I don't know anything about construction, but I do know that my landlord is based in cayman islands. Why do we allow tax-heaven based shell companies to buy housing in areas where we officially declared a shortage, especially when we know much of that money is either stolen, or comes from dictators, or is doing tax evasion? It can't be helping the problem
