How to Buy Now on a Conventional Loan With PMI Instead of Waiting

The Quick Read: Buying with less than 20% down is a normal, well-worn path, and private mortgage insurance (PMI) is the tool that makes it work. On a primary residence, the wholesale programs Lendmire places files with go to 97% of the price with a fixed rate when at least one borrower is a first-time buyer, and 95% otherwise. PMI adds a recurring cost, but it is not permanent: it can be cancelled at 80% of the original value and must end at 78%. Whether buying now beats waiting depends on your cash reserves, your income stability, and how long you plan to stay, not on the 20% number alone.

Twenty percent is the point where PMI stops being required. It is not the minimum to buy. That distinction drives everything below.

What PMI Is and Who It Protects

PMI is insurance on a conventional loan that pays the lender if the borrower defaults. It protects the lender, not you. If you fall behind, you can still lose the home. What it does for you is open the door: a buyer who would otherwise need years of saving can qualify now.

PMI is not homeowners insurance. Homeowners insurance covers damage to the house. PMI covers the lender’s loan risk. You pay both, and they do different jobs.

The rule behind it is simple. The Fannie Mae Selling Guide requires mortgage insurance, or another approved credit enhancement, on a conventional first mortgage above 80% loan-to-value (LTV). Below that line, no PMI.

How Much Down Do You Actually Need?

The answer depends on who is buying and what they are buying. Across the wholesale conventional programs, these are the purchase limits:

Those figures match the agency ceilings in the Fannie Mae Eligibility Matrix, which shows 97% for a one-unit fixed-rate purchase and 95% for an adjustable rate. For the 97% lane, Fannie Mae’s 97% LTV FAQ adds that the loan must be fixed-rate, on a one-unit principal residence, and run through automated underwriting. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

“First-time buyer” has a specific meaning here: no ownership interest in a residence in the previous three years. Someone who sold a home four years ago can qualify.

Two more programs, HomeReady and Home Possible, work differently. They carry an income limit of 80% of area median income, so they suit lower- and moderate-income buyers who may not be first-timers. A buyer over that income cap who is a first-time buyer can still use the standard 3% option. A repeat buyer over the cap generally lands in the 95% lane instead.

Occupancy decides leverage, and the maximums drop as the home moves away from your primary residence. For the full menu, see Lendmire’s conventional loan programs.

How the Loan Is Underwritten, Step by Step

Here is how a low-down-payment conventional file moves from application to closing.

1. Product match. The loan officer sorts you by profile: first-time buyer status, income relative to area median, property type, and fixed versus adjustable rate.

2. Automated underwriting. The automated system weighs credit, income, assets, debts and LTV together. Loans above 95% LTV must run through it. Strong factors elsewhere in the file can offset a thin one.

3. Credit and ratios. The wholesale conventional programs start at a 620 decision score, or 640 on an adjustable rate under manual underwriting. The automated finding governs most files, with a total debt ratio ceiling of 50%. Manually underwritten loans run 36% or 45%, depending on score and reserves.

4. PMI structure. Coverage is set by LTV band. Higher LTV means more insurer coverage and a higher premium. The premium itself depends on your credit, down payment and loan terms.

5. Appraisal. This step decides the real LTV. LTV is based on the lower of the price or the appraised value. A low appraisal pushes LTV up, which can raise insurance cost, break the program maximum, or require more cash at closing.

6. Conditions and closing. Documents follow the automated findings: income, assets, ID, and gift letters where relevant.

On cost, published typical annual PMI premiums run 0.58% to 1.86% of the loan balance. That is a range, not a quote. Your actual figure appears on page 1 of your Loan Estimate under projected payments. Some loans use a one-time upfront premium instead, which shows in the closing-cost section.

Where the cash comes from

For a one-unit purchase, the standard 97% product does not require the borrower’s own savings for the down payment. Gifts, grants and community second liens can be eligible sources. Homebuyer education may be required when every borrower is a first-time buyer. You still need funds for closing costs and reserves, which is where many “buy now” plans actually break.

PMI Is Not Forever

The most common misunderstanding is that PMI lasts for the life of the loan. That describes FHA mortgage insurance, a different product. Conventional PMI has an exit built into federal law. Under the Homeowners Protection Act, on a primary residence:

• You can request cancellation at 80%. When the balance is scheduled to reach, or actually reaches, 80% of the original value, you may ask in writing. You need a good payment history and no subordinate liens, and the servicer may require proof the value has not declined.
• The servicer must terminate it at 78%. At 78% of the original value on the original amortization schedule, termination is automatic if you are current.
• A backstop exists. PMI must end the month after the midpoint of the loan term if you are current.

The CFPB’s guidance on removing PMI lays out these steps. Two traps matter in practice.

First, the statutory dates use the original value. If your home appreciates, you may be able to request removal earlier based on current value, but that is a servicer policy and usually needs an appraisal and a clean payment history. Ask your servicer what it requires.

Second, lender-paid PMI is different. It is built into the loan terms and generally cannot be cancelled by the borrower. It usually costs more over time through a higher interest charge. Ask which structure you are being offered.

What Waiting Actually Costs

Waiting looks free. It is not. While you save toward 20%, several things keep moving:

• Rent continues and builds no equity.
• Prices can rise while you save, pushing the 20% target higher.
• Borrowing costs can shift in either direction, and no one can predict which.
• Cash gets tied up. Putting every dollar into a larger down payment can leave you thin after closing.

Buying now carries its own costs: a larger loan, a monthly insurance charge, and less cushion against a falling market if you must sell soon. Neither path is free. The right comparison puts both costs on one ledger over the time you expect to stay.

A Five-Question Buy-or-Wait Test

Run your own file through these checks. Each one leans one direction.

Most files lean one way on three or four of these. If the answers split, the reserve question usually carries the most weight. PMI is rarely the real reason to wait. Thin reserves are.

Short wait versus long wait

A wait of a few months for a specific, reachable goal is a different decision from an open-ended wait for 20%. Raising a credit score into a better pricing band, paying off a card to improve your debt ratio, or finishing a probationary period at work can each justify a short, defined pause. “Until I have 20%” can stretch for years while rent and prices keep moving. Set a date and a target. If you cannot name either, the wait is probably the more expensive choice.

Where the General Rule Breaks

The “97% and cancel at 80%” story has exceptions worth knowing.

• Adjustable-rate loans top out at 95% on the agency matrix, not 97%.
• Multi-unit homes cap at 95%, and a standard manufactured home is generally limited to 95% as well.
• Loan size matters. The loan must fit within the county’s conforming limit, and high-balance loans are not eligible for the 97% option. Limits vary by county and unit count, so confirm yours with your loan officer.
• Credit events create waiting periods. The agencies set four years from a chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed-in-lieu, shorter with documented extenuating circumstances. Those are agency rules, not lender preferences.
• A low appraisal can undo the plan by raising LTV past a program or insurance threshold.
• Falling values can complicate early PMI removal, since servicers may require proof the value has held.

Ways to Avoid or Reduce PMI

A wholesale lane also exists on cash-out refinances that reaches 89.99% LTV with no mortgage insurance at a 680 score, but that applies to refinancing an existing home, not buying one. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Key Terms Defined

PMI (private mortgage insurance): Insurance on a conventional loan that protects the lender if you default, required above 80% LTV. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

LTV (loan-to-value): The loan amount divided by the lower of the price or appraised value.

First-time buyer: A borrower with no ownership interest in a residence in the previous three years.

AMI (area median income): The local income benchmark that HomeReady and Home Possible use for their 80% income limit.

Automated underwriting: The system that weighs credit, income, assets and LTV to produce a finding on the loan.

Original value: The lower of the price or appraisal at purchase, which sets the statutory PMI cancellation dates.
