Should You Buy Your Next Home Before You Sell? Run the Overlap First

CENTURY 21 HomeStar

By Elliot Stone | The Stone Team

Buying first can make a move easier. It can also put you in a spot where you have to take an offer on your current home because you need the money by a certain date.

My advice: buy first only if your lender confirms the financing and you can handle the overlap without counting on a fast sale at your ideal price. If the purchase depends on money from your sale, build the plan around that fact before you start making offers.

First, find out what the lender is counting on

Ask your lender one plain question: “Can I close on the next home if my current home hasn't sold yet?” Then ask whether the answer depends on selling, having a signed contract, clearing a contingency, or bringing a down payment from another source.

For example, Fannie Mae's guide generally requires lenders to count both housing payments when a financed primary home won't transfer before the new purchase. It provides an exception under specific documentation conditions. Ask what your lender needs for your loan; an accepted offer on your current home does not automatically mean its payment can be left out. [1]

Run two numbers: cash to close and the cost of waiting

Start with a seller's net sheet. Your expected sale price isn't what you can spend on the next house. The net sheet subtracts the estimated payoff and selling costs, and it should tell you what you expect to have after the sale closes.

Then build a separate overlap budget. Include housing payments, insurance, utilities, upkeep, moving expenses and any storage. Keep the purchase's cash to close separate from the money you need to carry both homes. Ask the lender to confirm the down payment source and what you'd need at closing. [2]

Here's a simple example, with made-up numbers: If keeping your old house costs you $2,000 a month after you've moved, three extra months cost $6,000, before any surprise repairs. Compare that with what you'd spend on a short rental, storage and a second move if you sold first. The better choice depends on your numbers and how much uncertainty you can afford.

Pick the plan that still works if a closing moves

• Sell first. If you need your sale proceeds or have little room for two payments, this is where I'd start. Price a temporary rental, storage or another place to stay before you commit. If you want to stay after closing, get the buyer's agreement in writing and have your agent and lender check whether the arrangement works.

• Make the purchase depend on your sale. If the seller will accept it, have your agent walk you through what has to happen, by when, and what happens if your sale falls through. Get the terms in writing. Don't assume a contingency protects you from every delay or lets you cancel whenever you want.

• Buy first with a cushion. If your lender confirms you can close and you can carry both homes, decide in advance how long you'd keep the old one and what you'd do if offers are weaker than expected. If a lender proposes a bridge loan, ask for the total cost, repayment deadline, and options if your sale is late. Fannie Mae permits bridge funds subject to conditions, including documentation of the ability to carry the payments; availability and terms depend on the loan and lender. [3]

You can also aim for closely spaced closings. Ask both title teams when sale proceeds will actually be available and what happens if funding is delayed. I wouldn't schedule movers or promise possession based on two dates penciled onto a calendar.

Work backward from the move you can afford

Before touring seriously, write down three things: when you need to move, how much cash you need from the sale, and how many months of overlap you can afford. If selling sooner matters, the sell-soon guide can help you decide what to handle first.
