Any other hints will be valued from others too.

(hint,hint)

I'll give you a hint: "No business entities were found for invesdoor."

Hint.

I realize that I can just go down to the courthouse myself and ask around, but I'm really trying to be intentional and efficient with my time, so I would be very grateful if someone could save me a lot of running around with a few helpful hints. 

Hint: No-one is suggesting it's easy to find such deals.

The old owner hadn't build out the lots to their best potential, so because they are all actually modular units (hint: modular units don't count as buildings but are instead personal property, so the property taxes are WAY lower than what we would pay if they were permanent structures), so we are moving units around (using a large rough terrain forklift with extended forks) and are currently prepping to add 60 more modular units to one of the locations and will add more to the other location later. 

The seller's attorney was a provider of leads and he hinted the attorney gets paid for it.

$700 a year to protect a $20k but I guess maybe no worse than car insurance.Any hints or suggestions appreciated.any suggestions on how to best negotiate this deal?  

Hint, look at solds for past 3 months within the subdivision and also look at active/pending in the subdivision.
