"Just a little damage" Walks flat, needs roof and cosmetics. 

Another option is to hire independent inspectors or even handymen whom you can pay a flat fee for every time they inspect your house.

Can I demolish the roof and build above it to raise the living space above the base flood elevation.

I believe so, Jessica - this is where 3rd party processor based digital platforms fall flat.

Some have higher flat fees.

The only way that makes sense is if they charge a flat monthly fee but nothing for finding a renter. 

I would caution on comparing these returns to the S&P 500.Real estate has been pretty much flat the last 2-3 years while the S&P has been on a great run.It's human nature to sell the lows and buy the tops.

This of course depends on your starting bank roll - but if its like mine (under 100k) - Im trying to put as little as possible into it on top of initial equity and fees.this will likely chew a big hole in your ROI  (now if you are looking to improve value with a cash out refi or a great prospect comes along that needs combo new plumbing, roof, windows, foundation repair, etc - well just make sure you know what youre getting into and/or have a good contractor and finger on the pulse of the market when estimating the ARV YOURSELF - couple missed items and you risk having a bad first investment and not doing it again).    7) dont be scared be ambitious ( i should heed my own advice sometimes) 8) define numbers goals within your target areas.  

What is your roof goes, a heating unit.... you're credit card debt could build up quick as a result of this putting yourself in a bad situation.
