DO  
Take the time to analyze what you feel are the most important features of a home; and then decide not to settle for less. For example, if you currently struggle with having a one-car garage, be sure you tell your agent you want a two-car garage in your new home.

DON'T
Purchase a home that is considerably more expensive than the surrounding homes. The lower priced homes will likely lower your own home's value.

DO
Investigate the local school system. Whether you have school aged children or not, school systems do have a dramatic effect on the value of residential real estate.

DON'T
Be too quick to purchase a home on a busy street or one that adjoins any non-residential structures. The reason that you may be able to purchase one of these homes at a lower price is the same reason that a subsequent buyer will expect a price concession from you.

DO
Study the floor plan to be sure that it has the number of bedrooms and bathrooms that are normally desired in that particular price range. For example, subsequent buyers will likely expect a two-story home to have at least a half-bath downstairs.

DON'T
Buy a home because of the decor alone. Make sure the home also has the more permanent features that you need. You don't want the carpet and wallpaper to distract you from noticing that 
a home has plumbing problems.  

DO
Investigate the ongoing costs of owning this particular home. 
This includes factors such as the taxes, utilities, and maintenance costs. You may be able to afford to buy it, but unable to maintain it.

DO
Seek the help of a competent Realtor who can guide you through all the phases of the home buying process.
