Hi @Andrei Zharov,
Since you're planning on utilizing the property for personal use, I would imagine the beach component and all other criteria you listed are more so personal than wanting to optimize for an STR, which is totally okay as many of the things you listed are completely in line with the optimization strategy. One thing that I would note though is that Cape Coral and a large majority of Fort Myers do not have easy access to beaches right now, so the next closest beach is already going to be in Bonita Springs. It may make more sense to start there with your search and expand if needed
Hurricane rehabbed homes are completely safe to purchase, assuming you know what to look for. A good inspector shouldn't have any issue pointing out cut corners, or major issues that weren't addressed. If you were to purchase a home that needed rehab, some of the difficulties you're very likely to encounter are significantly lower inventory for these damaged homes, material shortages and delays due to high demand, and surge pricing for contractors also due to demand, assuming you're even able to find a competent one for a good price. All of this considered, I would advise against this route unless you had extensive experience in this space
Water entry into a house is something that could actually be not so much of a big deal, to near total destruction. Visually, the differences may not even be very apparent, so cost to rehab homes like this can vary drastically, and it's very difficult to make any blanket assumptions on remediation costs. Some of the variables that come into play include structural rigidity, plumbing and electrical integrity, current mold damage, etc. Again, all of these variables may or may not come into play depending on the height of the water entry. Several inches in this case could mean thousands of dollars more on remediation and rehab
