@Bill Flannagan I use On-Site for my leases and they've been pretty good, check them out.

Does anyone know where on the site the state-specific rental contracts are located?

As far as finding out who the city planner is to discuss the legal aspects of that is it just as easy as googling city planner of city "x" or is their a specific site you would recommend?

Purchased site unseen although there was a video of the property that showed the home in detail.  

You probably need to slow down and breathe for a minute contrary to what most others on the site might tell you. 

I have found properties on Hawaii Life that were not on the other sites. 

I can't imagine that there are landlords on this site who don't do it. 

Hi my name is Cameron and I have been a BP member for a few years, I have only recently become active through the site.

What is your advice on the best site to purchase them?

the market will determine how much your information is worth when you package it.write a book, do a podcast, start a blog. information sales however is a low cost to entry, most people give out information for free (check out a site called www.biggerpockets.com to confirm).
