to add onto what @James DeRoest said, in addition to ongoing sealing you have to do to maintain it (which you probably don't want to entrust a tenant with), granite is porous (like wood or skin), so if a tenant spills wine, or oil, or grease, or meat sauce, or fish guts, or chicken innards, or other liquids that can stain, those liquids seep into the pores and may not come out if not properly attended to, leading to discoloration.For B class tenants, the ROI is not with it.
