Don't Be Pushed Into Any House
Your agent should show you everything available that meets your requirements. Don't make a decision on a house until you feel that you've seen enough to pick the best one.
Go to the Multiple Listing computer with your agent to make sure that you are getting a COMPLETE list. In the late 1980's, homes were selling quickly, usually a few days after listing. In that kind of market, agents advised their clients to make an offer ON THE SPOT if they liked the house. That was good advice at the time.
Today there isn't always this urgency, unless a home is drastically under priced, and you'll know if it is. Don't forget to check into the SCHOOL DISTRICTS of the area you're considering. Information is available on every school; such as class sizes, % of students that go on to college, SAT scores, etc. You can get this information from your agent or directly from the school.
Stop Calling Ads!
A word of caution - agents create ads solely to make the phone ring! Many of the homes have some drawback that's not mentioned in the ad, such as traffic noise, power lines, or litigation in the community. What's not mentioned in the ad is usually more important than what is. For this reason, I want you to be very careful when reading ads. Remember that the person writing the ad is representing the seller and not you!
The most important thing you can do is have someone on your side looking out for your best interests. Your own agent will critique the property with an eye towards how well it meets your needs and will point out any drawbacks you should know about. So whether you decide to work with me or not, pick an agent you feel comfortable with and enlist the services of that agent as a buyer's broker. Then you become a client with all the rights, benefits, and privileges created by this agency relationship, and you're no longer just a shopper.
Did you know that many homes are sold WITHOUT A SIGN ever going up or an AD EVER BEING PUT IN THE PAPER? These "great deals" go to those people who are committed to working with one agent. When an agent hears of a great buy, who do you think she's going to call? Her client, who she has a legal obligation to work hard for, or someone who just called on the phone and said "keep your eyes open"? So to get the best buy on a property, I always recommend that you hire your own agent and stick with her.
