Should have quite a number of short stay units available for rent. Perhaps can try those for a day or so? Best if can be for a longer period before committing anything. This place isn't your normal property indeed (abandoned mall, low occupancy).

Either EXSIM has really big balls or they got a damn good deal (for the land) or know something that we all don't know.
Otherwise, why would they develop not one, but two projects in this decade failed development? So sad to see the place in it's current state. So much potential, yet, not alive.
