The most important tip for transitioning from renting to buying is to Be Prepared.
Do two things first:
1. Talk with a good lender about the loan process and what you can afford to buy. You might be surprised--either happily or unhappily. If your credit score or income aren't as good as they should be to qualify for the loan amount you need to purchase your dream home, you might be looking at a longer time saving and paying off bills than you thought. There are good lenders who can actually have your loan fully underwritten and approved before you identify the home you want to purchase. This makes you look like a much stronger buyer to the seller who may be considering several offers as well as yours. Because, of course, if you love that home, you can bet others will, too.
