RAAS and 'Geezer' Safety

After years as an NL member (of very infrequent responses to other people's posts and never, until now, a post of my very own), I'm taking the plunge. I retired early and have just about finished my last big home renovation. I spent time in Nicaragua last year and am heading down again in late April with my younger son, Hawk. He has been communicating with some people about land that might be for sale on the east coast. We're flying to Big Corn, and although we haven't heard definitively yet from any of the people he's been in touch with, we hope to hook up with at least one of them to look at properties on the mainland. I plan, initially, to build for myself and family - because it'll be a couple of years before either of my sons and their families will be able to join me full time for expanding the beginning efforts into a small tourist facility. So, my question is a general one about safety issues facing an older woman who'll be settling in and building while alone. The general outline of what I intend is to have constructed both personal and caretaker quarters, preferably with solar/wind power and cisterns for water; and because I realize that not much of what we hope to look at has any road access, I'll be making provisions for the docking of at least a panga. I'm not too concerned with the problems that will be involved in construction(s) in a remote area, but I would appreciate some input from anyone who might be able to speak to the specific hazards I might face doing it by myself.
