However there may be a ton of things you have to consider and investigate right from the start. 1) What are the zoning requirements for a condo building?

You're right about trying the front door first and I will investigate...Jean

In the beginning, I too felt the need to investigate a "that's not me!"

I am a private investigator and would like to help you.

Much to consider and investigate.  

I'm still looking for someone that has either done this or at least investigated it locally.

The 'monitored without your consent' hopefully refers to homeowner initiated stuff like Ring doorbells, but if the language doesn't make that clear it's worth asking.The 'protection period' is so that untrustworthy buyers don't get an agent to work hard for them for months, ditch the agreement or let it expire, then go on to buy a property the agent helped them find and/or investigate without the agent getting paid for their work.

It would be worth investigating a separate unit/control. 

In short I had a lot of limited beliefs and a very tall very thick wall around me.I investigated Gino through emails, post like yours and even taking a ride up to his restaurant about an hour north of the city.

The real estate attorney I spoke with about this so far has suggested hiring a private investigator to track down all possible next of kin to get them to sign releases...
