Unfortulatelly it usually doesn't work this way. I have had some of my REO properties that have renters in them when I take the asset over who want to do the same thing and it has never worked out. If you can find an investor on your own and then they buy the home at the county court house steps and then have them rent it to you with an option to purchase back it could happen but very very unlikely. I think you might want to consult with a Realtor and an Attorney. A short sale could be an option for you. If you keep your credit in tact you should be able to buy in several years but for now renting might be your best bet. Best of luck.
