Its an island sticking out in the SF bay..

Long-time reader, first time investor from Rhode Island!

I need the real story on vacation rentals on The Big Island, HI...specifically the Kona area. 

For instance, one property seems to have an extra bathroom that is not listed in the county records.I plan to make some modifications, including removing a closet wall to expand a bathroom and taking out a kitchen island that contains electrical outlets and a switch.

My specialty is working with investors and business owners in locating island based cash flowing rentals and or non rental second homes. 

It is on the boarder next tourist areas and the island.

I have a lot in East Rockaway, corner that I am helping the owner find a buyer...Trying to get more info on like zoning and how much you can build, Property shark has been useful in NYC but pretty useless in Long Island, can not even find basic info there, is there another website or resource I can use for more detailed property info?

Where we go down is a side branch which has shallow water, next an island and then the actual river.

They also suspect the tenant has been looking for anything to complain about because she simply does not want to pay rent ever.Long story as it already is, just one more thing:  Tenant threatens to call the home inspector on me because, she said, my apartment is uninhabitable, unsanitary, and unhealthy -- and may even take me to court. 

Interestingly, I live in my community (Marco Island) with my short term rentals and have for years.
