And the reasons is not so much the tenants, but the paperwork hassles.As a landlord who accepts HUD vouchers (Section 8), you still have the right to set your own tenant criteria.  

That being said ( and I will be interested to hear from some of the larger syndication groups ), I have found larger check writers (family offices hedge funds pref equity groups etc) often want some element of control and higher returns for their investment and so perhaps that is why larger operators accept smaller checks too. 

Recommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

They may have tightened up their acceptance if they have seen an uptick in evictions.

Question is if we have a conversation with each tenant about what they feel is a fair rent and one says $1375 and the other says $1400, and $1400 is our target - should we accept separate rent amounts?

I would not have accepted the offer if I had known they would not cover it.

In this particular property the GFCIs were on the circuit breakers which is acceptable by code.

Also, are there any social media websites with groups that I could network with that highlight investors & wholesalers?
