In any case,   one argument FOR holding onto smaller apartment properties in seattle is that townhouse redevelopment,  which requires the same zoning as small multifamily causes a lot of SFR and smaller apartments to be lost to redevelopment,  so this class of neighborhood scale and typically comparatively affordable housing is going to get harder to come by,   and presumably in higher demand as a result.

But many roofers don’t, and because it was done prior to closing, the seller probably chose the cheapest option.

I'm interested in potentially placing some bids on some properties in Mecklenburg County in NC but am unfamiliar with how the due diligence process works compared to a typical property purchase.
