Recast vs Reappraisal: Two Ways to Kill PMI
Mortgage insurance is charged because the lender thinks the loan is risky relative to the house. Two things can change that opinion: paying the balance down (a recast, or any principal reduction) or demonstrating that the house is worth more than the original valuation said (a reappraisal). They are different levers on the same ratio, and the cheaper one depends entirely on which side of the fraction is the problem.
The short answer
If you have cash and your loan-to-value is just above 80%, a principal reduction is usually the cheaper route: a few hundred dollars of recast fee against $400 to $800 for an appraisal, plus a faster process.
If your loan-to-value is well above 80% and the local market has risen sharply, an appraisal is often the only realistic route — because closing the gap with cash could take six figures.
What has to change
Loan-to-value is the balance divided by the value. Conventional loans generally allow a borrower to request PMI removal at 80% of the original value, and require automatic termination at 78% on the original amortisation schedule.
That distinction matters: many servicers will consider a request based on the *current* value only if you can document it, and documenting it usually means paying for an appraisal. Paying the balance down needs no documentation at all — the number is already on the statement.
The principal-reduction route
A $400,000 house with a $328,000 balance sits at 82% loan-to-value — above the line, which is why PMI is being charged. Recasting $40,000 takes the balance to $288,000, or 72%, comfortably below the threshold.
The cost is the recast fee, typically $150 to $500, and the interest lag while it processes. The benefit is twofold: the payment falls and, once you request removal, the PMI charge stops.
One caveat that trips people up: the recast does not remove PMI by itself. It changes the ratio; the removal is a separate request, with its own conditions, and some servicers require the loan to have been current for a period or require a new valuation before granting it.
The reappraisal route
If the local market has moved, an appraisal can do the same job without any cash. A $400,000 house that now appraises at $460,000 takes a $328,000 balance from 82% to 71% — PMI eligible for removal, with no principal payment at all.
The costs are an appraisal fee, typically in the $400 to $800 range depending on market and property type, plus the risk that the appraisal comes in low and the fee is spent for nothing. Some servicers will only accept an appraisal from their own panel, and some will not accept a value-based request at all until the loan is a certain age.
Choosing between them
Use the principal route when: you were going to apply a lump sum anyway, the gap is small, or your market is flat and an appraisal is unlikely to help. It also has the side benefit of lowering the payment, which the appraisal route does not.
Use the appraisal route when: the market has clearly risen, you would rather keep the cash, or the gap is wide. A 15-point gap on a $400,000 house is $60,000 of principal — money that an appraisal might save you entirely.
Use both when: the appraisal alone does not quite get you there, but a modest principal payment plus a strong appraisal does. That combination is common and is worth pricing before deciding.
Where this does not apply
FHA loans do not work this way. Mortgage insurance premium on FHA loans terminates on a schedule tied to the loan's terms and original down payment, not on loan-to-value, so neither a recast nor an appraisal removes it early. If you have an FHA loan and want the premium gone, the conversation is about refinancing into a conventional loan, not about ratios.
USDA loans have their own guarantee fee structure with similarly programme-driven rules.
Recent purchases may face a seasoning requirement before a value-based removal request is even considered, commonly two years on many conventional programmes, though some servicers allow earlier requests with documented improvements.
Running it in the right order
If you are doing both, appraise first. The appraisal tells you whether the principal payment is necessary at all, and it is cheaper to find out with an appraisal fee than with a $40,000 transfer.
Then, if the appraisal is enough, request removal and skip the recast entirely. If it is not, apply the principal, then request removal — and ask the servicer to use the appraisal already on file rather than ordering a second one.
