Understand the process.
Buying real estate is a complex matter and can be especially confusing for the first-time homebuyer. Do yourself a favor and learn as much about the process as you can before you begin. There are plenty of resources on the Internet, and most real estate offices will have pamphlets to explain things in plain language. You may also be able to research the real estate process by attending community-sponsored classes, or you can take a look at books like Home Buying For Dummies by Eric Tyson and Ray Brown, (IDG Books Worldwide, Inc.)
