Purchase Price vs Appraised Value for PMI on a Conventional Loan

The Quick Read: On a conventional purchase, the lender measures your loan against the lower of the contract price or the appraised value. That lower number sets your loan-to-value ratio, and the ratio decides whether mortgage insurance applies. A high appraisal does not lower your insurance on a purchase. A low appraisal can raise it.

The Honest Answer: Who Each Value Is Really For

The two values do different jobs, and you do not get to pick one.

The contract price is what you agreed to pay. The appraised value is what a licensed appraiser says the home is worth. On a purchase, the lender uses whichever is lower. If the appraisal comes in at or above the price, the price is the measuring stick, and the extra appraised value changes nothing. If the appraisal comes in below the price, the appraisal becomes the measuring stick, and your leverage goes up.

So the price is the number that matters when the home appraises well. The appraised value is the number that matters when it does not. On a refinance the rule flips: the current appraised value is used, with no price to compare against.

Here is the short version of who each number serves:

• Purchase price: governs your loan when the appraisal meets or beats it. It is the number most buyers plan around.
• Appraised value: governs your loan when it comes in under the price. It protects the lender, and it can cost the buyer cash or a higher insurance requirement.

Side-by-Side

Rows like credit floor and occupancy do not change with this choice. They follow the program. On the wholesale conventional programs I place files with, the decision score starts at 620, and the automated finding governs most files, with a 50% total ratio ceiling. Purchase leverage runs to 97% on a one-unit principal residence when at least one borrower is a first-time buyer, and to 95% otherwise. All of it is subject to lender guidelines and full file review.

How the Lender Actually Does the Math

The formula is simple. Take the loan amount, add any financed mortgage insurance, and divide by the lower of the sales price or the appraised value. Fannie Mae’s Selling Guide on LTV ratios describes the same method, and it adds a rounding step: the result is cut to two decimals, then rounded up to the next whole percent.

That rounding matters. A loan that lands a hair over a threshold is treated as being in the next band. Nobody gets credit for being almost under it.

Seller concessions work the same way. Credits above the allowed limits are treated as sales concessions, and they reduce the sales price used for LTV. The lower of that reduced price or the appraisal is then used.

Walk through the three cases using percentages, not dollars. Say a buyer plans 5% down on a one-unit home, so the planned LTV is 95%.

1. Appraisal above price. The price is still the lower number. LTV stays at 95%. Mortgage insurance applies because the loan is above 80%, the same as planned.

2. Appraisal equal to price. Same result. Nothing moves.

3. Appraisal below price. The appraisal is now the lower number. The same loan amount divided by a smaller value gives an LTV above 95%. That may push the file past the program’s leverage cap, or into a higher insurance tier. The buyer either brings more cash to restore the planned LTV or accepts the higher one, if the program allows it.

When the Contract Price Is the Better Fit

The price governs when the home appraises at or above the contract. That is the usual outcome in a steady market, and it is the clean path.

This is the best case for a first-time buyer using 97% leverage. With only 3% down, there is no room for a value shortfall. A low appraisal would push the file past the cap, and the buyer would need more cash. When the appraisal supports the price, the file stays where it was planned. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.

Some points to know when the price is the working number:

• A high appraisal does not help. If the home appraises well above the price, you do not get a lower LTV or a smaller insurance requirement on a purchase. This is the most common misunderstanding I see.
• Mortgage insurance is required above 80% LTV. It can be cancelled at 80% of original value on request, and the servicer must end it automatically at 78%.
• Your down payment is measured against the price, so the cash you planned holds.

When the Appraised Value Is the Better Fit

“Better” is an odd word here, because the appraised value only governs when it is the lower number. Still, there are cases where it is the value that decides the file.

Refinances. On a refinance, the current appraised value is the value. There is no price to compare. A strong appraisal can lower your LTV and may help you reach a better insurance position. Rate-and-term refinances on a one-unit principal residence go to 95% LTV, and cash-out goes to 80%, again subject to lender guidelines.

New York non-co-op properties. State law there bases mortgage insurance on fair market value, which regulators treat as the appraised value. If the appraisal exceeds the price, insurance may not be required where the standard rule would require it. Co-ops use the purchase price of the ownership interest. Fannie Mae’s guide on mortgage insurance provisions notes the New York exception.

Affordable and shared-equity products. Some programs let the automated system base LTV only on appraised value for a purchase. These apply to principal residences only. If you are in one of these programs, your loan officer will tell you which rule applies.

Low appraisals. When the appraisal falls short, the appraised value governs by default, and you have choices:

• Pay the gap in cash to hold your planned LTV.
• Ask the seller to lower the price.
• Request an appraisal reconsideration with recent comparable sales the appraiser may have missed.
• Walk away if your contract has an appraisal contingency.

Each choice has an insurance consequence. Paying the gap keeps your tier. A price cut resets the price to the new, lower number. Accepting a higher LTV may add or raise insurance, if the program allows that leverage at all.

Why the Number Follows You After Closing

The value used at closing becomes your “original value” for later insurance removal. Under the federal Homeowners Protection Act, the CFPB’s compliance procedures define original value as the lesser of the contract sales price or the appraised value at consummation. On a refinance, it is the appraised value the lender relied on.

That means a low appraisal does double duty. It raises your LTV at closing, and it sets a lower benchmark for removal later.

Here is what the removal rules say, per the CFPB’s consumer guidance on removing PMI:

• You can ask the servicer to cancel when the scheduled balance reaches 80% of original value.
• The servicer must end it automatically at 78% of original value, if you are current.
• A request needs to be in writing, with a good payment history, no junior liens, and evidence that the value has not fallen below original value.
• Final termination happens at the loan’s midpoint if you are current.

One point trips people up. The scheduled dates are based on original value, not today’s value. A new appraisal is only evidence that your value has not declined. It does not reset the date. Cancelling early because the home has gained value is a separate route under the investor’s servicing rules, and it usually needs a fresh valuation at your own expense.

Different rules may apply if the lender pays for the insurance. FHA and VA loans work differently as well, and your servicer can tell you how.

Where Files Go Wrong

These are the failure points I see most often on purchase files:

• Planning cash on the price alone. Buyers budget the down payment from the contract and forget that a low appraisal can change the number.
• Assuming a high appraisal helps. It does not on a purchase. Plan around the price.
• Ignoring the rounding. A file that sits just over a band edge is treated as the next band.
• Counting on 80% to end insurance automatically. At 80% you must ask. Automatic termination comes at 78%.
• Forgetting concessions. Large seller credits can reduce the price used for LTV.
• Skipping the contingency. Without an appraisal contingency, a shortfall falls on you.

Keep your savings paperwork current and your contract dates clear. If the appraisal lands low, a quick conversation with your loan officer about the options is much cheaper than a surprise at closing.

Key Terms Defined

Purchase price: The amount in your signed contract.

Appraised value: The home’s value as estimated by a licensed appraiser using comparable sales.

LTV (loan-to-value): The loan amount, plus any financed mortgage insurance, divided by the lower of price or appraised value.

PMI (private mortgage insurance): Insurance on a conventional loan above 80% LTV that protects the lender. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.

Original value: The lesser of the sales price or the appraised value at closing, used to time PMI removal.

A Balanced Verdict

Neither number wins on its own. On a purchase, the lower of the two governs, so a good appraisal leaves your plan intact and a bad one raises your leverage and your cash needs. On a refinance, the appraisal is the value. Later, the original value fixes your removal dates, which makes the closing-day number matter for years.

If you are buying with a thin down payment, treat the appraisal as the main risk to your cash plan.
