I don't think you'll have a problem finding properties in your price range - there are certainly nice townhomes, and even single familty homes to be had in the 200s.
I must say that I'm a little less optimistic than some of my colleagues, who are quick to assure you that seller-financing is plentiful. Homeowners who are selling in order to purchase a new property don't generally have the financial wherewithal to have money tied up in two homes at once, so you're primarily looking at investor sellers, but even those entities are generally looking to free up -the money from one sale, so they can reinvest in new assets.-
If you're hoping for owner-financing because your current credit status won't qualify you for traditional mortgage products, I would recommend that you find a knowledgeable mortgage professional to work with, rather than seek out the far less common purchase money mortgages.
Sorry to be a Debbie Downer, but I think some of my colleagues migh be assuring you that something quite rare is readily available in this market, and that has not been my experience, at all.
I hope this helped!
