest rate you spent three weeks shopping for.
Plain English first, then the rule as it is published, then what it means for your file.
“At least one borrower must be a first-time homebuyer when all borrowers are occupying the property and the LTV exceeds 95%.”
A first-time homebuyer means you have not owned a principal residence in the last three years — so a previous owner who has rented since can qualify again.
“Standard mortgage insurance coverage of 35% is required for LTV ratios of 95.01%–97.00%, and 30% coverage for 90.01%–95.00%.”
More coverage means a higher premium. This is why the monthly cost gap between 3% and 5% down is usually larger than the loan amount difference alone would suggest.
Waiting to save the extra 2% would take many months, you qualify under a low-down-payment program, and preserving cash reserves matters more than the premium.
You already have the funds, you do not meet first-time-buyer or income requirements, or you want the lower insurance premium and faster path to cancelling it.
Get both quotes with real premiums attached. If the break-even is under three years and you already have the cash, 5% usually wins. If saving it would delay you past a year, buying at 3% is rarely the wrong call.
Yes. On a one-unit principal residence, the entire down payment may come from an acceptable donor with a signed gift letter and a documented transfer.
Sometimes. FHA requires 3.5% down but prices its insurance by rule rather than by credit score, so it often wins below roughly 680 and loses above it.
Loan-level pricing adjustments do rise as loan-to-value rises, so expect a modest rate difference in addition to the insurance premium.
