thanks for the good info. the address of the building is 816 E 90TH PL. something was telling me that my trip to the building department would be unsuccessful ..thanks for confirming my theory. yes the violations require many permits for sure. no the building does not have a red X on it. i believe red X should warn the firefighters about structural damage, previous fire damage etc. what's the process in that case ?

However, it would be very reasonable in a place were units are $5M+.In my area we are supposed to give a warning.

Or report the tenants to the proper department.If there are consequences when they are reported, then after numerous warnings & citations they may move.

I am thinking of a landlord-friendly warn and sunny State such as Florida or Texas with a year-around vacation market location with yearly high vacation rentals occupancy rate that is also STR-friendly short term and long term... 

WeWork's journey, marked by its spectacular rise and challenges, offers crucial lessons for us all.The WeWork Warning: Expansion with CautionWeWork's initial success story was built on the allure of revolutionizing the traditional office space.

For those thinking about making the switch to Airbnb hosting, be warned: the landscape is evolving, and not necessarily to your advantage.This isn't about scaring you off but rather painting a picture of the current Airbnb scene.

Also if you arent a warning incase you see the taxes paid last year from a primary owner you may have to pay more as you wont have that deduction in property value. https://www.phila.gov/services/property-lots-housing/propert... 

WARNING: doesn't always hold up in court:(2) Pet Rent: depends on breed, size and rent amount.

Quote from @Gina Stern: There are ways to deal with these situations, and it depends on the property and the lien holder, but it's possible to do some pretty incredible things if you are willing to invest a little more in legal costs to close the gap on your losses.   

Does anyone have any advice or warning with investing as an LLC or with a partner?
