Producing apartments or food or water remains a competitive industry. If the people purchasing them gain more income, I could in theory see the existing suppliers deciding "we will just increase prices," but a new supplier could enter the market using the old players' old model and steal all their market share. (If the basic income is done just by giving everyone a check, then I could see costs rising, because people refuse to work for current wages. The more sensible way to implement a BI is with a wage subsidy so people still work.)
