Is PMI Based on Appraised Value?
PMI is usually based on the lower of appraised value or purchase price, not home insurance, which covers rebuilding cost instead.

What Sets PMI
PMI is calculated by your lender off the loan amount compared to appraised value or purchase price, whichever is lower. It has nothing to do with the homeowners policy you're shopping for now. The two numbers are handled by different parties for different reasons.
What Your Policy Covers
Your home insurance dwelling coverage is based on what it would cost to rebuild the house, not what it sold for or what it appraised at. A house can appraise for less than rebuilding costs, especially with older construction or higher material prices in your area.
What The Lender Wants
Before closing, the lender wants proof of a binder showing dwelling coverage at least equal to the loan amount, sometimes more. That figure comes from a rebuilding cost estimate, not the appraisal. Check your binder against what the lender actually asked for in writing.
Where Escrow Fits In
If your loan has escrow, both PMI and your home insurance premium get folded into the same monthly mortgage payment. They're collected together but calculated separately. Your declarations page will show the insurance premium amount that escrow is covering.
Get the Dwelling Number Right Before You Bind
Dwelling coverage is set by rebuilding cost, not appraisal or loan amount. Comparing quotes now means checking that figure matches what your house would actually cost to rebuild, not just what satisfies the lender.
When Does PMI Go Away
PMI isn't permanent. Once enough of the loan is paid down, a conventional loan's PMI can be canceled, either because the homeowner requests it or because the lender is required to drop it automatically. The exact equity threshold and timing are set by federal rules for most conventional loans, though the fine print depends on the loan type and the servicer handling it.
The value used for this calculation is the original appraised value or purchase price from closing, the same number PMI was based on at the start. It doesn't update with the local market, and it has nothing to do with any rebuilding cost estimate used for insurance. If a home's value has risen faster than expected, some lenders allow a new appraisal to prove the equity threshold has been crossed sooner. That option usually comes at the homeowner's own cost and isn't guaranteed.
Dwelling coverage runs on a separate track. It doesn't shrink as the loan balance goes down, because it was never tied to the loan in the first place. It stays tied to rebuilding cost, which tends to rise over time with labor and material prices rather than fall. PMI is working toward an exit. The insurance side of the mortgage payment often moves the other direction at renewal.
FHA loans work differently. Most require mortgage insurance premiums for the life of the loan, regardless of equity, unless the loan is refinanced into a conventional one. For someone in that situation, canceling PMI the way a conventional borrower would isn't on the table. Checking the loan documents or asking the lender directly is the only way to know which rules apply, since the loan type decided at closing sets the terms for everything that follows.
Does Dwelling Coverage Change When PMI Drops Off
No. When PMI ends, nothing about the homeowners policy changes because the two were never linked. PMI protects the lender against the loan balance. Dwelling coverage protects against the cost of rebuilding the house. One can disappear from the mortgage payment entirely and the other keeps running at whatever premium the insurer sets, renewal after renewal.
It's worth saying plainly because the escrow statement can make it look otherwise. For years, PMI and the insurance premium sit on the same line of the monthly payment, collected by the same servicer. When PMI drops off, the payment goes down, and it's easy to assume the insurance piece shrank along with it. It didn't. The servicer just stopped collecting for one of the two things it used to collect for.
Dwelling coverage doesn't need to be revisited just because PMI milestones are being hit. What does call for a second look is the rebuilding cost estimate itself, especially a few years in. Material costs and local labor rates move over time, almost always upward, and a dwelling limit set at closing can fall behind what rebuilding actually costs by the time a claim happens. That's a question for the insurance policy on its own terms, not something tied to how much equity has built up or when PMI is scheduled to end.
Anyone tracking PMI removal as a milestone can treat the insurance side as a separate task on a separate calendar. The declarations page shows the current dwelling limit and when the policy renews. That's the number worth checking against rebuilding costs from time to time, independent of anything happening with the loan balance or the lender's PMI rules.
One Number to Check Now
Compare the dwelling limit on your binder against a current rebuilding cost estimate for your house, not the purchase price or appraisal. That's the figure the lender needs and the one that protects you later.
