Government agencies are limited to what they can do.
I presume this entitles property owners to some sort of tax exemption or other incentives for building in a depressed area.
The top three options that cities can use would be: 1) Reduced or no property taxes for up to 10-years. (Not seeing it here) 2) Reduced or no city fees to build. Credits against the SDCs (System and Development Credit's) 3) State or Federal housing credits for "low-income" housing against the investors tax bill.
The benefit in redeveloping existing structures has to do with credits against traffic counts, and water/sewer fees for the most part. However, paying for $4M for a 120-units ($33K per/unit/Land) is going to be a very high bar when you also add in demo and site costs. To say nothing of the holding costs on $4M for two years.
