Trevolyn made some great suggestions regarding possible financing options. One other option to look at for possible financing is the USDA Rural Development program. It is a program designed for first time homebuyers in Rural Areas.
If you have any questions I would be glad to talk with you about your options. And I bet that between the two of us could find a realtor that would be excited to work with you.
Best of luck on your home search.
Could I ask why you feel that you need to do a rent-to-own?
It is a great tool to use for individuals that may not be able to purchase otherwise, but I always want to see if my clients have other options first.
An example would be: FHA is a great loan for young first time buyers like yourself &, right now, it is possible for you to get into a home with only 3.5% down(!) which is fabulous.
I can also refer you to a great agent in your area if you contact me (@909-262-6221 or Trevolyn@century21.com )
