As the others note, you didn't ask a question in your earlier post. Also, your post was extremely difficult to understand.
Apparently, after some years of good credit, your credit has declined. And you want to buy that home. First, find a good Realtor and have him/her do a CMA on the property. Ask the Realtor for the names of two or three good mortgage brokers. Choose one, meet with him/her, and find out what you can qualify for. Based on that information (what you can qualify for and what the house is worth) you can decide what to do next.
