Buying Now With PMI vs Waiting for a Fifth Down on a Conventional Loan

The Quick Read: Buying now with PMI usually fits a buyer who has steady income, a healthy cash cushion after closing, and no near-term reason to expect a big price drop. Waiting fits a buyer who is close to 20% down or expects to move soon. Neither path wins every time. PMI is private mortgage insurance, and it is a temporary cost on a conventional loan, not a permanent one.

“A fifth down” just means 20% of the purchase price. That is the line where PMI stops being required on a conventional loan. The rest of this article refers to buying now as Option A and waiting as Option B.

The Honest Answer: Who Each Option Is Really For

Option A is for the buyer whose finances are stable and who is ready to own. The 20% line is a mortgage insurance threshold, not a rule that you must have 20% down to qualify. Across the wholesale programs Lendmire places files with, conventional purchases reach 97% LTV (3% down) on a one-unit primary residence with a fixed rate, when at least one borrower is a first-time buyer. Otherwise the standard limit is 95% LTV (5% down). LTV, or loan-to-value, is the loan amount divided by the home’s value. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.

Option B is for the buyer who is nearly at 20% and can get there without draining savings. It also suits someone whose job, income, or plans are unsettled. Waiting costs you time, and it exposes you to price changes. It also avoids a monthly insurance charge. That trade is real in both directions.

Many buyers land in a third spot: put down more than the minimum, but less than 20%. That middle path often gets overlooked, and it deserves a place in the comparison.

Side-by-Side

Credit and documentation standards do not change when you put 20% down. What changes is how much of the home you finance, and whether insurance comes with it. Figures are subject to lender guidelines and full file review, and nothing here is a commitment to lend.

The ratio ceiling works the same way on both paths. The automated underwriting finding governs most files, with a total debt-to-income ceiling of 50%. Manually underwritten loans run tighter, at 36% or 45%, depending on score and reserves.

What PMI Actually Is (and Isn’t)

PMI protects the lender, not you. If you stop paying and the home sells for less than you owe, the insurer covers part of the lender’s loss. That is the whole job of the policy.

The federal consumer-finance regulator says borrowers who put down less than 20% typically need mortgage insurance. It says PMI makes the loan more expensive, but it can let you qualify for a loan you otherwise couldn’t get. Most PMI is paid monthly, folded into the payment. Some of the cost can show up at closing instead.

It is not homeowners insurance. Homeowners insurance covers damage to the house. PMI covers the lender’s risk of loss on the loan.

What does PMI cost? Cost depends on your down payment and credit profile. Published typical annual premiums run from 0.58% to 1.86% of the loan balance. That is a range, not a quote. Your real number comes from the insurer after a full file review, and it shows up on your Loan Estimate.

When Buying Now With PMI Is the Better Fit

Buying now tends to be the better fit when these things are true:

• Your savings target keeps moving. If you are saving from a modest base, the 20% goal can drift away as prices change. Reaching it may take years.
• You would drain your reserves to reach 20%. A bigger down payment with an empty emergency fund is a risky trade. Paying PMI while keeping a cushion can be the safer structure.
• You are paying rent that builds nothing. Each month renting is a month with no equity. Each month owning pays down principal, even while PMI is on the loan.
• You plan to stay put. A longer stay gives PMI time to end and gives equity time to build.
• Your credit is strong. Insurance cost depends on credit profile. A solid score can keep the insurance piece more manageable.

Picture a buyer with 5% saved, stable income, and a lease about to end. A conventional loan at 95% LTV may let that buyer purchase now and keep cash for repairs and moving. Waiting another few years to reach 20% might mean buying later, at a different price, in a different market. Nobody can promise which way that cuts. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Here is the part that gets missed. PMI does not last forever on a conventional loan. Under the Homeowners Protection Act, you can request cancellation when your balance is scheduled to reach 80% of the home’s original value. You need a good payment history and no junior liens, and the value cannot have dropped below the original. The servicer must end it automatically at 78%. The CFPB’s PMI removal page lays out those steps.

Extra principal payments can speed up that date. Home appreciation may also help, where the servicer allows cancellation based on a new appraisal. The servicer may require that appraisal, and you may pay for it.

When Waiting for a Fifth Down Is the Better Fit

Waiting is the better fit in these cases:

• You are close. If 20% is within reach in a short stretch, waiting may avoid insurance entirely. A short wait can make sense where a long one does not.
• Your income or job is unsettled. A new mortgage is a long commitment. If your next year is uncertain, time can be worth more than speed.
• You expect to move soon. A short stay gives equity little time to build, and PMI would run for most of it.
• Your credit score is on the low side. Insurance cost tends to rise as credit weakens. Waiting while you improve your score can change the cost of buying.
• You have a credit event to clear. The agencies set waiting periods after events like bankruptcy and foreclosure. A chapter 7 discharge carries a four-year wait. A foreclosure carries seven. A short sale or deed-in-lieu carries four. Shorter periods may apply with documented extenuating circumstances. These are agency rules, and they apply on either path.

Waiting is not free, though. Rent keeps going out. Home prices can rise or fall while you save. Your target may move with them. Savings can also stall, since life has a way of spending them.

One more point favors waiting. A smaller loan means a smaller balance. At 80% LTV or lower, the lender does not require mortgage insurance on a conventional loan. Fannie Mae’s Selling Guide requires it above 80% LTV. On a purchase, the lender uses the lower of the sales price or appraised value to measure that. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

If the appraisal comes in under the price, your LTV rises. A buyer planning on exactly 20% down can land above 80% and owe insurance after all.

A Simple Way to Find Your Own Break-Even

You do not need a spreadsheet to think this through. Work through four questions:

1. How long until you reach 20%? Be honest about your saving pace, not your best month.

2. What will you pay in rent over that time? That is the cost of waiting.

3. What would PMI add to your monthly cost until it ends? Ask for a Loan Estimate on a few scenarios. That is the cost of buying now.

4. What would you have left in savings after closing? Compare reserves under each path.

If waiting takes years and your cushion would be thin either way, buying now often looks stronger. If you are months away from a larger down payment and your cushion is healthy, waiting often looks cleaner. In between, it is a toss-up, and it depends on how you value risk. Some buyers sleep better with no insurance. Others sleep better with cash in the bank.

Test the weak spots, too. What if prices stay flat? What if they rise? What if your savings pace slows? A decision that only works in the best case is a fragile one.

Ways to Soften PMI Without Waiting

You have options besides paying standard monthly PMI or waiting. These are structures to ask about, not promises:

• Financed mortgage insurance. Some programs let the premium be added to the loan. This has limits, and it does not apply to every loan type.
• Lender-paid mortgage insurance. The lender covers the cost in exchange for different loan terms. It is a different structure with different tradeoffs, so compare the full terms.
• A larger down payment than the minimum. Putting down 10% instead of 3% changes the insurance picture without requiring the full fifth.
• Income-based programs. HomeReady and Home Possible carry an income limit of 80% of area median income. They suit buyers under that line who need low-down-payment flexibility. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.

Ask a broker to show you these side by side on a Loan Estimate. Compare the full terms, not just the monthly figure.

Common Mistakes on Both Sides

• Treating 20% as a requirement. It is a mortgage insurance line, not a qualifying rule.
• Forgetting that PMI ends. The 80% and 78% dates are built into the loan.
• Ignoring rent. Waiting has a monthly cost too.
• Draining reserves to hit 20%. An empty account after closing is its own risk.
• Assuming the appraisal will match the price. A low appraisal can change your insurance requirement.
• Assuming cancellation uses today’s value. The automatic and request rights are tied to original value. Cancellation on current value is a separate servicer process with its own conditions.

The Balanced Verdict

Buy now with PMI if you are stable, ready, and would otherwise spend years chasing a moving target. Wait if you are close to 20%, uncertain about your next year, or likely to move soon. If you sit between those, the middle path of putting down more than the minimum may fit best.

The right answer depends on your file: your credit, your reserves, your income, and your timeline. Running both scenarios before deciding shows how each path fits your file.
