Conventional mortgage-insurance plan funded with one lump-sum premium at closing instead of a standard monthly premium.
Single-premium mortgage insurance is a conventional private mortgage-insurance plan funded with one lump-sum premium at closing instead of a standard monthly PMI premium.
Single-premium MI can reduce the recurring mortgage payment, but it moves more cost to the beginning of the loan. The premium may be paid from borrower funds or supported through another permitted transaction structure. If any amount is financed, the borrower also pays interest on that added balance.
The expected holding period is critical. A borrower who sells or refinances soon after closing may not remain in the loan long enough for monthly savings to offset the upfront cost. Refund rights, if any, depend on the policy and should not be assumed.
Borrowers encounter single-premium MI while comparing conventional mortgage-insurance options before rate lock. The lender should show the premium in the Loan Estimate’s closing-cost details and reflect any permitted financing in the loan amount and cash-to-close calculation.
At closing, the borrower should confirm three points on the final disclosure:
A borrower compares these illustrative conventional PMI options:
| Option | Upfront premium | Monthly premium |
|---|---|---|
| Monthly PMI | $0 | $110 |
| Single-premium PMI | $4,400 | $0 |
Ignoring financing cost and changes in the monthly PMI amount, the simple break-even period is 40 months: $4,400 / $110. If the borrower expects to refinance in two years, the upfront structure may cost more over that period. If the borrower keeps the loan much longer, the comparison may favor the single premium. Actual analysis must include financing interest, cancellation timing, and policy terms.
| Question | Why it matters |
|---|---|
| Is the premium refundable? | Early payoff may not return unused cost |
| Is any premium financed? | Financing raises principal and interest expense |
| What is the monthly-plan alternative? | The borrower needs a comparable baseline |
| When could monthly PMI be canceled? | A shorter PMI horizon weakens the case for a large upfront premium |
| How long will the loan likely remain outstanding? | Holding period drives the break-even comparison |
Single-premium MI differs from Monthly Mortgage Insurance because monthly MI spreads premium collection over recurring payments.
It differs from Split-Premium Mortgage Insurance because split premium combines a smaller initial charge with an ongoing monthly charge.
It also differs from Upfront Mortgage Insurance Premium (UFMIP). Single-premium MI is a conventional private-insurance plan; UFMIP is the FHA program’s upfront insurance charge.
