Buying a home while selling yours works when you line up three things: a purchase contract that protects you if your sale falls through, a way to cover the down payment before your current home’s equity is in hand, and a closing schedule that lets the proceeds from the sale flow straight into the purchase. Get those pieces right and the two transactions close as one coordinated event, often on the same day.
Know What Your Current Home Will Leave You
Start with a written payoff request to your current mortgage servicer. Federal law requires the servicer to provide an accurate total balance, including accrued interest and any prepayment penalties, within seven business days.1Consumer Financial Protection Bureau. 12 CFR Part 1026 (Regulation Z) – 1026.36 Prohibited Acts or Practices and Certain Requirements for Credit Secured by a Dwelling That number, subtracted from your expected sale price along with agent commissions and closing costs, is your working estimate of net proceeds.
Commissions are negotiable, and since the 2024 National Association of Realtors settlement, buyer and seller agent compensation is no longer bundled through the MLS.2National Association of REALTORS®. What the NAR Settlement Means for Home Buyers and Sellers Also budget for transfer taxes, title insurance, and property tax prorations, which get adjusted between buyer and seller based on the closing date.
The bigger financial question is whether you can qualify for the new mortgage while still carrying the old one. If your current mortgage is still on your credit report when you apply, both monthly payments count in your debt-to-income ratio. For conventional loans underwritten through Fannie Mae’s automated system, the maximum allowable ratio is 50 percent of stable monthly income. Manually underwritten loans cap at 36 percent, with room to 45 percent for borrowers who have strong credit scores and reserves.3Fannie Mae. Debt-to-Income Ratios If carrying both payments pushes you past the limit, you have two paths: use a contingency-based contract so you don’t own both homes at once, or use bridge financing that satisfies the lender the old mortgage will be paid off soon.
You’ll also need liquid cash for earnest money on the new home. Deposits range from 1 to 10 percent of the purchase price depending on local custom and how competitive the market is.4National Association of REALTORS®.

Covering the Down Payment Before Your Sale Closes
If you need proceeds from the current home to fund the new down payment, there are a few ways to unlock that cash early.
Bridge Loans
A bridge loan is a short-term loan, typically six to twelve months, that lets you borrow against your current home’s equity for the down payment on the next one. Rates run higher than standard mortgages, generally 8.5 to 10.5 percent for well-qualified borrowers, with origination fees of 1.5 to 3 percent of the loan amount. Most bridge loans require interest-only monthly payments and get paid off in full when your current home sells. The lender will appraise the departing residence and verify your income before approving.
Home Equity Line of Credit
A HELOC on your current residence lets you draw funds as needed and put them toward the new down payment or closing costs. Because it creates a second lien, you must disclose it on your new mortgage application as a source of funds, and the underwriter will factor the credit limit into your overall debt picture. When you sell the current home, the HELOC balance gets paid off automatically at closing from the proceeds.
401(k) Loan
If your employer’s retirement plan allows it, you can borrow up to 50 percent of your vested balance, capped at $50,000. You repay yourself with interest. The risk is employment: if you leave your job while the loan is outstanding, the plan may require full repayment, and any amount you can’t repay becomes a taxable distribution, plus a 10 percent early withdrawal penalty if you’re under 59½.5Internal Revenue Service. Retirement Topics Loans Use it only with a stable job and a clear repayment plan.
Recasting After the Sale
If you qualify for both mortgages and buy the new home before selling the old one, you can shrink the new monthly payment later through a mortgage recast. Once the first home sells, you make a lump-sum payment toward the new loan’s principal and the lender recalculates monthly payments against the lower balance. Recasting typically costs a few hundred dollars in administrative fees, keeps your original rate and term, and doesn’t require a credit check or appraisal. Lenders usually set a minimum lump sum, often between $5,000 and $50,000. Ask your lender before closing whether they offer it.
Contingencies That Link the Two Contracts
Contingencies are clauses in your purchase contract that let you walk away and get your earnest money back if a specified condition isn’t met. Two matter most when you’re buying and selling at once.
Home Sale Contingency
A home sale contingency makes your purchase conditional on finding a buyer for your current home. The contract sets a deadline, commonly 30 to 60 days, for you to sign a contract on your property. Miss the window and you can cancel the purchase with your deposit returned. Sellers in competitive markets are often reluctant to accept this kind of contingency because it leaves too much unresolved.
Home Close Contingency
If your current home is already under contract but hasn’t closed yet, a home close contingency (sometimes called a settlement contingency) fits better. It recognizes you already have a buyer and just need that sale to finalize. Sellers are generally more willing to accept this than a home sale contingency because there’s less uncertainty.
The Kick-Out Clause
Sellers who accept a contingent offer often insist on a kick-out clause that lets them keep marketing the property. If they receive a non-contingent offer from another buyer, they notify you in writing, and you have a short window, typically 72 hours, to either remove your contingency and commit to the purchase or step aside. Removing the contingency means you’ll buy the home whether or not your current one has sold, so you need confidence in your financing before doing it.
Appraisal Gap Clauses
In competitive markets, buyers sometimes offer above appraised value. Because lenders finance based on the appraisal, any shortfall becomes your responsibility. An appraisal gap clause commits you to cover that difference up to a set dollar amount in cash at closing. If you offer $600,000 and the home appraises at $580,000, you pay the $20,000 gap out of pocket. When you’re buying while selling, be careful how much gap you commit to, because that cash sits on top of your down payment and may depend on proceeds you haven’t received.
What Protects Your Earnest Money
A properly written contingency protects your deposit. If the deadline passes and the condition wasn’t met, you can withdraw with your earnest money returned. You forfeit the deposit if you back out for a reason no contingency covers, miss deadlines in the contract, or change your mind after contingencies have already been removed.
Closing Both Deals on the Same Day
In a concurrent closing, the sale and the purchase settle the same day, with proceeds from the first funding the second. The buyer of your current home wires funds to the title or escrow company handling that sale. That title company pays off your existing mortgage from the proceeds and wires your remaining equity to the title company managing the new purchase. The wire has to arrive the same business day, which is why both closings typically get scheduled for the morning.
Your lender must deliver the Closing Disclosure on the new mortgage at least three business days before closing. This document replaced the older HUD-1 settlement statement for most residential loans in 2015.6Consumer Financial Protection Bureau. What Is a HUD-1 Settlement Statement? It lists every credit and debit, including the exact equity being applied from your sale. Significant changes after delivery, like a shift in the annual percentage rate or the loan product, force the lender to issue a corrected disclosure and restart the three-day clock.7Consumer Financial Protection Bureau. TILA-RESPA Integrated Disclosure FAQs
The sequence finishes when the new deed and mortgage get recorded at the county recorder’s office, which establishes your legal ownership. Schedule both closings mid-week to dodge weekend bank delays, and confirm the county recording cutoff. If recording doesn’t happen before the office closes, the purchase pushes to the next business day.
Guarding Against Wire Fraud
Wire fraud aimed at real estate closings is a real and growing risk. Criminals intercept email between buyers, agents, and title companies, then send fake wiring instructions that redirect closing funds to fraudulent accounts. Once the wire goes out, the money is very hard to recover.
The Consumer Financial Protection Bureau recommends identifying two trusted individuals, such as your agent and settlement agent, and confirming the closing process and payment instructions with them by phone or in person, not by email. Verify the account name and number by calling a phone number you obtained independently, not one from an email. Don’t email your financial information, and don’t click links or open attachments from closing-related emails without confirming through a separate channel.8Consumer Financial Protection Bureau. Mortgage Closing Scams: How to Protect Yourself and Your Closing Funds If you suspect fraud, contact your bank immediately and file a complaint with the FBI’s Internet Crime Complaint Center.
If the Dates Don’t Line Up
When your sale closes before you’re ready to move into the new home, a post-sale occupancy agreement lets you stay in the home you just sold for a short period after closing. It functions as a temporary rental between you and the new owner.
The agreement sets a daily or monthly rental rate, usually calculated from the new owner’s mortgage and tax costs, and a firm move-out date, generally no more than 60 days out. A security deposit held in escrow covers possible damage and is returned after a final walkthrough. Carry renter’s insurance during this period, because your homeowner’s policy ended when you transferred title.
Overstaying is expensive. Most agreements include daily penalties that accumulate for each day past the move-out date, and the new owner can begin formal eviction if you don’t leave. Negotiate a realistic timeline upfront. If your new home’s closing date is still uncertain, build in a buffer.
Capital Gains Before You Count the Proceeds
Not all the cash from your sale is spendable. Federal law lets you exclude up to $250,000 of profit on the sale of a primary residence if you file single, or up to $500,000 if you file jointly.9Office of the Law Revision Counsel. 26 USC 121 – Exclusion of Gain From Sale of Principal Residence To qualify, you must have owned and lived in the home as your primary residence for at least two of the five years before the sale.10Internal Revenue Service. Sale of Residence – Real Estate Tax Tips You can only claim the exclusion once every two years. For joint filers, the full $500,000 requires that at least one spouse meets the ownership test and both spouses meet the two-year use test; if only one qualifies, you may still be able to exclude up to $250,000.
Profit above the exclusion is taxed at federal long-term capital gains rates of 0, 15, or 20 percent, depending on your taxable income and filing status.11Internal Revenue Service. Topic No. 409, Capital Gains and Losses If any portion of the home was used for rental or business purposes, part of the gain allocable to that nonqualified use may not be excludable. Estimate the tax before you decide how much of your net proceeds you can commit to the new purchase.
