Hello! The first thing you should do is talk to a mortgage broker or your bank. Tell them that you are looking into buying a home and you would like to get your pre-approval. In order to make an offer on a house you will need to be pre-approved for the right amount. My mortgage broker was very helpful in my search for a new home. He told me exactly what I would need to submit to him. This required a lot of faxing, emailing, and paper work but it is all documents that you should have. Identification, proof of employment, etc. If you have looked around and have seen duplexes for 65,000 and under, then I say go for it. If you are asking if this is realistic with your type of income, then yes, it is. I don't know where you live so I'm not sure what the market is like there.
