Mainly focusing on class B and A- multifamily. 

Almost all deals are syndications using Reg D 506(b) and an occasional (c). 

Joining multiple multi-family syndication groups has enabled us to scale from 0 to 2,600 doors across Class B and C deals as co-Sponsors.   

Then drive out to those cities and get to know the neighborhoods and which are Class A, B and C.  

I'm a tenured professor in the music department at Michigan Tech University and lead my own bands and play with some folks it's possible you've heard of. 

Baltimore Market Snapshot:Multifamily: Baltimore’s got a decent multifamily scene—median rents hover around $1,500-$1,800 for 2-3 unit properties, with Class B and C buildings in areas like East Baltimore or Hampden offering cash flow potential.

I would guess cherry picking is going on and then B and C's are sold off with what is left over.

Make sure the Belly band is kept caulked to avoid leaks.

Purchase a large property with a fairly large SFR (at least 2400') in a higher class area (class B+ and above) and place a 1200' ADU.  

@Spencer CuelloI would google 506 B and syndication companies.
