Any "business" that does not have a web presence in 2015 seems a little sketchy.Again I know nothing about them, so take my opinions with a grain of salt.Be careful and let us know what you find out.

Don't know if there's a crawlspace but you could look into a conditioned crawl space or vapor barrier as well - we have a lot of crawls here and a good vapor barrier has helped to dry out a lot of the subfloor and reduce humidity throughout the whole house.  

The link from youtube is just a link I found on the web to share with you guys about how the condo looks.

I am not very good at the web site stuff and don't use facebook,  so I could not tell how to look at any of your links..

Find it here or search the web for it under my big why..It helped me find what I needed to get it all wrapped up..Good luck to you..

I have about 15 years of experience in web programming and I'm sure I can steer you where you need to go.

@Mel Wyatt Does RMS have a web site or other contact info?

The IRS has pretty good reference material on their web site.  

We do a lot of work in flood zones and from what I've heard regarding "stilts"(we call them pilings) is you're looking at 20-30k extra over a traditional slab with a crawl space....Most of our footings are within a couple feet of sea level so we've never needed pilings but if you're indeed that deep you defintiely can't pour a footing on top of muck.....The other concern is flood insurance - the lower your first floor elevation the higher the flood insurance - I'd imagine if your first floor is under 10' the insurance would be astronomical.....your best bet is to talk to an engineer, get a survey, and go from there.
