Depends on what the "sleezeball" got paid to put the building up.
Low bid usually gets it and with the cost of building materials plus permitting, zoning issues, $300/hr electricians and HVAC companies raping you...
Not to mention what a yard of concrete now costs...
or that piece of commercial zoned property it's sitting on.
But don't think you won't get a cut, the lucky business that moves in that building will pay extra property taxes, more for utilities and provide jobs long after the Mexicans have moved on to building another building. Also the business that moves in there will have to file I-9's, so no illegals can work there. (unlike subcontractors)
