Hey Kristi:
Do you know that you connected to "Microsoft"? Anyway, check the
yellow pages for "property management" firms because you'll need a document
that's legal and legally binding in your state/county/city. I'd also
consider contacting a lawyer that specializes in real estate or property law.
You'll need notary services, brokerage documents, the ability to do credit
checks on prospective renters/buyers, and possibly special insurance
considerations. There are also a number of "sell it yourself" consulting
firms that will sell you "packages" that will help you through the process.
Lots of luck.
