When the market turns, all of that plentiful rental demand may dry up.

But as far as areas go, I believe best "resale" would be in areas called "high and dry" meaning they are a  few feet above sea level.

you would be surprised you can live off of $10 of dried beans. 

But you factor that into your rental ratesOn the question about SFR, I have them in Orlando but not here on the beach, yet The reason I don't have them on the beach is because when I do Vacation rentals I have 2 criterias, 1 being can you pay mortgage, insurance and taxes with the season rentals2 being if the vacation rental market dried up or the law change could you rent long term.What I have found is on the beach especially where we are , Manasota Key the wages here support rents of about $1000 to $1200 a month Rents like that usually will not cover a long term rental mortgages on a SFRbut by going with multi family units all 3 of my building units can be rented for $1000 a month long term and I would be able to cover my Mortgage, insurance and taxes each month.In Orlando I have units that are getting $2400 a month because the higher paying jobs are there.Now I figure when I get a few more multi family units on the beach they will be able to carry SFR to be used as vacation rentals

However the first home of any kind I ever knew was constructed of bushes, dried tree branches, card board boxes, and everything tied together with shipping string, had dirt floors, no plumbing, no electricity, and not water.

As far as other materials and tools dry wall putty (touch up paint) caulk Roofing MASTIC <--- this is a must for roof maintaining Also bring garbage bags and a long hose if you dont have one.

Obviously, it's never that cut and dry, but in my experience, if I can't find a problem to help solve, then I provide no value and can't find a deal.

Money supply has grown exponentially, weak businesses have been formed and failed, the consumer is leveraged up to their eyeballs, regulation is poor, and savings have dried up.

The cost of electricity is more than gas.There is also typically a value adjustment for electric baseboard vs gas forced air- less of concern if you plan to hold for long term.You might find that when you start pricing the install, with an electrician, potentially more circuits, dry wall repair, etc that the furnace isn't so bad after all.

Set some fans and dry everything out completely before you re-dry wall it.
