Buying a home is often the largest personal finance transaction a person makes in his or her life. So it's critical that you make the right preparations and do the proper research. Regardless of unique situations and special circumstances, there are four things you must do before buying a home.



1. Determine your budget. Use an online mortgage calculator to get an idea of how much you can afford to pay each month, and what that equates to in terms of a home price. This will give you a budget to work from, which will help you weed out the homes that are beyond your comfort zone.

2. Obtain your credit report. Get a copy of your credit report and review it for errors. You can get copies from all three credit bureaus at once by visiting www.AnnualCreditReport.com. Mortgage lenders will review your credit with a fine-toothed comb, so you should do the same ... before they review it.

3. Validate the asking price. It's called an "asking price" for a good reason. No asking price is set in stone, and everything in real estate negotiable. So don't accept an asking price as being reasonable until you validate it through careful research. Compare the home / price to recent sales in the area. Your real estate agent can provide a comparative market analysis (CMA) to help you with this step.

4. Avoid new lines of credit. Try to keep your financial situation as "stable" and favorable as possible. It's a good idea to pay down some debt (see item #4 above) and to save up some cash. But the worst thing you can do is take out a new loan / line of credit. At best, this could make the qualification process take longer. At worst, it could tip the debt scales into the "greater than 20%" zone, which will make it harder to get a loan.
