selling a tax deed or best way to sell property

[Joshua D.]

So i recently went to a free and clear tax sale and won a property. Now im waiting for the tax deed to come in. Is it okay to list the property for sale before the deed is in? I have people interested and willing to pay cash. Also what is best step in selling the property should i do a quite tittle search? The owners are deceased but the son is still alive and lives right across the street. I heard i could avoid doing the title search and have him sign off on it or however the process works. I would appreciate any help. Thanks Josh
