Selling and Buying at the Same Time
Almost every move-up buyer faces the same problem: the money is in the current house. Here are the four ways people solve it.

The core tension is timing. Sell first and you may need somewhere to live; buy first and you may carry two payments. Every solution is a trade between cost and certainty.
Option 1: sell first, then buy
Financially the safest route. You know your exact proceeds, you shop as a non-contingent buyer, and you carry one payment. The cost is interim housing and possibly two moves.
A rent-back — where the buyer of your home lets you remain for a few weeks after closing — solves most of this. Negotiate it into the contract, and expect to pay something close to the buyer's daily carrying cost.
Option 2: buy first with a home sale contingency
Your purchase is contingent on your current home selling. This protects you but weakens the offer considerably; in any competitive market it will usually lose to a clean offer.
Option 3: bridge financing
A short-term loan against your current home's equity funds the down payment on the next one. It buys certainty at a cost: higher rates, origination fees, and the risk that your home takes longer to sell than expected.
Option 4: borrow against equity before listing
A HELOC opened before you list can serve a similar function at lower cost. The catch is that lenders generally will not open one on a home already listed for sale, so this has to be arranged in advance.
| Approach | Cost | Certainty | Best when |
|---|---|---|---|
| Sell first + rent-back | Low | High | You can negotiate a rent-back |
| Contingent offer | Low | Low | Slow markets with motivated sellers |
| Bridge loan | High | High | Competitive market, strong equity |
| HELOC arranged early | Medium | High | You planned several months ahead |
Frequently asked questions
Can I use my current home's equity for the next down payment?
Yes, either through the sale proceeds at closing, a bridge loan, or a HELOC opened before you list.
What is a rent-back agreement?
The buyer takes ownership at closing and the seller stays for an agreed period, usually paying a daily rate. Sixty days is a common maximum, as longer periods can affect the buyer's owner-occupancy financing terms.
