Having said all of the above, I have not seen hardly any reductions in typical pricing for the Multifamily units. 

How about I'm an Equity Reduction Engineer?

If it is for buy and hold, since the units are presently occupied, it all depends on when the leases expire, I would not worry too much about the repair cost now, only to ask for a reduction in the asking price since you will have to do the work later. 

I recieved a statement in the mail for notice of assessment stating a reduction of $369.53.

There are still many gray areas for which the Treasury and IRS have not made clear regarding documenting and guaranteeing that the actual deferrals, cost basis reductions and permanent exclusions will be honored in any given business and property combination.This alone has tempered my interest in Opportunity Zones.

I will do it but with  a normal new tenant process,  sometimes is better give some rent reduction rather spend a lot of money on repairs,  evictions later 

Yes there will be some lay-offs and force reduction but it cannot be too significant as so much money has been spent developing this installation and it is still ongoing.

If you have polybutylene piping it could cost a lot more to re pipe the home and that should help you to negotiate a further reduction in price.

Several of the obviously-flipped and listed properties for sale have also had recent price reductions. 

This study by the Federal Reserve Bank of Cleveland comparing government housing to vouchers was pretty definitive at least in that regards: “…closing large public housing developments and dispersing former residents throughout a wider portion of the city was associated with net reductions in violent crime, at the city level.”https://www.clevelandfed.org/p...
