Renting to buyers before short sale approves?

[Kimberly Gordon]

I listed my home for sale at reduced price in hopes of EMC mortgage co. accepting the reduced price. Now the interested buyer wants to know if- once they put the contract down- we would rent to them until the short sale is hopefully approved. Good/ bad idea?? I just don't want to be stuck with renters if short sale is denied...
Any advice is appreciated.
