How to Buy a House Before Selling Yours: 7 Options Compared

The answer is yes if you can solve these two items. The first is qualifying while your current home is on the market, since the lender counts that payment on top of the new one without letting your debt-to-income ratio go past what the loan allows. The second is cash, since your equity is locked in the old home until it closes.

Every option below solves one of those problems, and a few solve both. Before you tour anything, get a pre-approval that counts both payments, so your loan officer can tell you which paths are open.

Yes. No rule limits you to one mortgage, but under Fannie Mae's Selling Guide (B3-6-06) the lender counts both full payments until the old home's sale is nearly done. That takes an executed sales contract plus proof that your buyer's financing contingency has cleared. A listing doesn't qualify, and neither does a pending sale whose buyer is still waiting on loan approval.

FHA adds a hurdle of its own if your current home has an FHA loan: it insures only one primary residence per borrower, with narrow exceptions such as a job move of more than 100 miles.

A worked example: qualifying with both mortgage payments

Take one made-up household with round numbers. They earn $12,000 a month before taxes, and their current home's full payment (principal, interest, taxes, insurance and any HOA dues, or PITIA) runs $2,500. Their new mortgage payment would be $3,800.

Carrying both lands near 60%, higher than conventional or FHA automated approvals usually go, and equity doesn't move that number. Regardless of equity position, the entire mortgage payment has to be considered until a property is sold or rented.

The contract path is the strongest, because the old payment drops out entirely. Renting helps less than people expect: the lender counts 75% of the rent, so this house would need about $3,333 a month in rent before its payment stopped counting against the buyers.

Renting out your current home to qualify

You can keep the old house and use its rent, but Fannie Mae rewrote the rule in September 2026. Under its departing residence guidelines, a signed lease no longer counts; the rent comes from the appraiser's market rent schedule (Form 1007) or market data with at least three comparable rentals.

The lender takes 75% of that rent and subtracts the old home's PITIA. A negative result goes into your debts. A positive one only cancels the old payment, even if you've been a landlord before, and first-time landlords also need six months of the vacated home's payment in reserves.

Freddie Mac and FHA still work from a lease. Freddie uses 75% of the lease rent. FHA counts rent from the home you're leaving only if you're moving more than 100 miles away, and a house with no rental history also needs 25% equity.

Setting a buying budget for the overlap

When waiting for the home to sell there will be costs for two mortgages. You will need to budget for mortgage payments, interest, lights and other household expenses that occur.

Allow yourself six months of cushion, this comes from Fannie requirement for a first time landlord. In the example above, that's $15,000 for the old payment alone, before any HELOC or bridge interest. If that would drain your savings, sell first.

You will need to consider the monthly occurring amounts. Use a worst-case scenario when creating a budget, such as, net floor for the sale, and lowest rent amount counted. Run both payments through the affordability calculator and the new loan alone through the mortgage calculator.

The table shows which problem each option solves.

Can you use a HELOC to buy another house?

You can use a HELOC as a second mortgage on your current primary residence for a down payment on another home. Fannie Mae accepts money borrowed against your own real estate as down payment funds (B3-4.3-15), but the line's payment joins your debts, and if none is due yet, the lender estimates one.

Before you list the property for sale you will need to open the home equity line, since lenders won't open one on a home that's already listed. A HELOC will require its own appraisal.

Lump sums and home equity loans work the same at a fixed rate when a buyer knows the exact down payment they need. A line of credit suits someone who doesn't, and our comparison covers the difference.

Another way is a cash-out refinance, which can raise the same amount of money at a higher cost. It will replace your first mortgage with a full set of closing costs. In Texas, all of these fall under the homestead limits below.

Using a bridge loan to buy a house before selling

A bridge loan can cover the gap of your own home and down payment before the current home closes on its sale. It is only considering a short-term financing secured by the current home. Federal truth-in-lending rules (Regulation Z) use this exact case as their bridge loan example: 12 months or less, while the old home sells.

In November of 2026 bridge loans lent up to about 80% of the value of the current home for up to a year. These were interest-only payments, but the rates will run higher than your regular mortgage and they carry fees.

The bridge loan will count in the DTI until your current home is under contract and financing is cleared (Fannie B3-6-05), and Fannie won't accept bridge money secured by the new house. Time can be the risk if the home sits past the bridge loan term, if the price gets cut or you refinance with three payments due each month.

STX Lending arranges bridge financing through several bridge loan lenders, including a commercial option, and terms depend on the lender and the property.

How does a buy before you sell program work?

The equity in your current home is fronted by a company; this way you can make an offer with no sale contingency and list the home. If the home does not sell within six months the company will buy it at the backup price you agreed on up front below market value. Other names for this are trade-in programs and guaranteed offers.

The programs fees that were noted November 2026 ran from 1% to 2.25% of the home's value, some charge monthly on the advance, and the agent commission still comes out of the sale.

On a $400,000 house, a 2% fee is $8,000, so price it against a bridge loan for the same months. Coverage is limited to certain states or cities.

It does not cost extra to make an offer with your home sale on contingency. This is because you won't own two homes at the same time. The deal is over if it does not sell.

Sellers that do accept the contingencies can in most states accept a backup offer in the purchase contract. This is because there is more risk for sellers to accept contingencies because if your home does not sell, the seller's home will not sell as well.

To strengthen your offer, have a plan! List your departing residence before making an offer, or, better yet, have the property under contract and indicate as such in the pre-approval.

As long as you are able to carry both mortgages for about six months without a sale, or when your home comes under contract. If you are not able to do this then sell your home first. Buying and selling a house at the same time comes down to which side closes first, and your local market usually decides that.

When buying first fits your market conditions

When the contingent offer loses and homes are selling fast in area and the home you want is not going to wait for yours to sell. You also move once instead of twice. Plenty of equity makes it safer, since it funds the down payment and leaves room to cut the old home's price if it sits.

When selling first is safer in a slow housing market

Sell first when homes near you are sitting. A slow market can mean months of double payments and a lower price at the end.

Selling first doesn't have to mean moving twice. Ask your buyer for a rent-back agreement, where you close the sale and stay on as their tenant for a set stretch, so you shop with the money in your account. In Texas that's TREC's Seller's Temporary Residential Lease, for stays of up to 90 days after closing. If it runs out before you find the next house, temporary housing such as a month-to-month rental fills the gap.

Texas limits borrowing against the home you live in through its constitution, and the limits bite exactly when a move-up buyer needs cash. Any loan that pulls equity out of your homestead, a Texas cash-out refinance included, follows Article XVI, Section 50 of the Texas Constitution.

Section 50(a)(6) and HELOC limits on your homestead

The rules that matter for a buy-first plan:

• All debt on the homestead, the new loan included, can't exceed 80% of its fair market value on the day the loan closes.
• Closing can't happen until the 12th day after you apply or get the lender's required notice, whichever is later, and you then have three days to cancel.
• One of these loans per homestead every 12 months.
• It can't be secured by any other property, so the new house can't back it.
• On a HELOC, each draw must be at least $4,000.

On a $400,000 home with a $220,000 mortgage balance, the cap leaves room for $100,000 at most. Start about a month before you need the money, because the waiting periods and the appraisal run back to back. The home equity calculator runs the cap on your numbers, and our Texas HELOC guide covers the rest.

These limits follow the home you live in, which is the frustrating part of the timing. Once you've moved out and rented the old house, it's no longer your homestead (Tax Code 11.13 allows one residence homestead exemption a year), but by then you've already needed the down payment. If the 12-day wait won't fit your contract dates, look at a bridge loan instead, and ask the lender how it's secured, because the constitution limits which liens can sit on a homestead.

The TREC addendum for a home sale contingency

In Texas, a sale contingency goes on TREC's Addendum for Sale of Other Property by Buyer (form 10-6). Your sale proceeds have to arrive by a date you fill in, which the form says should fall no later than closing. If they don't, the contract ends and your earnest money comes back.

The kick-out is in paragraph B. If the seller accepts another written offer and notifies you, you have the number of days written into the form's blank to waive the contingency, or the contract ends. The form sets no default, so negotiate that number with your real estate agent. You'll want enough days to line up a bridge loan or draw on a HELOC that's already open.

You have to have a written notice and more earnest money to waive. You will be in default if you waive and then can't close because the current home money has not come in yet.
