Yeah, I ran into this years ago after hurricane Florence. My only thought is to seek out properties with minimal damage that can quickly settle the claim. A good number of people want to be done with vacation homes in these areas after an event like this, and you might find them amicable to a deal.
I spent time in the Carolinas after that hurricane doing restoration work. The more affluent owners settled claims quickly and secured contractors to do the work even if they ended up coming out of pocket. A lot of times it was an excuse to upgrade. It gets harder the further away you get from the event.
At the beginning the insurance companies are eager to look good and stroke checks, but the longer time goes on, the less willing they are to please the owner. Thats my experience anyway.
Connect yourself to some of the adjusters in the area, and they can be really helpful since they will have first hand knowledge and experience with which insurers are being cooperative and which ones to steer clear of. They probably will also know which owners would be interested in making a deal.
Im not the most experienced in this field, but there's a lot going on. I'd say your best bet though is talking with the adjusters. They will be all hanging out with the other trades getting a beer at midnight and their first meal of the day. If there is any restaurant still upright. DM if you want to talk more.
