Mary, there are a few things you should do before you can purchase a home.

1. Find an agent to work with, that will represent you well in this market. Make sure they are experienced.
2. Get pre-approved by a lender if you haven't already done so.
3. Get current bank statements ready, showing you have the funds necessary to buy a home and cover closing costs.
4. Get a copy of your FICO scores to submit with your offer.
5. Have your agent explain the process to you, and become familiar with the current market conditions.

If you still need an agent, there are plenty of us on here that service the Anaheim area, and you can check out our profiles to see if they are knowledgeable as well.

Best of luck,
Jeremy
