This is a very valid question. Obviously none of us have a crystal ball but for what it's worth, here is my 2 cents.
It is very unfortunate what happened. Many people lost their homes in this tragedy. With that being said, I think there is an amazing opportunity to still invest and help these individuals in the process. By purchasing SFHs and renting them out to people who have lost their homes and/or workers that have traveled here from out of state. One thing to look into would also be renting out by the room in certain areas that allow it.
In regards to the market, things are progressing much faster than originally anticipated. There is no doubt that Fort Myers Beach will take a while to recover but here is what I am seeing in the area:
1. Sanibel bridge is already open and has been for a while now. This was orginally not projected to be open until late October at the earliest
2. Pine Island has a bridge already built while the other original one is being fixed
3. Downtown Fort Myers is seeing significant improvements. Some of the local restaurants and shops on 1st street are already open.
Although this tragedy happened, there is plenty of opportunity to still invest and help people at the same time. My personal opinion is that we will see the vacation rental market come back in 4 to 6 months. Let me know if you have any questions about what is going on down here. I would love to answer any questions or concerns you may have
