Updated October 2026. How to pay for the overlap when you buy before your current home sells: bridge loans, HELOCs, sale contingencies and rent-backs, using Fannie Mae’s Selling Guide and CFPB guidance read October 29, 2026.
To buy a new home while selling yours, you need a way to cover the gap between the two closings. The four common tools are a bridge loan, a HELOC on your current home, a home-sale contingency and a rent-back. As of October 2026, Fannie Mae counts both house payments when you qualify unless your current home has a signed contract with financing contingencies cleared.

Key takeaways
- Without a signed sale contract, a Fannie Mae lender includes your current payment and your new one when it qualifies you.
- If your home is listed but not under contract, a lender can estimate proceeds as 90% of the list price minus all liens.
- Fannie Mae accepts a bridge loan as a source of funds only if it isn’t cross-collateralized against the new home.
- A HELOC lender can freeze or cut your line if your home’s value drops or your finances change (CFPB).
This guide is about the money: how each option works, what it costs and when it fits. If you’re still deciding whether to sell first, buy first or close both on the same day, read How to Sell and Buy a House at the Same Time Like a Pro first.
Can you qualify for a new mortgage before your home sells?
Yes, but the lender will look at both homes. Fannie Mae’s Selling Guide (B3-6-06) says that if your current home is pending sale but won’t close before the new loan, the lender uses both your current and your new housing payment to qualify you. The exception: if you provide the executed sales contract and proof that the buyer’s financing contingencies are cleared, the old payment can drop out.
The down payment is the other half. Under Fannie Mae’s anticipated sales proceeds rule (B3-4.3-10), a lender can qualify you on the equity you expect from a home that’s listed but not sold:
| Situation | How Fannie Mae estimates proceeds | Example: listed at $450,000, $250,000 owed |
|---|---|---|
| Sale price set (under contract) | Sale price minus sales costs and all liens | Sold at $440,000 with $20,000 in costs: $170,000 |
| No sale price yet | 90% of list price minus all liens | $405,000 minus $250,000: $155,000 |
If you need that money for the new down payment and closing costs, the lender must see the settlement statement from your sale before, or at the same time as, the new closing. That’s why many buyers line up the two closings back to back.

How does a bridge loan work?
A bridge (or swing) loan is short-term financing secured by your current home. You use it for the new down payment and repay it when your old home sells.
Fannie Mae accepts a bridge loan as a source of funds for the new purchase if two things hold (B3-4.3-14):
- The bridge loan isn’t cross-collateralized against the new property.
- The lender documents that you can carry the payments on the new home, the current home, the bridge loan and your other debts.
Fannie Mae sets no limit on the bridge loan’s term. Your bridge lender will set its own, along with its own rate and fees, which are often higher than a regular mortgage. A bridge works best when you have plenty of equity and you’re confident the old home will sell soon. National data helps you judge “soon”: NAR says homes sold in September 2026 spent a median of 33 days on the market, but your price point and area can differ a lot.
Should you use a HELOC on your current home?
A home equity line of credit lets you borrow against your current home’s equity, often at a lower cost than a bridge loan. The CFPB describes it as an open-end line you can draw on during a draw period (for example, 10 years), with minimum payments based on your balance.
Two catches matter for movers:
- Timing. Open the line before you list. A lender may decline to open a HELOC on a home that’s already for sale, so ask first.
- Freezes. The CFPB says a lender can stop you from drawing more if your home’s value drops significantly or your finances change.
Also ask about fees, minimum draws and any early-closure charge. You’ll pay the line off from your sale proceeds at closing, so a fee for closing it in the first few years can bite.
What about a home-sale contingency?
A home-sale contingency makes your purchase depend on selling your current home by a set date. It costs nothing in interest, which is its big appeal. The trade-off is that sellers often see it as a weaker offer, especially if they have other buyers.
To make one more acceptable:
Sell smarter
List your home on the MLS from $99
A flat fee instead of a percentage, and $0 to Beycome at closing. You stay in control of your sale.
Sell your home →Buy smarter
Get up to 2% back at closing
On homes listed by other agents, Beycome credits you up to 2% of the price at closing (1% kept, $1,499 minimum; not on FSBO homes or homes listed by Beycome sellers).
Buy a home →- List your home before you make the offer, or better, have it under contract already.
- Keep the deadline short and specific.
- Offer a “kick-out” clause so the seller can keep marketing and ask you to remove the contingency if a new offer arrives.
- Show your pre-approval and your home’s listing details with the offer.
Have a real estate attorney or your agent check the wording. Our guide to real estate disclosures covers what you’ll owe your own buyer on the selling side.
How does a rent-back help, and what does it cost?
A rent-back (or post-closing occupancy) lets you sell and close first, then stay in your old home for a short time while you close on the new one. You get your equity in cash before you buy, which makes your purchase simpler.
What it costs is negotiated. Expect to agree on:
- A daily or monthly rate, often based on the buyer’s new housing cost.
- A deposit held at closing to cover damage or a late move-out.
- Who insures what: the buyer insures the house; you insure your belongings.
- A firm move-out date and a penalty for staying late.
Put it in a written occupancy agreement. If the buyer has a mortgage, their lender may limit how long you can stay, so ask early.
Which option fits your situation?
| Option | Best when | Main cost | Main risk |
|---|---|---|---|
| Bridge loan | Lots of equity, quick sale expected | Interest and fees | Carrying three payments if the sale drags |
| HELOC | Time to open it before listing | Interest on what you draw | Line frozen or cut |
| Sale contingency | Slower markets, flexible sellers | A weaker offer | Losing the house to another buyer |
| Rent-back | You can sell first | Rent and deposit | A tight move-out date |

Buying while selling: questions
Can I buy a new house before selling my old one?
Yes, if you qualify with both payments or use a bridge loan, HELOC or sale contingency. A signed sale contract with financing contingencies cleared can let a Fannie Mae lender drop your old payment.
How much of my equity can a lender count before I sell?
Under Fannie Mae’s rule, 90% of the list price minus all liens if there’s no contract yet, or the sale price minus costs and liens once there is.
Is a bridge loan or a HELOC cheaper?
A HELOC can be cheaper, but it’s best opened before you list. Compare the full cost of each in writing.
Will a seller accept a home-sale contingency?
Some will, especially in slower markets. A short deadline, a kick-out clause and a home already under contract make it easier.
What is a rent-back after selling a house?
An agreement to stay in your sold home for a set time after closing, usually for a daily rate and a deposit.
Can I close on both homes the same day?
Often, yes. Sell in the morning and buy in the afternoon, with your lender seeing the sale’s settlement statement first.
