At best, I might agree to a reasonable time limit against acting on a specificproperty identified by address.

Don’t give them the address of the property as this might trigger an event that will cause change.

You may not be able to address issues in a timely manner when they come up.

Sometimes, the address describes a house, but the auctioned parcel is for basically half of the address which is split into two separate lots (one with a house and the other without one). 

If they say no, we ask why, and occasionally, we can sway them if there had been a misunderstanding—for example, a lingering maintenance issue that hasn’t been addressed and they didn’t bother to call about.We don’t have time for a deep dive on lease renewals, but it’s definitely worth picking up a copy of Jeffrey Taylor’s The Landlord’s Survival Guide, which has all sorts of tips on getting tenants to renew.

@David CianciYou and @Sean O'Keefe made me create a long answer to your question:https://www.biggerpockets.com/forums/51/topics/1202208-gray-...Also, beware that @Natalie Kolodij's post that was linked on this thread does not really address your question.

Since the upstairs tenant already addressed it with the other tenant we would wait until there is another complaint.

PM me so I can get your address and I'll send you a copy of the book. 

I worry way more about IF they will pay than to what address.

Depending on your address you may fall into the city's jurisdiction which only allows short term rentals for 90days or less in a calendar year, or the unincorporated part of the county which does not have the restriction.
