Until you've been pre-approved, most realtors will not feel comfortable showing you another home. There are, as someone else mentioned, hurdles to obtaining financing in your situation, and the following questions will need to be answered:
Are you planning on selling or renting your current home?
How much equity do you have in your current home?
Do you have any landlord experience?
What kind of reserves will you have in place after purchasing the foreclosure?
Having great credit is only one step in the process. If you'd like to discuss the next steps, please feel free to give me a call, or complete a FREE on-line application by clicking on "start the process" at my website.
