I let them out of their lease, but the situation was not resolved until I tracked down the out-of-state owner of the property (actual property manager would not do anything), and let him know I was having huge problems with his tenants, numerous police reports filed, that his property manager was doing nothing, and something needed to be done or I'd hold him liable.  

His worries:-if I build on the land during the lease, I could end up losing the property in foreclosure if the owner defaults-I put too much money down as a option fee, he feels I'm gambling -there isn't any wording in the contract on who will take care of structural problems i.e.: roof leaks/replacing he basically looked at me like I was an idiot, until I told me-I don't plan on building on the property before I own it, the seller is giving me the paper work to talk to the city and see if the building was viable.

As an example: This beautiful Church preservation Project , or this cool old time Theater conservation & reconstruction Project  as well as numerous beautiful architectural Brownstone & Limestone low-rise 2 & 3 Family Homes that are being renovated...

an old saying when you go to Vegas is "don't gamble scared", which essentially means make sure you have enough money to bet big when the odds are in your favor….i would modify that quote to fit RE to "don't invest in RE scared"…have the nest egg at the right size before you jump.  

Google looks at numerous data points for each click, including the IP address, the time of the click, any duplicate clicks, and various other click patterns.

I do not think this is a gamble as you defined above, on the contrary, if you ask the right questions and vet the operator thoroughly you should not have to fear this calamity as you proclaim in your statement. 

@Jacob Howell  lastly I bet this old bird has gotten many yellow letters and has told the exact same story to numerous people..

You would be gambling big time!
