Should a Move-Up Buyer Put Sale Equity Down to Keep a Conventional Loan?

The Quick Read: It depends on how close your loan lands to the conforming limit and how much cash you keep afterward. No Fannie Mae or Freddie Mac rule forces you to put sale proceeds down. Using them can shrink the loan, cut or end mortgage insurance, and keep a borderline file conventional. But emptying the account leaves you with no cushion.

Here is the short rule. Put in enough equity to reach a meaningful line: 80% loan-to-value (LTV, the loan as a percentage of the home’s value) or the conforming limit. Past that line, each extra dollar buys less than the cash it drains. Below it, a bigger down payment often earns its keep.

The sections below walk through the mechanics, the exceptions, and how to decide. Lendmire is a mortgage broker, and the program figures here reflect what its team sees across the conventional loan programs it arranges through wholesale lenders. Every figure is subject to lender guidelines and full file review. Nothing here is a commitment to lend.

Can Sale Proceeds Fund Your Down Payment?

Yes. Proceeds from the sale of your current home are an eligible source for both the down payment and closing costs. Where the sale has not closed yet, the lender can sometimes qualify you on anticipated proceeds, but it must still document the cash you actually receive.

Fannie Mae’s Selling Guide on anticipated sales proceeds lays out the sequence. The lender needs the old home’s settlement statement at or before the new closing. That statement must show enough net cash to close the purchase. If the old sale slips, the new loan can stall.

Equity is not cash. Equity is what the home is worth minus what you owe. Net proceeds are what remains after the agent’s commission, closing costs, repairs you agree to, and every lien. Plan on the net number. It is always smaller than the one you carry in your head.

What Is Your Equity Really Worth?

Your usable equity is the sale price minus sales costs and all liens. If your home is listed but has no contract, the lender does not take your list price at face value. Fannie Mae’s guide uses 90% of the listing price minus liens, and notes that the 10% haircut can be adjusted for market conditions.

That haircut is a reminder: anticipated proceeds are an estimate, not money in hand. A buyer who sizes the down payment to the last dollar of projected equity is betting that the sale price, repair credits, and timing all land perfectly. Build a cushion into the number. Treat the final settlement statement as the only figure that counts.

Money from a 1031 exchange is accepted if it is properly documented and compliant with the tax code. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.

Why Loan Amount, Not Price, Decides Your Loan Type

Your loan amount determines the category. A conforming loan stays at or under the county limit set by the Federal Housing Finance Agency. Anything above the applicable limit is jumbo, which falls outside the Fannie and Freddie framework. Limits vary by county and unit count, so look yours up on the FHFA conforming loan limit page.

That makes the down payment a lever. Picture a buyer eyeing a home priced a little above what the county limit supports at 95% LTV. Putting down 10% instead of 5% shrinks the loan. If the smaller loan slips under the limit, the file stays conventional. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

Jumbo lenders set their own rules. Across the wholesale jumbo lanes Lendmire works with, the decision score starts at 660, leverage reaches 90%, and loans run up to $5,000,000, with a 50% ratio ceiling on the fixed lanes. Those are broader guidelines than the conforming envelope, and they differ from lender to lender, so ask for a written policy before you assume anything.

Jumbo is not a failure. The question is whether crossing the line costs you more than the equity you would commit to stay under it.

How Down Payment Size Changes Your Mortgage Insurance

Mortgage insurance is required above 80% LTV on a conventional loan. Fannie Mae’s private mortgage insurance page says it is usually required when the down payment is under 20%, and that it “is not forever.”

The mechanics are simple. Put down 20% or more and there is no insurance. Put down less and you pay it as a share of the balance. Published typical annual premiums run from 0.58% to 1.86% of the balance. That is a range, not a quote. Your credit score and LTV move you within it. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

Conventional insurance also ends. You can request cancellation when the balance is scheduled to reach 80% of the home’s original value, if you have a good payment history, no subordinate liens, and no decline in value. The servicer must terminate it automatically at 78% if you are current. The CFPB’s guidance on removing PMI lays out the conditions. The rule applies to single-family principal residences.

So the real question on insurance is not “avoid it forever.” It is “how long will I carry it, and what does that cost compared with the cash I would lock up to dodge it?”

What Leverage Can You Use as a Move-Up Buyer?

On a one-unit principal residence, conventional purchase leverage runs to 95% LTV (5% down) for most buyers. The 97% option (3% down, fixed rate) requires at least one first-time buyer, meaning no ownership interest in a residence in the previous three years. A move-up buyer who owns a home does not usually qualify.

Fannie Mae’s Eligibility Matrix lists maximum LTV by occupancy and unit count, and the agency’s 97% LTV FAQ explains the first-time-buyer or HomeReady condition. Two- to four-unit principal residences also reach 95%. Second homes reach 90%. If your plan involves a second home or rental, occupancy decides the leverage, and the matrix is the place to check. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.

The wholesale conventional programs start at a 620 decision score, and the automated finding governs most files with a total ratio ceiling of 50%. These are floors for the lane. Many files need more than the floor.

What Do You Give Up by Putting It All Down?

You give up liquidity. Every dollar of equity committed to the house is a dollar you cannot spend on the move, repairs, a furnace that dies in month two, or a job gap. A lower balance does not pay a plumber.

Lenders also look at what you hold after closing. Reserves, meaning the cash or liquid assets left once the loan funds, can strengthen a file, and the manual underwriting lanes tie reserve factors to the Eligibility Matrix. A buyer who drains every account to hit a target LTV may weaken a file that looked fine with a cushion.

Many buyers make the same mistake: they treat a bigger down payment as always better. It is better only up to a point. The insurance savings and the smaller balance are real. So is the risk of being house-rich and cash-poor.

When Should You Put More Down?

Put more down when a specific line sits within reach and the cash you keep is still comfortable. Skip it when the extra equity buys little and leaves you thin.

This is a genuine toss-up for buyers who sit in the middle. The insurance savings argue for putting more down. The liquidity argument says keep a buffer. The file’s strength often settles it.

One more option exists. Some buyers close with a smaller down payment and apply proceeds toward the balance later. Whether a lender allows a recast (re-amortizing the loan after a lump-sum payment) varies, so ask before you rely on it. It does not help if the loan has to fit under the conforming limit at closing.

What Happens If Your Old Home Has Not Sold?

Timing changes everything. If the old home is pending sale but will not close before the new loan, the old payment can count against you in qualifying.

Fannie Mae counts both the current and the new housing payment in qualifying, unless the file has an executed sales contract and confirmation that financing contingencies are cleared. Its guidance on other real estate owned spells out the treatment. Freddie Mac’s Guide Section 5401.2 allows the old payment to be excluded from the debt-to-income ratio (DTI, your monthly debts as a share of income) with an executed sales contract. If that contract has a financing contingency, the file also needs evidence it was cleared or the buyer’s lender commitment.

A signed contract alone is not enough. A buyer whose old home is listed but not under contract carries both payments in DTI. That can push the file toward waiting, toward using proceeds to shrink the new loan, or toward renting the old home.

A bridge or swing loan counts as a contingent liability in DTI. That requirement is waived with an executed contract and cleared financing contingencies, per Fannie Mae’s monthly debt obligations rule.

Keeping the old home as a rental is allowed in some cases. Fannie Mae’s departing residence rule requires the lender to document a current housing payment and the market rents used. The rent that counts and the reserves required depend on the file, so get the lender’s treatment in writing.

Where Move-Up Files Go Wrong

Most problems trace back to a few repeat mistakes.

• Counting gross equity as cash. Commissions, costs, and liens come out first.
• Trusting anticipated proceeds. They are an estimate until the settlement statement exists.
• Assuming a contract erases the old payment. Cleared financing contingencies are what count.
• Expecting cash back. On a purchase, Fannie Mae limits cash back to narrow cases, such as refunds of overpaid fees or prorated tax credits.
• Using interested-party money. Fannie Mae does not allow interested-party contributions toward the down payment, and undisclosed contributions are ineligible.
• Draining every account. The smaller loan is nice. The empty cushion is not.

An observation from the broker’s chair: files that stall late are rarely about the loan program. They are about a sale that slipped, a settlement statement that arrived short, or a down payment sized to projected equity that never fully showed up. Sizing to documented cash, with room to spare, prevents most of it.
