Below are some that I have seen all types of multfamily on.LoopNet, Zillow (recently saw a 34 unit property for sale, Redfin, Realtor.com, Craigslist (very uncommon but happens), and Auction.com. 

That is not an uncommon practice in Airbnb. 

It's not uncommon to have insurance bookings that start as shorter stays but then get extended as the guests wait through construction delays, permitting, etc. 

@Marcus Robinson Sadly this is not uncommon.

Millionaires are not uncommon, because it's just not all that much $ anymore. 

I'd thank them for the great review about the house and say you strive for 5 star reviews in the house.I'd say the idling train in an uncommon event and that your sorry that this anuance happened to them. 

on the flips side I made a 500k flip fee on a 14 lot development.. but I did put up the 50k EM and I did spend about 75k getting it pre plat approved.. then builder closed once all appeals were exhausted.. but I was also prepared to close if he tried to back door me or go around me.. which is not uncommon when you get into the bigger money players.. at the time I did not even realize wholesaling was a thing or you would call it that.. maybe it was a development wholetail since we did put up 125k of risk money :)on the one I just paid the 125k to someone else we have an offer on the table right now from lennar which is a 1mil profit. but again I put up by the time its done 325k to get there.. the mil we get our 325k back then a check for 1 mil if the stars all align .. we could lose 325k also.. rapid appreciation like this I guess those that call appreciation gambling maybe that's exactly what it is... gun slingers.. take me a long time to make 1 mil in a year owing rentals though  LOL..

Is it uncommon for agents in the St.

While this sucks and sounds like you have a bad landlord, noise between units is super common, especially in older buildings and you would not believe the required STC rating between units/floors is very low - and its not uncommon to hear others. 

It is not uncommon for owners not to want to waste their time and disturb their tenants any time someone says they want a tour.
