The valuation of the property is done a little different as Apartment buildings are valued much like commercial properties (in the 5+ unit range) where the value is determined by the income the building is (currently) producing. 

The place is in my price range.

These homes range from 3000sf to 3600sf and each have finished walkout daylight basements and these sold homes have recently and consistently sold at $220/sf. 

However, after talking to the bank, the only way this could occur is through refinancing with closing costs ranging from $4500-$7000.

I have a recently fully renovated SFH in S MPLS that I'm currently renting out that I will be selling this fall/next spring in the $260-$270 range but will probably sign a lease extension until 6/1/21 as no non renewals aren't currently allowed. 

Those cities are namely - Holyoke, Springfield, Chicopee - and you can get properties in the price of $50-60/unit count with rents in the $900-1200 range for 2/3 beds.

Given the incredible range of outcomes from 3 months of turbulence, demand is not the driving factor. 

I am looking for deals that range from 20 units up to 150.

From your post it looks like you are under the 80k range, which either means you are in the south side looking at single family homes or in the suburbs looking at condos. 

Simply put, the margins are small for the builders which means the current homes in that lower price range are going extremely fast.
