Additionally, vacation rentals is a very sensitive issue here in Honolulu these days.

Try not to be so sensitive ;) Also my “tenant” moved out without having to take an legal action because even they realized they were wrong.

I have a very sensitive nose and hate the smell of smoke.

As Charles sort of suggested, there's probably some sort of economics-based differential equations that could be used to model return vs risk vs time in various investment activities.While it probably wouldn't be useful in real life (not sure you could tune the inputs well-enough to be meaningful), you could probably play around with various inputs to get a feeling for their sensitivities to one another.If I were smarter, I'd probably be able to apply some of the utility modeling work I used to do as a poker player to real estate investing...Which actually reminds me that I've been meaning to start a really geek thread on a related subject...a bit off the topic (or maybe not), but if you've studied card counting in blackjack or were ever a geek poker player, you may be familiar with the Kelly Criterion...I've recently started thinking about whether there is a way to apply the concept to portfolio real estate investing:http://en.wikipedia.org/wiki/Kelly_criterion

I know you're not seriously looking at this deal, so of course you didn't waste your time collecting all the data - I wouldn't have either - but it's all that data that will make or break a deal like this, especially for a prop that will likely have cyclical income -  a vacation home is very sensitive to economic conditions, which makes them inherently more risky.

It's a customized Schlage lock that lets you give time-sensitive codes.

I have been wrestling with that, the current operators in the area are focused on the outside storage which is at a lower price point, I am considering the fact that some people would like to store items that may be sensitive to changes in temperature. 

I probably have the most sensitive BS Meter on BP, or in the real estate education arena, it just comes from experience, investigators assume there is wrong doing until proven otherwise, with gurus, none have passed scrutiny yet.
