1. Know what you can afford--and stick to your budget. This is true of any market, of course. But when there are lots of houses on the market, it can be easy to slip into the mindset that any home is yours for the taking: “Another bedroom might be nice, or a family room and a great room….”

Don’t treat your local housing market like an all-you-can-eat buffet. Before you shop for a home, know your needs and your budget, and focus on homes that fit those. To track your spending, try the free budget planner spreadsheet from Spreadsheets123.

2. Get preapproved. This is a good idea whenever you shop for a home, buyer’s market or not. Preapproval means that a lender has given you the green light to borrow a certain amount of money before you start shopping. It helps you know how much home you can afford, and it also streamlines the mortgage application process. And it signals to sellers that you can follow through on your offer—a big bonus at a time when mortgages are tough to get.

3. Work with a buyer’s agent. A buyer’s agent represents you and your interests exclusively in a real estate transaction. If you don’t have an explicit buyer’s agency agreement, your agent may actually be working for the seller. If you’re not sure that your agent is a buyer’s agent, ask. You need to be sure that your agent works for you, 100 percent.

4. Negotiate your agent’s commission. Real estate agents earn their money by commission, and that means they get paid only when they sell a home. In a buyer’s market, when sales are sluggish, your agent may be willing to return a portion of her commission to you as a rebate at closing. Why? Agents waste a lot of time working with window-shoppers who never make an offer. A rebate may induce you to follow through and buy a home.

5. Do your research. Before you make an offer, spend some time looking at similar properties that have sold in your area recently (the last six months), called comparables or comps. (Your real estate agent can get you the most recent data.) If selling prices are consistently lower than list prices, you’ve got a good chance of having a lower-than-list-price offer accepted.

6. Use online resources. Thanks to the Internet, it’s easier than ever before to get information about your local housing market—and you can do so in your pajamas and bunny slippers. Use sites like Trulia.com to find homes, check a particular home’s price history, and compare it to recent sales in the area. Zillow gives you a computer-generated estimate, called a “Zestimate,” of a home’s value.

7. Don’t assume all sellers are desperate. Some buyers lose out on homes they want to buy because they think that a buyer’s market means the buyer calls all the shots. They make an insultingly low-ball offer and are surprised when the seller turns them down. As a buyer, you’re in a good negotiating position, sure. But a seller isn’t obliged to sell his home at any price. There are other pressures on the seller, like having to pay off his current mortgage. When you make an offer, be reasonable.

8. Consider short sales and REOs. In a short sale, the current mortgage-holder agrees to a sale price that’s less than the seller owes on the home. An REO is a property that’s gone through foreclosure and is now owned by the lender.

You can find bargains among short sales and REOs, but you need to look at these properties in context. Are prices still falling, meaning the home will continue to lose value? Is the house in acceptable condition? Many short sales and REOs are sold “as is,” which means the seller won’t help pay for repairs. If you’re looking at short sales and REOs, be sure to work with a buyer’s agent who’s familiar with the ins and outs of the distressed housing market.

9. Negotiate for the best price. In a buyer’s market, some sellers try to get buyers’ attention by throwing a new flat-screen TV or a cruise into the deal as an enticement. Instead of going for a $1,000 gimmick, ask the seller for $1,000 off the price. You’ll save money in the long run by reducing the size of your mortgage and the interest you pay on it.

10. If you want something, ask for it. If you think the seller’s furniture looks better in the living room than yours would, ask the seller to include it in the sale. If you’re buying in a new development, ask the developer for free custom touches or appliance upgrades. The seller can always say no, but she might agree for the sake of the deal. In a buyer’s market, it never hurts to ask.
