So it's not an outright zero tolerance ban but described by the city council members as getting a reign on the unlicensed hotel operations and commercial activity in DC.  

I've lifted  your ban.

There is one town near Mt Snow, for example, that has an outright ban on STRs.

Often a grey area or banned for full time occupancy, though.OP- Please feel free to come back ad post an update on what you've found.

Hellorecently I noticed that I was banned from Facebook market place and I have no idea why.

If you don't live in ATL, move here or look outside the city limits – see caveats:Dunwoody, Sandy Springs, and Brookhaven are effectively banned for everyone.

NYC has pretty much banned short term rentals. 

I'm surprised you haven't been banned yet.And to answer your question, I'm here responding because I have purchased 7 properties in all cash over the years making my personal experience a perfect fit to answer this particular subject as I have first hand experience.

The problem now is that the golden visa has been abolished, Lisbon has gone from cheap to very expensive and new short-term rentals have been banned, whereby investing in Lisbon has become much less attractive.

@Engelo RumoraI have heard that there are laws in the works that will ban investing anywhere in the country except Columbus.
