To be honest with you, would you put homeless people on your property? Look at what they are doing to the beauty of our Island.  Take a drive on Nimitz Hwy., it's disgusting.  That is why we need Bill 1850 to pass so that the state can put this money in a Housing Trust Fund and get these people off the streets and parks and into some kind of living complex and start teaching them a trade so they can work and get on their feet.  
Don't keep accusing vacation rentals for the shortage of housing, it's an old story.  The true fact is we have lots of investors buying up all the properties and turning them around and making big profits.  The state and city should have stopped this a long time ago and started taxing speculators that are doing this.  Higher taxes are needed for owners that are not occupying the property.
One more thing, the State should be talking to the Mayor and City Council on permitting owner occupied vacation rentals, thats the only way this is going to be fixed.
