My area is susceptible to hurricanes and is influenced by tourism, and I'd like to get into a few different markets over the next few years. 

I'd say that having a combination could influence the asking price, as the SFDs can carry more of a margin than the complex.

Your approach to a HML or a conventional lender usually done with a purchase contract or plans and specs in hand.There can be situations where a PHA E.D might influence a lending arrangement, PHAs don't lend money. :)

I would focus on targeted Social Media groups on Facebook and Instagram influencers that can bring the right attention to your properties.  

You can read real estate folklore, like Rich Dad or How to Buy And Make A Million, but without understanding the industry you're trying to deal in and the influences that play on real estate, you're going to be lost and chances of failure go up.So, the very first book you should study is one that teaches the basics of real estate, not real estate investing or dealing or operating.

Also be aware that agent cannot influence the buyer to breach your contract.

Will definitely speak to my sphere of influence and make phone calls as soon as possible.

Consider things like if you pay AMT and if the 401k deduction has any influence on that.

If you want to prepare your business for recession or worse then read J Scott’s book, do some reading on the big 5 factors pushing us into the everything bubble; Subprime auto loans, corporate debt, stocks, student loans & real estate in order.I personally believe the best way to prepare for downturns as a real estate investor is to invest in mobile home parks & there best & brightest syndications if you don’t want to buy & run a park & to invest in silver because of the upside potential in a false economy like we live in now because of the bubble making influence of the federal reserve & endless QE & interest rate manipulation!

Not gonna lie my "criteria" is somewhat easily influenced right now.
