The scary thing is that I've been researching tax liens for months yet didn't come across anything about this case until today, so I expect that a lot of other investors are in the dark.

So you had lots of vacancies in the weekdays and then people having parties on the weekends.Lots of locals smoking weed on the front porch / blasting music on front porch, plus worse, that I wasn’t fully privvy too.Airbnb is making it harder and harder to screen Airbnb tenants (a quick Google / FB stalk is impossible without last names / photos being shown).A party starting to kick up at 2 am that you’re watching from your outdoor cams hundreds of miles away and your 450k home on the line is a terrible feeling.Anyone who’s been doing Airbnb long enough has horror stories, big items stolen, thousands of dollars of damage, or worse.

I like that one had not heard that before .. that will smoke them out.. 

So, does it mean that American Modern is better, or is it just smoke and mirrors?

Go over it slowly, highlight the really important parts  and be very clear with expectations and possible consequences.Second-  Do  a walk through video  (3-5 mins) clearly showing the condition of the house at the date you acquired it, open blinds, show smoke detectors, show any damages-- anything good or bad.   

They just smoke weed inside and have kids... so their window is to air it out.

The dark side of real estate syndication that nobody talks about 

Booked a stay with them for a condo on Airbnb.... listed as a nonsmoking property but recent reviews complained of terrible cigarette smoke in unit. cancelled reservation and will not refund deposit. false advertising and hazardous to their guests.

Created en suite bed/bath, extra bedroom/office/playroom, created family/tv room, added a couple of windows in dark rooms, installed new HVAC, ran all new pex lines/valves/shut offs, all new hardwood flooring and carpet, all new and expanded kitchen cabinets, new appliances, converted 1/2 bath into full bath, repurposed 2 unused rooms (1 into a 4th bedroom/office/playroom and one into a family room, installed new interior and exterior lighting, new electric garage door w/remote, and landscaping What was the outcome?

That's a giant red flag for that grocer potentially declining to renew their lease, vegan gluten free customers don't want to walk through a cloud of cigarette smoke to get to their ethically sourced non-GMO organic avocado, and obviously the "no smoking within 50 feet" sign is going to be ignored by the customers of that neighboring business, who are all a bunch of smokers.
