Should I be suspcious?

[Dante Williams]

I made a verbal offer on a property a few days ago. The seller agreed to the price, but wants to close using a quit claim deed. I asked for a warranty deed, but he says that quit claim will save on closing costs. which is true but should I be suspcious of this guy? I know that there is a little over 3k in taxes owed and the property is in his "brothers" name, but do you all think that there is something else going on?
