Quote from Scataphagos:
Don't the builders have to finish the development or building if at all possible? Otherwise, a half-finished project is worth virtually nothing, and all the money they've put into it so far would be wasted.
To complete on the loan, yes, they need to finish the project even if it has little chance of selling/leasing. There are still, quite a few unfinished projects, contrary to what Clubber Lang claims. Nothing like Miami or Vegas, as they are more scattered.
