where I have done below market is :Land with Timber.. 

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

But I also like Belize, Virgin Islands, Hawaii, Croatia, etc.  

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.

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?

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

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

The main issue is land... or lack-there-of.

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

Its an island sticking out in the SF bay..
