The stories of foreclosure and loss in today's mortgage crisis are painful. If you are in the market, here are five things you should do.

1. Begin with a good understanding of your finances. Examine your budget and income and determine how much you can pay as a down payment and afford each month (mortgage plus bills). Remember to factor in a cushion for unexpected costs such as unemployment.

2. Understand the lending process. Take time to learn about credit, mortgage terms, interest rates and points. Keep in mind that when you assume a mortgage you may be buying your dream home, but are also taking on a significant debt.

3. Get pre-approved. Once you have a handle on your finances and the lending process, get pre-approved for a mortgage. This gives you defined parameters for your home search and makes you a more appealing prospect to sellers.

4. Search out a reputable lender. Ask for recommendations from your real estate professional and from friends and family. Research the lenders you are considering before making a selection. Of course you should shop around for the best rates, but remember there are other important factors at play.

5. Listen to your heart and look ahead. If something seems too good to be true, it probably is. Also, take the time to analyze the fine print and make sure the mortgage terms are still manageable five, ten, and twenty years from now.
