Which loan do I best qualify for?

I own a 1979 Mobile Home on my own land, valued at $60,000 in 2009. I owe nothing. My car is paid for, I have no credit cards. I am debt free. I work part time and gross $640/mth. I also make about $500/month on the side with Ebay and Flea Markets (no proof). I am 49, single, no kids. I never filed bankruptcy. I would like to purchase a Condo for $45,000 with $25,000 down. HOA fees are approx. $250/mth. I will sell my mobile home when the value goes back up to $80,000 like it was in 2007 or I will take my losses and sell by 2011, whichever comes first. I checked my credit and I have 2 unpaid hospital bills for approx. $1000, otherwise my credit is good (I don't know the score). My question is, considering my income and everything else, do I qualify for a loan for $20,000 for the condo (which I will pay off when I sell my mobile)? If so, what type of loan would be best for me? I plan to live in the mobile and rent the condo until I sell the mobile. Thanks.
