There certainly are off market multifamily deals that are profitable, but those can take months of repeated efforts to secure. 

I raised one of their rents $100 in March which put them at what I thought market rent was for their unit ($1850 for large 2/2 with own yard).The way I look at it is if I spend $2K on tenant turnover it takes 10 months to be "even" financially but there was also the small amount of effort to fill the vacancy. 

For that reason, I'm trying to focus my research efforts more on areas that have skilled laborers and hospitals.

Accepting a tenant backed by a Section 8 voucher, and agreeing to spend time/effort above & beyond what would be required by any conventional market tenant are 2 mutually exclusive things.I'd be happy to accept a Section 8 tenant, so long as the following was understood in advance:1) The Housing Authority (not me) must fill out all paperwork regarding my home, and send to me for easy electronic signature.2) I must be compensated for the time my home is removed from the market, while awaiting the Federal Inspection - assuming I find a qualified conventional tenant willing to rent during the inspection waiting-period (a per diem for potential rent-loss). 3) The inspection must be scheduled with consideration for my convenience, and I must be compensated for the time taken to travel to the property and meet with the Inspector.In other words, my total "charge" as a PM to process all paperwork & handle the Section 8 scheduling/inspection would be a reasonable $100-$150.

As soon as you are able is to attend local REI clubs that are genuinely for learning and are not just a front for sales people selling something you do not need.

For me, the point @Scott Trench made was so simple, yet easily overlooked on my efforts. 

Everything works, you just need to put in the time and effort to get it done.

(There is a recent surge in hands-on management companies and conscientious landlords who actually want nice properties entering the market.)Why it's different this time is only partially attributable to neighborhood improvement efforts.  

I have worked hard to set up systems and team members to allow me to manage my properties with little effort and it has worked out great.  

You don't add lending restrictions to ease efforts generally required of a lender, restrictions and covenants should have a risk management basis or element, not necessarily a profit motive, interest is to cover profits over these usual and customary risks, not high rates and then more restrictions.
