Vacation rental on semi-private island?

[David Miller]

My wife and I are looking at a property on an island this weekend. The property is not listed but likely will by the end of the month. We do not know much about it but the island itself is roughly 3-5 acres. It has 3 independently owned cabins(called camps in Maine). The one we are looking at has the majority of the land associated with it. I know it has electricity, running water(well), indoor plumbing...everything your home would. 

We are looking at this primarily as a vacation home for ourselves but we’re wondering if it would be feasible to rent it out from time to time, maybe one week per month in the summer. This would allow us to potentially spend a little more. The reason we aren’t sure about that being possible is that the only access to it is by boat. Meaning anyone staying there has to have their own boat, rent a boat...just to get to it. It wouldn’t be possible for us to ferry groups back and forth. I’m sure convenience is very important for vacation rentals but wasn’t sure if the lure of being on a fairly private island would overcome some of the challenges. 

We are just looking for some insight as we prepare to look at it. It may be completely wrong for us but figured those with more experience may be able to help.
