In todays real estate market it is often possible to get a owner contract, or possibly a 2nd mortgage, You are then looking for a home that as an owner that is not not in dire straits and perhaps has already moved on and has two house payments. Depending on the sellers financial needs some can be fairly flexible. You should expect a credit ck and to provide proof of employment to show that you can be successful at the purchase.

Any licensed agent can find them through the MLS system.

I post my rentals on http://www.craigslist.com or drive areas of interest from my clients. What are you looking for and where?
