Moving Up: Selling Your Home and Buying Another

Avoid getting stuck paying two mortgages when buying your next house.

By , J.D. · University of Washington School of Law

If you plan to sell your home and buy another, which should you do first? If you sell first, you'll be under time pressure to find another house quickly—and could end up settling for less than you wanted, overpaying, or having to stuff yourself and all your possessions into a hotel room until you can buy a new place. But, if you buy first, you'll have to scramble to sell your old house—a particular problem if you need to get top dollar on the sale in order to make the down payment on the new one.

Owning two houses at once is no treat, either, even if it's for a short time. You'll have to worry about two mortgages—in the unlikely event that a lender is even willing to offer you a mortgage for a second house before you've sold the first—as well as twice the maintenance, and the security issues that come with leaving one house empty.

Here are ways to minimize the financial and psychological downsides of selling one house while trying to buy another.

Take the Housing Market's Temperature

Before putting your house on the market or committing to buying a new one, investigate the prices of houses in the areas where you'll be both selling and buying. In order to figure out how to sell high and buy low, you'll need a realistic idea of how much comparable houses are going for.

Also focus on whether the local real estate market is "hot" (favors sellers) or "cold" (favors buyers). Since you're both a buyer and a seller, you'll need to protect yourself in your weaker role while making the most of your stronger role.

Strategies in a Buyer's Real Estate Market

When the market is cold, you're in a stronger position as a buyer than as a seller. You've probably got your pick of lots of houses for sale, at reasonable prices. But you might have trouble selling yours. To protect yourself, you might start by buying a second house, but then ask the seller to make your purchase contract contingent upon your selling your current home. A seller having a hard time finding a buyer is likely to accept this contingency, even though it means waiting for you to find a buyer. Be ready to give the seller plausible reasons why your home will likely sell quickly.

In case no seller is willing to accept this contingency, however, at least make sure you can arrange financing. Talk to a mortgage broker about what you'll qualify for. Then be ready to act quickly to put your first home on the market after going ahead with buying a second one. There's a lot you can do ahead of time, such as taking care of maintenance issues, going through files for the appliance manuals and other documents you'll give the buyer, choosing a real estate agent and possibly a home stager, and so forth.

Strategies in a Seller's Real Estate Market

In a hot market, selling your house will likely be easier than buying a new one. To make sure you don't end up house-less, you might want to start by looking for a house to buy, then line up enough cash—using the strategies described below—to tide you over during the presumably short period where you own two houses at once.

If you can't swing such an arrangement, however, you can negotiate with your house's buyer to have the sale contract include a provision making the closing contingent on your finding and closing on a new house. Although few buyers will agree to an open-ended period, some will be so eager to buy your house that they'll agree to delay the closing until you close on a new house or until a certain number of days pass, whichever comes first.

Also be sure to fully research the market before you sell, so that you'll be an efficient buyer, who is able to offer the right price on attractive terms.

Bridge Financing: How to Own Two Houses Briefly

What if you're unable to perfectly dovetail the sale of one house with the purchase of another? You could own no houses for a time, in which case you'll have money in the bank and will need a temporary place to live. Or you could own two houses at once. The following suggestions should help you deal with such juggling acts:

Borrow down payment money for the second house from family or friends

If you have family members who have sufficient spare cash to make investments, them lending you money could serve both their interests and yours, particularly if you offer to pay a competitive interest rate. Point out that you need help for only a short period, as well. Give the person making the loan a promissory note, secured by a second mortgage (deed of trust) on your new house. Try to arrange it so that no monthly payments are due until your first house sells. Be warned, however, that depending on your financial situation, institutional mortgage lenders might refuse to approve a loan where the down payment doesn't come from your own resources.

Get a bridge loan from a financial institution

If you have no other choice, it could be possible to borrow money from a bank or other lender to bridge the period between when you close on your new house and when you get your money from the sale of your old one. This idea is that you take out a short-term loan on your existing house, using it toward the down payment and closing costs on your new house, and repaying it when your first house sells.

Bridge loans can, however, be far more expensive than regular mortgage or home equity loans (higher upfront payments as well as interest rates), and they're not easy to qualify for. You'll need plenty of equity in your current home and enough income to pay both mortgage payments indefinitely. The requirements all but negate the benefits of the loan.
