There are also some properties offered for $1.00 for public interests. Either to take the house away they sell it for $1.00 and then the developer has the land or in the case of a government entity selling it for $1.00 it might be for the greater good of the neighborhood/community to redevelop the property for a higher and better use.
Either way you'd have sales tax (tax stamps), recording fees, attorney fees, inspection/appraisal/title fees and in the case of selling building only then transportation & utility costs (installation, removal, upgrading, relocating etc.). All the costs would be property specific and the entitiy selling the property would disclose approximate costs, you'd be wise to consult an experienced real estate attorney to review all documents & contracts to understands your rights & responsibilites.
Hope that helps,
