The Quick Read: On a purchase, the lender measures your loan against the lower of the sales price or the appraised value. That ratio, called loan-to-value (LTV), decides whether you owe private mortgage insurance (PMI) and how much coverage the loan carries. Above 80% LTV, PMI is required. A high appraisal does not help you on a purchase. A low appraisal can hurt. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Key Takeaways
- On a purchase, the value is the lower of price or appraisal. On a refinance, it is the appraisal or another accepted valuation method.
- PMI is required on a conventional first mortgage above 80% LTV.
- Three parties touch PMI: the lender picks the value, the insurer prices the coverage, and you control price, down payment, and credit.
- A low appraisal can raise your LTV, add PMI, or push you into a higher coverage tier.
- Removing PMI later is measured on original value, not on what the home is worth today. Every figure here varies by lender and program.
What Does “Setting PMI” Actually Mean?
Nobody sets PMI alone. Three parties each control a piece, and the confusion comes from blending them together.
Conventional payment estimate
The starting figures are an example price at the first-time buyer’s minimum down payment. Replace them with yours.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a conventional loan quote.
Estimate seeded at the low end of Fannie Mae’s published range (0.58%–1.86% a year); the insurer prices the actual premium on the score and the leverage. Applies only above 80% loan-to-value.
Illustrative starting assumptions: a $350,000 price, the first-time buyer’s minimum down payment, a thirty-year term at the current Freddie Mac benchmark, mortgage insurance at the low end of Fannie Mae’s published range, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a conventional loan quote; your rate is set by the lender at lock. The mortgage insurance figure is an editable estimate seeded from Fannie Mae’s published typical range, not a premium quote; the insurer prices the actual premium, and the cancellation month assumes scheduled payments with no extra principal and no change in value. Taxes, insurance and dues are editable estimates; closing costs are not included. Conforming loan limits apply by county. Licensed in sixteen states for consumer mortgages.
| Party | What it controls |
|---|---|
| Lender | Which value goes into the LTV, and the loan amount |
| Mortgage insurer | The premium grid, based on LTV band and credit |
| You | Price, down payment, and credit profile |
PMI is insurance that protects the lender if you stop paying. You pay for it, but it does not protect you. That is why it shows up when your down payment is small. Less of your own money in the deal means more of the lender’s money at risk.
When people say “the lender sets my PMI,” they usually mean the lender picks the value and the loan amount. Those two inputs produce the LTV. The insurer’s pricing grid then takes it from there.
Which Value Does the Lender Use on a Purchase?
The lower of the sales price or the current appraised value. Fannie Mae’s Selling Guide states this rule for purchase loans, and Freddie Mac follows the same logic.
The formula is simple: loan amount divided by that lower value. If you borrow 95% of the price and the appraisal matches, your LTV is 95%.
Here is the part many buyers miss. If the appraisal comes in above the price, the lender still uses the price. You negotiated a deal, and the lower number wins. The appraisal can only hurt you here, never help.
One more wrinkle. If mortgage insurance is financed into the loan, the financed amount is added to the loan before dividing. That nudges the LTV up, so a buyer who finances the insurance can land a notch higher than expected.
What Happens When the Appraisal Differs From the Price?
Take one loan and run it three ways. Assume a purchase with 5% down, which is the standard purchase leverage of 95% LTV on a principal residence. These are modeled assumptions, not market data. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
| Scenario | Value the lender uses | Resulting LTV | What it means |
|---|---|---|---|
| Appraisal above price | The price | 95% | No change. PMI applies. |
| Appraisal equals price | The price | 95% | PMI applies as planned. |
| Appraisal below price | The appraisal | Above 95% | Higher LTV. May exceed the program limit. |
The third row is where files get tense. If the appraisal falls short and your LTV rises past what the program allows, the deal needs a fix. A lower value can also move you into a higher coverage tier or a different pricing band, even when you stay under the program limit.
The bracket effect matters too. PMI starts above 80% LTV. A small value change that pushes you from exactly 80% to just over it adds a premium line to your monthly budget. The same logic applies at other LTV band edges. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Why a Low Appraisal Hurts Twice
A low appraisal does two things at once. It raises your LTV, and it often forces a decision about money.
You have three realistic paths:
- Bring more cash. A larger down payment brings the LTV back down.
- Renegotiate the price. If the seller agrees, the price drops toward the appraised value.
- Accept a higher LTV. This only works if the program allows it, and it can add PMI or raise coverage.
You can also ask for a reconsideration of value if you have better comparable sales than the appraiser used. Results vary, and the appraiser must agree. The appraisal fee itself is a closing cost, whether the number comes in high or low.
Some loans qualify for an appraisal waiver or value acceptance instead of a full appraisal. That changes who carries the risk of a wrong valuation. It does not change the LTV math. Fannie Mae also offers relief from certain representations and warranties when an appraisal on an eligible one-unit property scores 2.5 or below in its collateral underwriter tool. The lender gets protection. The PMI logic stays the same.
How a Refinance Differs
A refinance has no sales price. So the appraised value sets the LTV, or another acceptable valuation method does, such as an automated valuation model.
| Factor | Purchase | Refinance |
|---|---|---|
| Value used | Lower of price or appraisal | Appraisal or accepted alternative |
| Can a high value help? | No | Yes |
| PMI trigger | Above 80% LTV | Above 80% LTV |
This is the one place where a high appraisal helps. On a refinance, a higher value lowers your LTV, and that can bring you under the 80% line.
For a rate-and-term refinance on a one-unit principal residence, the wholesale programs we use reach 95% LTV, with mortgage insurance above 80%. For a cash-out refinance, the cap is 80% on a one-unit principal residence, subject to lender guidelines. Those caps differ from purchase leverage, so do not assume one number fits all.
From LTV to Premium
Once the LTV is set, the insurer’s grid takes over. Two inputs drive it: your LTV band and your credit score. Higher LTV and lower credit mean a higher premium.
Published typical annual premiums run from 0.58% to 1.86% of the loan balance. That is a range, not a quote. Your actual figure depends on your file, and your Loan Estimate shows it.
The same ratio also drives coverage depth. Fannie Mae’s rules on coverage set how much of the loan the insurance must cover by LTV and transaction type. Some loans can carry less than standard coverage, but the lender takes a pricing adjustment for that choice.
Credit is one input you can work on before applying, alongside price and down payment. The wholesale conventional programs start at a 620 decision score. A stronger score can improve where you land in the grid, subject to lender guidelines and full file review.
To see how these programs fit your file, look at Lendmire’s conventional loan programs page for what each one asks of the borrower.
Special Valuation Situations
The general rule has exceptions. Here are the named ones that matter.
Affordable LTV (appraised value only). For shared-equity transactions and Community Seconds with a subsidized sales price, Fannie Mae’s underwriting system calculates LTV on the appraised value alone, not the lower of the two. These options apply only to principal residences.
HFA Preferred. For borrowers at or below 80% of area median income, this program carries reduced mortgage insurance coverage. Above that income level, standard coverage applies. The first-time-buyer path reaches 97% LTV on a one-unit principal residence with a fixed rate, subject to lender guidelines.
Financed mortgage insurance. The financed amount is added to the loan before the LTV is calculated, as noted above.
Occupancy. Leverage depends on how you use the home. A principal residence gets the highest leverage. A second home reaches 90%. Occupancy, not the value rule, decides the cap.
Lender-paid insurance. Some loans build the cost into the pricing instead of billing you monthly. These generally do not cancel the way borrower-paid PMI does. Ask how any structure works before you choose it.
Value and Cancellation: Which Number Counts Later
Here is where people get tripped up. The value used to set PMI at purchase is not the value used to remove it.
Under federal rules, the CFPB explains that your servicer must end PMI automatically when your balance is scheduled to reach 78% of the home’s original value, if you are current on payments. You can ask for cancellation earlier, at 80%, and the servicer may want proof that the value has not dropped.
Original value generally means the lower of the price or appraisal at purchase. Home price growth does not change that number for these federal rules.
The wholesale programs we place files with follow the same pattern. Cancellation at 80% of original value needs good payment history, no subordinate liens, and no decline in value.
A separate path exists if your home has gained value. Under Freddie Mac’s servicing rules, a servicer may cancel based on current value. That requires an LTV of 75% or less after two to five years of seasoning, or 80% or less after more than five years. Substantial improvements can waive the two-year wait. This is a request-based investor process, often needing a new valuation. It is not automatic.
Keep your payment history clean. A late payment can delay cancellation.
Common Misconceptions
“A higher appraisal lowers my PMI.” On a purchase, the price caps the value used.
“PMI is based on today’s home value.” Automatic termination uses original value. Current-value cancellation is a separate process with seasoning and valuation requirements.
“PMI lasts forever.” Borrower-paid PMI has set cancellation and termination points. FHA mortgage insurance works differently, so do not mix them up.
“Cancellation is automatic at 80%.” It is not. That step is a request, and only the 78% point ends PMI without one.
What Your Decision Looks Like in Practice
Most of the leverage you have comes before the appraisal, not after.
1. Pick your down payment with the 80% line in mind. The difference between 80% and a hair above it is a whole premium line.
2. Check your credit early. It moves your place in the insurer’s grid.
3. Plan for the low-appraisal case. Know how much extra cash you could bring, or whether you would renegotiate.
4. Ask how PMI is paid. Monthly, upfront, or a blend each have different mechanics.
5. Track your balance. Know when you hit 80% of original value so you can request cancellation.

Frequently Asked Questions
Does a high appraisal reduce my PMI on a purchase?
No. The lender uses the lower of the price or the appraisal, so an appraisal above the price changes nothing. The price stays the value. The appraisal only matters when it comes in lower.
What happens if my appraisal comes in below the price?
The lower value sets your LTV, which can add PMI or raise your coverage tier. You can bring more cash, renegotiate the price, or ask for a reconsideration of value. Your options depend on the program and the lender’s guidelines.
Who actually sets the PMI premium?
The mortgage insurer prices it using a grid built on LTV band and credit. The lender chooses the value inputs and arranges the coverage. You influence the result through your price, down payment, and credit.
Can I remove PMI if my home has gained value?
Possibly, but it is a different process. Federal automatic termination is based on original value. Some servicers will cancel on current value after seasoning and a new valuation, subject to the investor’s rules and a clean payment history.
Is PMI the same as FHA mortgage insurance?
No. They work under different rules, and FHA insurance has its own premium structure and removal terms. Do not assume what applies to conventional PMI applies to an FHA loan.
