1st phase ex-buyer or 2nd-phase ex-buyer?

You call the price of a 250k high density apartment from a small time developer built on a mining site with so so location "cheap"? Everything else is CHEAP but definately not the price. The end price the buyers need to pay could be more than 250k eventually.
