I'm doing a new construction multi family development. I'm having a hard time quantifying the positives of new construction due to lack of comps. If the multi family was existing I would be at around a 10 GRM. Obviously new construction benefits from a number of things- easier rentability, zero differed maintenance, etc. Anyone want to speculate on a GRM for new construction with the understanding a non new property would be at 10 GRM? I'm going to have it appraised regardless before building, but just trying to put together preliminary valuation.
