How Much More Down Lowers PMI on a Conventional Loan for a Condo

The Quick Read: More down lowers PMI in steps, not in one jump. Each lower loan-to-value band cuts the coverage the insurer must carry, and reaching 80% LTV removes the requirement. Credit score and the insurer’s own pricing also move the cost, so the size of the saving depends on the file. A bigger down payment will not rescue a condo project that fails review. The building has to pass on its own. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.

How Does PMI Work on a Condo?

PMI is tied to one line: 80% of the property’s value. On a conventional loan, the part of the balance above that line needs mortgage insurance. Fannie Mae’s rules work the same way.

LTV is the loan amount divided by value. Value is generally the lower of the purchase price and the appraised value. That detail matters on a condo. If the appraisal comes in low, LTV goes up after you have already committed to the price. Your down payment as a percentage of price no longer matches your down payment as a percentage of value.

For a principal residence, the wholesale conventional programs allow up to 97% LTV, a 3% down payment, when at least one borrower is a first-time buyer and the rate is fixed. Otherwise the standard purchase leverage is 95%, which means 5% down. Those programs are the outer edge of the PMI bands. Lendmire arranges these loans through wholesale lenders as a mortgage broker. The conventional loan programs all follow the same 80% line. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Condos qualify on the same terms as a house at these leverage levels, as long as the project is eligible. The agency’s 97% LTV options include eligible condos. They are fixed-rate and run through automated underwriting. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Why Does More Down Lower PMI Before You Reach 80%?

Because the insurer’s required coverage drops as the loan shrinks relative to value. Fannie Mae’s Selling Guide on mortgage insurance coverage groups loans into LTV bands above 80%. The bands step down in five-point increments toward the top of the range. Required coverage is highest in the top band and lower in each band below it. Shorter fixed-rate terms carry lower coverage in the first bands than longer terms and adjustable rates.

Think about what coverage means. If a loan at 95% LTV defaults and the property sells for less than the balance, the insurer takes on a bigger piece of the loss. At 85% LTV, the lender is already protected by a larger equity cushion, so less coverage is needed. Less coverage means less risk for the insurer, and that shows up in the premium. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Here is the catch. The coverage percentage is not your PMI rate. It tells you how much of the balance the insurer is on the hook for. The private insurer then prices the policy off that exposure, your credit score, the term and other file features. No agency publishes a premium schedule, so no article can tell you the exact saving. The Loan Estimate does.

The Down Payment Ladder on a Condo

This table shows direction, not price. A buyer at 10% down on a condo usually pays less in monthly mortgage insurance than a buyer at 5% down on the same unit. A buyer at 15% usually pays less again. The 20% rung removes the line entirely.

A second effect often gets missed. A larger down payment also shortens how long PMI lasts, because a buyer who starts closer to 80% LTV has less ground to cover before reaching it. So more down cuts both the monthly cost and the number of months you pay it.

Does a Condo Change the PMI Math?

Not directly. The coverage bands are the same for a condo and a house. What changes is everything around the insurance.

Pricing add-ons. Fannie Mae’s loan-level price adjustments are a matrix of added costs based on credit score, LTV, occupancy, property type and other features. The matrix includes a condo line item, so condos can carry an added pricing adjustment at higher LTVs. Those adjustments usually show up in the rate or as points. The matrix text is dense and changes, so the Loan Estimate is the place to see what applies to your file. More down can reduce that adjustment too.

HOA dues in the ratios. Dues count in your monthly obligations. On a condo, PMI and HOA dues both sit in the debt-to-income ratio at the same time. The wholesale conventional programs allow a total ratio up to 50% on a file that gets an automated approval. A larger down payment lowers PMI and the loan payment. That gives you more room under the ratio when dues are high.

A project review. The building gets reviewed along with you. The project review sits on top of your borrower underwriting, the transaction terms and the appraisal of your unit. Typical items include the condo questionnaire, the HOA budget, the master insurance policy and any litigation disclosure.

Occupancy. Leverage depends on how you use the unit. A principal residence goes to 95% (97% for qualifying first-time buyers). A second home tops out at 90%. Investment property is on a different footing and outside the scope of this article.

Where the “Bigger Down Payment, Easier Condo” Rule Breaks

A bigger down payment used to lighten the project review. A condo bought as a primary residence at a lower LTV could often qualify for a limited review of the building. That shortcut has changed.

Fannie Mae’s project standards FAQ says the Limited Review has been retired for applications taken on or after an early-August cutoff. There is a carve-out for certain Florida LTV rules on earlier applications. Established attached-unit projects now go through a full review, an FHA project approval route or a streamlined review option. Some project types are waived, including detached condo units and certain small projects.

What does this mean for a buyer? Putting more down still lowers PMI. It no longer buys a lighter look at the building. A low-reserve HOA, heavy litigation or a poorly insured master policy can sink a file at any down payment. The project has to pass on its own. Check the project’s status early, before you spend money on an appraisal.

Ask your loan officer to confirm which review applies to the building before you commit to a price. That one question can save a contract.

Is the Extra Down Payment Worth It?

It depends on what the cash would do otherwise. The decision is not “20% or nothing.” Each extra step has a cost (cash tied up) and a return (lower PMI and a shorter PMI period).

Consider a buyer with a condo price in mind and two options. Option one puts 5% down and keeps a larger cash cushion. Option two puts 10% down, drops one band and pays noticeably less PMI each month. The second buyer has less cash after closing. The first buyer pays more every month for insurance that ends later. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

Run the comparison with three questions:

1. How many months of reserves are left after closing? Condo ownership brings special assessments and HOA increases. A buyer who drains savings to trim PMI may be exposed.

2. How long will you stay in the unit? A short stay favors keeping cash. A long stay favors the saving, because PMI savings compound over more months.

3. How much ratio room does the file have? If HOA dues plus PMI push the file near the ratio ceiling, a bigger down payment may be what makes it work.

Gift funds can count toward the down payment under many conventional programs, subject to lender guidelines and documentation. A lower loan balance also helps the ratios.

The honest read: one more band down is often worth it if reserves stay healthy. Stretching to 20% by emptying the account is rarely worth it, because PMI can be removed later.

How Do Credit Score and Down Payment Work Together?

They are the two largest levers on the premium. A higher score at the same down payment usually lowers PMI. A larger down payment at the same score usually lowers it too. The wholesale conventional programs start at a 620 decision score, and PMI pricing is lighter for stronger scores.

Neither lever works alone. A buyer on the edge of a band may find that a modest score improvement does as much as extra cash. Lendmire’s piece How Much a Small Down Payment Conventional Loan Costs on a Condo covers the options that stop short of 20%.

How and When Does PMI End?

PMI is not permanent. Under federal rules, the CFPB explains that you can ask the servicer to cancel it when the balance is scheduled to reach 80% of the home’s original value. You can ask earlier if extra payments get you there. The request has to be in writing, with a good payment history and no junior liens. The servicer may ask for evidence, such as an appraisal, that the value has not fallen below the original value.

Automatic termination comes at 78% of original value if you are current. A midpoint backstop applies at the middle of the loan term. These rules cover principal-residence, single-family loans closed after the law took effect. Some servicers allow removal under their own standards, such as a new appraisal showing higher value.

Two common mistakes:

• Cancellation is not automatic at 80%. You have to ask. Automatic termination is at 78%.
• The standard rules use original value. Current value matters only where your servicer’s own policy allows it.

PMI is also a conventional-loan product. FHA loans have their own mortgage insurance premium, which works differently and often lasts longer.

Key Terms Defined

PMI (private mortgage insurance): Insurance on a conventional loan that protects the lender, required when LTV is above 80%.

LTV (loan-to-value): The loan amount divided by the property’s value.

Coverage: The share of the loan balance the insurer pays if there is a loss. It is not your premium.

LLPA (loan-level price adjustment): A risk-based pricing add-on set by credit score, LTV, occupancy and property type.

Project review: The lender’s check of the condo building’s finances, insurance, litigation and ownership mix.

Condo questionnaire: The form the HOA or management company completes about the project, which the lender uses in the project review.

What the Lender Looks For on a Condo File

A clean condo file has the same borrower items as any conventional purchase, plus the building. Expect to provide the income, asset and credit documents. The credit side starts at a 620 decision score on the wholesale programs, with a total ratio up to 50% on most automated approvals. Manually underwritten loans use tighter ratios.

The building side is what trips files up:

• A completed condo questionnaire, with no blank sections
• The current HOA budget
• Master insurance evidence
• Litigation disclosure
• An appraisal of the unit that supports the price

Complete documents do not guarantee approval, but they leave fewer gaps for the lender to chase. Everything here is subject to lender guidelines and full file review.
