Buy Before You Sell in Austin: Bridge Options for Move-Up Buyers
If you already own a home in Austin and want your next one, you face a timing puzzle that renters never deal with: how do you buy the new place before the old one sells? Austin-Area MLS data reported by the Austin Board of Realtors showed a median of roughly 60 days on market for the metro in spring 2026, which means a move-up buyer can be carrying real uncertainty for two months or more. The good news is that you rarely need an exotic product to solve this. Most move-up buyers in Central Texas pull it off with Conventional financing and a few well-timed decisions. Here is how that works, where a bridge loan fits, and when each path actually saves you money.
Key points:
- Most move-up buyers qualify to carry both the old and new mortgage at once, as long as the combined debt-to-income ratio stays under about 45% to 50%.
- A bridge loan is short-term financing secured against your current home; it is fast but usually carries a higher rate and added fees.
- A contingent offer (buy only if your current home sells) costs you nothing extra but is weak in a competitive Austin bid.
- Rent-back agreements let you sell first and stay in the home for up to 60 days while you close on the next one.
- A mortgage recast after your old house sells can lower the new payment without a full refinance, for a fee around $250 to $500.
- Mortgage Austin originates Conventional, VA, and FHA loans, so the strategies here center on those, with bridge products covered honestly for comparison.
Can you buy a new home in Austin before selling your current one?
Yes, in most cases. If your income supports both mortgage payments at the same time, a lender can approve you to buy the new home while you still own the old one. The deciding number is your debt-to-income ratio (DTI), the share of gross monthly income that goes to debt. When both housing payments fit under roughly 45% to 50% DTI, you do not need a bridge loan at all.
The wrinkle is that many move-up buyers cannot comfortably carry two full payments. That is where the strategies below come in. At Mortgage Austin we usually start by running your numbers both ways: qualifying with the old home still on the books, and qualifying as if it is already sold under contract. Those two scenarios tell you which doors are open.
How do move-up buyers handle buy-before-you-sell with conventional tools?
The most common path is a straightforward Conventional purchase where you qualify carrying both payments, then pay down the new loan once your old home sells. If your DTI is too high to carry both, lenders can sometimes count the future sale: with a signed contract on your current home and reasonable proof the sale will close, the departing residence payment can be excluded from your DTI.
Three conventional tactics do most of the work:
- Qualify on both payments. Cleanest route. No second loan, no bridge fees, one closing.
- Sell with a rent-back. You close the sale of your current home, then lease it back from the buyer for up to 60 days. You get your equity in cash and a cushion to close on the next house.
- Recast after the sale. Buy the new home with whatever down payment you have, then apply the proceeds from the old sale as a large principal payment and recast. The lender re-amortizes the loan at the same rate, lowering your payment without a refinance.
What is a bridge loan and when does it make sense?
A bridge loan is short-term financing, usually 6 to 12 months, secured against the equity in your current home so you can use that equity for the down payment on the next one before the sale closes. It solves the cash-timing problem fast. The trade-off is cost: bridge loans typically carry higher rates than a Conventional first mortgage, plus origination fees, and you are temporarily carrying three obligations (old mortgage, bridge, new mortgage).
Mortgage Austin does not originate bridge loans, and for a clear reason: for most Austin move-up buyers, a Conventional approach closes faster, costs less, and removes a layer of risk. A bridge loan earns its keep in narrow cases: you have strong income but your equity is locked in a home that has not sold, the new purchase is competitive and cannot be contingent, and you are confident the old home will sell quickly. If that is your situation, the honest move is to compare a bridge quote against the conventional options side by side before committing.
Bridge loan vs. conventional move-up strategies
| Approach | Typical cost | Speed | Best when |
|---|---|---|---|
| Qualify carrying both payments (Conventional) | Standard rate, one set of closing costs | Normal close (about 21 to 30 days) | Income supports both mortgages at once |
| Contingent offer | No extra cost | Depends on your sale | Buyer’s market, low competition |
| Sell with rent-back | Rent paid to the buyer, up to 60 days | Normal close | You want equity in hand before buying |
| Bridge loan | Higher rate plus origination fees, three payments briefly | Fast | Equity is locked and the offer cannot be contingent |

How does a contingent offer work in a competitive Austin market?
A contingent offer says you will buy the new home only if your current home sells first. It protects you from owning two houses, and it costs nothing. The downside shows up in a multiple-offer situation: a seller comparing your contingent offer against a clean one will usually take the clean one. In the spring 2026 Austin market, where inventory loosened from the lows of 2022 to 2023, contingent offers became more workable than they were a few years ago, but they are still the weaker hand on a desirable listing.
The timeline that keeps it simple
When buyers ask me to map this out, the sequence usually looks like this:
- Get fully underwritten on the new purchase, with your loan officer modeling both the “still own the old home” and “old home under contract” scenarios.
- List your current home, or line up a buyer, before you go under contract on the new one when you can.
- Negotiate a rent-back or a closing date that gives you a few days of overlap, not a few weeks of double payments.
- After the old home sells, recast the new loan to bring the payment down.

Frequently Asked Questions
Do I need a bridge loan to buy before I sell in Austin?
Usually not. If your income supports both the old and new mortgage payments under roughly 45% to 50% debt-to-income, you can buy with a standard Conventional loan and pay the old loan off when your home sells. Bridge loans are reserved for cases where your equity is locked and the new offer cannot be contingent.
Can a lender ignore my current mortgage if my home is under contract?
Sometimes. With a signed sales contract on your departing residence and reasonable proof the sale will close, a lender can exclude that payment from your debt-to-income ratio. Requirements vary, so confirm the documentation your underwriter needs before you make an offer.
What is a rent-back agreement?
A rent-back lets you sell your home and then lease it from the new owner for a short period, often up to 60 days. You collect your equity at closing and gain time to close on your next home without paying two mortgages at once.
How much does a mortgage recast cost?
A recast fee is typically around $250 to $500. After your old home sells, you apply the proceeds as a large principal payment and the lender re-amortizes the loan at your existing rate, which lowers the monthly payment without a full refinance.
Is a contingent offer a bad idea in Austin?
It depends on competition for the home. A contingent offer costs nothing and protects you, but on a popular listing a seller will usually choose a non-contingent offer. As Austin inventory loosened through 2026, contingent offers became more workable than they were at the market’s peak.
How long does it take to close a move-up purchase?
A standard Conventional purchase generally closes in about 21 to 30 days once you are under contract. Coordinating the sale of your current home with a short overlap or a rent-back keeps you from carrying two payments for long.
