Can You Sell Your Home and Buy Another One at the Same Time in Southlake?

Yes, and in Texas you have three main paths: a sale contingency using the TREC Addendum for Sale of Other Property, a bridge loan or HELOC that funds your purchase before your sale closes, or a leaseback where you sell first and rent the home back for a short window while your next one closes. In Southlake's tight, competitive inventory, the leaseback has become the most common clean path for move-up families with strong equity. The right approach depends on your equity position, how competitive your target home is, and how flexible your timing is.

The question I hear most from families in Southlake isn't "should we move?" They've already decided that. It's this: "How do we actually do both at the same time without losing the next house or getting stuck carrying two mortgages?"

That's a legitimate concern. Coordinating a simultaneous sell-and-buy is one of the more complex real estate transactions there is. It also happens every day in this market when it's planned correctly.

Why This Feels Harder Than It Should

When you sell a home and buy another one at the same time, you're managing four moving timelines at once: the listing, marketing, and sale of your current home, the search, offer, and negotiation on the next one, the financing for the purchase, which depends on your current home's equity, and the closing coordination between both transactions.

Any one of those can slip. The families who get this right don't do it by luck. They choose a transaction structure that accounts for the gap between the two closings before that gap becomes a problem.

That matters even more in Southlake, where serious buyers compete for a genuinely limited supply of homes. If you want a deeper look at how that competition plays out in practice, our breakdown of winning a multiple-offer situation in Southlake is worth reading before you tour.

Three Ways to Bridge the Gap

There isn't one right answer here. The right tool depends on your equity, your lender, and how competitive the home you're buying actually is.

• A sale contingency. Texas has a specific contract form for this: the TREC Addendum for Sale of Other Property. There are two versions, and the difference matters. A Home Settlement Contingency is used when your current home is already under contract, which is the stronger version since the seller knows there's a defined closing date coming. A Sale and Settlement Contingency is used when your home isn't yet under contract, and most sellers will attach a kick-out clause that lets them keep marketing the home and accept a backup offer. In Southlake's current market, contingent offers face real resistance, though a home that's priced right and ready to move changes the calculus.
• A bridge loan or HELOC. If you have equity in your current home and want to make a clean, non-contingent offer, a bridge loan or home equity line of credit can fund your down payment before your sale closes. Bridge loans typically carry higher rates and shorter terms, paid off once your current home closes. A HELOC generally runs cheaper, but it has to be opened while you still own your current home, you can't open one after you've listed it, and definitely not after you're under contract. If this is your likely path, set it up early. Either option means carrying two payments for a stretch, so budget for that rather than getting surprised by it at closing.
• A leaseback. This is the most commonly overlooked option, and often the cleanest path available to Southlake move-up families with strong equity. You sell your current home and close the sale, then negotiate a leaseback agreement with the buyer so you can stay in the home for a set number of weeks, paying rent typically pegged to the buyer's mortgage payment. Once that sale closes, your proceeds are confirmed and you can make a non-contingent offer on the next home backed by real money in hand. At Southlake's price point, buyers tend to be more deliberate, and a 30 to 45 day leaseback is a reasonable ask, though it's a negotiation, not a guarantee.

Most of the families I work with in Southlake end up combining elements, for example lining up a HELOC as a backstop while also negotiating leaseback flexibility with their buyer. Having more than one lever available is what keeps a transaction from becoming stressful.

How Your Search Should Change When You're Doing Both at Once

Buying casually and buying while you're also selling are two different searches, even though they look the same on a real estate app.

When you're doing both together:

• Get pre-approved, and get your equity number confirmed, before you start touring. A synchronized move needs to move fast once the right home shows up, and knowing your real equity position up front is what lets you decide between a contingency, a bridge loan or HELOC, and a leaseback before you're under pressure to choose.
• Know your non-negotiables before you start. If Carroll ISD boundaries, lot size, or a specific price ceiling matter to your family, decide that up front. Southlake's inventory doesn't leave much room for a slow, exploratory search.
• Have your current home's timeline mapped before you tour. If you already know roughly when your listing goes live, or how competitive your price point is likely to be, you can evaluate every new home against that calendar instead of falling for a house you can't actually time correctly.

Every buyer we walk through this process starts with the same coordinated approach outlined on our step-by-step buying and selling guide.

What Closing Actually Looks Like in Tarrant County

Southlake sits primarily in Tarrant County, most of it served by Carroll ISD. Texas is a title-company-closing state rather than an attorney-closing state, so your timeline runs through title company scheduling, which typically moves faster than attorney-calendar states.

A few things worth knowing before you're under contract:

• Homestead exemption timing matters. If you close on your new home in the same tax year, make sure your homestead exemption filing is handled correctly so you don't end up with a gap in your property tax benefit.
• Property tax proration at closing is standard practice, but double-check how it's calculated if you're closing near a MUD or PID district boundary, since assessed rates can shift the numbers more than buyers expect.
• Your lender needs to underwrite both transactions together, not as two separate files handled by two different loan officers. This is one of the most common places a synchronized move falls apart, and it's worth confirming up front that your lender has actually done this before.

For the seller side of the math, our breakdown of what you'll net selling your Southlake home and our Southlake property tax guide both cover pieces of this in more depth.

The Part That Doesn't Show Up on a Closing Timeline

The financing and the paperwork are the easy part to plan for. What's harder to plan for is your family living through two transactions at once while everyone still has to get to school and work on time.

This is exactly the kind of situation where having one person coordinating both sides, instead of juggling two agents or two separate processes, changes how the whole thing feels. Every situation is different, and the only way to know which bridge strategy actually fits your numbers is to run them with someone who's done this before.

Frequently Asked Questions

Can I make an offer on a new home before my current home sells?

Yes, through a sale contingency using the TREC Addendum for Sale of Other Property, or by securing bridge financing that lets you close without waiting for your sale to complete.

What's the difference between a bridge loan and a HELOC?

A bridge loan is a short-term loan for the transition period, typically at a higher rate with an origination fee. A HELOC is a line of credit against your existing equity, generally cheaper, but it has to be set up before you list your home for sale.

How long can a leaseback last in Texas?

Most leasebacks run 30 to 60 days, though some buyers will agree to longer depending on their own timeline and financing situation. It's fully negotiable as part of the sale contract.

Will sellers accept a contingent offer in a competitive market like Southlake?

It's harder, but not impossible. A Home Settlement Contingency, where your home is already under contract, is far more palatable to sellers than a Sale and Settlement Contingency with a kick-out clause.

What happens if my home doesn't sell in time?

This is exactly why bridge loans, HELOCs, and leasebacks exist. They decouple your purchase timeline from your sale timeline so a slower-than-expected sale doesn't put your new purchase at risk.
