In commercial an offer is not typically used. 

A typical sand and refinish in my market is going to run 600-1500.

It's part of the Fannie / Freddie regulations that these banks adhere to.

If no, I would recommend using your local Board approved contract from the local association of realtors...these are typically legalese, but offer the most protection.

Find out what they typically look for in a property and go hunting!

If that property is fairly rural and is not as desirable as a typical place "for sale" location, it might be better to rent it and plan on holding on to it for a while.

Typically you can't rent out a single apartment unit because of sublease clauses in your lease.
