I am going to try and go to some of their meet ups whenever work permits the time. 

You have Absolute Liability for your property, you could have claimed ignorance when you didn't know what was going on, but now to allow it you must be responsible for: inspection of the ramp, security of the area, permitted access only, proper safety equipment etc.... if you choose not to be responsible for such things you are still Absolutely Liable.

Be polite, plead ignorance, go get your permits, and move on.

Sometimes i'll sell my note because there are things that I know about the asset or the loan that cause me concern like, there is a toxic DDT landfill on the property or, the 4,000 square foot addition to the property wasn't permitted or, there is no certificate of occupancy or, there was a meth lab in the home or, there is a HUGE senior lien in front of me or, there is so much deferred maintenance that I couldn't ever expect to get my money back or, the well is dry and the cost of $20,000 to drill a new well is prohibitive or, there is an incurable defect, or there are huge property taxes or any number of a million other reasons why I'm willing to sell my note and get out of it by passing the nightmare on to another investor.Moral of the story is, unless you are buying in bulk and have the relationships and track record to support it and unless you have the capital and time and stomach to roll with the punches, a single note purchase might be biting off more than you can chew.

Terrible story but the buyer sites Zillow pics that were date stamped, shouldn't that have raised some red flags when permits didn't show up?

Hi guys,Im planning to build a driveway in my triplex here in Connecticut, there's plenty space and I have all the permits to do it.

The city will not likely be able to advise you on what is needed only the permit process   

Installed a $100,000 dock a couple years ago with all the proper permits Zestimate has not changed in 3 years by more than a couple percent Anyway to let Zillow know in hopes they will increase the zestimate Remains the same as a neighboring house with no dock. 

Still no contact from missing tenants. 7 days pass as I am in and out as my regular job permits to mitigate the damage done.
