I am trying to buy some vaccant properties from a investment company in Florida. These properties are tax deed properites they obtained from auctions. They offering me quiet claim deed in lieu of warranty deed. I am little confused to buy these property. Also I want to know, these tax deed properties can be sell or is there is any waiting time.

A warranty deed means that the seller warrants that the property has clear title. A Quit (not quiet) claim deed includes no such warranty.

You should do a title search regardless.
