You might find neighbors are a lot more receptive if they feel like they have a sense of control or influence (emphasis on "feel"). 

I can’t put enough emphasis on this.

Also I really appreciate the advice and since you gave so much emphasis on the book will look into getting a hard copy!

@Michael Woodruff  As @Nick C. said, that is exactly the kind of thing that requires a real estate license in Massachusetts.Here are the most relevant parts of the MA law from the link I provided above - the emphasis is mine:''Real estate broker'', hereinafter referred to as broker, any person who for another person and for a fee, commission or other valuable consideration, or with the intention or in the expectation or upon the promise of receiving or collecting a fee, commission or other valuable consideration, does any of the following: sells, exchanges, purchases, rents or leases, or negotiates, or offers, attempts or agrees to negotiate the sale, exchange, purchase, rental or leasing of any real estate, or lists or offers, attempts or agrees to list any real estate, or buys or offers to buy, sells or offers to sell or otherwise deals in options on real estate, or advertises or holds himself out as engaged in the business of selling, exchanging, purchasing, renting or leasing real estate, or assists or directs in the procuring of prospects or the negotiation or completion of any agreement or transaction which results or is intended to result in the sale, exchange, purchase, leasing or renting of any real estate.As I said before, there is not a millimeter's worth of wiggle room in there.Right now, I'm working with a young couple who is selling their home here in W.

[Emphasis added]I'm unaware of any place in the internal revenue code or regs that states rents received in cash are exempt from federal income tax.Textbook fraud has two elements: (1) financial gain and (2) scienter aka intent to deceive. 

Your emphasis on diversity has always been used in unfair housing and discriminatory practices like red-lining.

Looking into house hacking a Duplex but noticed some only have electric metered separate, leaving the owner to pay gas and water.How much of an emphasis should I place on the home having completely separate meters vs only electric?

During your lease agreement signing with tenants, be sure to have a dedicated section in the lease agreement that spell out clearly how the rent to be collected and emphasis on Late Fee, rent is due on the 1st of the month, 10% late fee apply on the 2nd ( no grace period), 5th day send out pay or quit notice, 9th day file eviction, you get the idea and you can revise it accordingly..

The importance has always been in making sound deliberate decisions each investor can tolerate based on their needs/tolerance for fluctuations.Perhaps much of the lingering fear is due to a recency bias that places more emphasis on the last recession and how it was associated with real estate?
