I had a great team that I was fortunate to work with.

Fortunately the tenant was amenable to this (in Seattle you can not force them to leave, even to sell...even if their lease ends - not sure how that's even legal but that's a whole different post) and actually decided to leave earlier than their lease date. 

The best of fortune to you in your new endeavor!

That is what my understanding was too, fortunately I did claim the other rooms as rental income for 2020.

In review of it though, my mother-in-law who worked over 30 years in the legal department for a large Fortune 500 company flat out said it was THE worst easement she had ever seen written up in her entire time.

There's not much ventilation so I thought about adding vent fans or windows to the hallways and stairwells as they all have at least 1 exterior wall.A cheaper and easier solution I thought might be a commercial grade air purifier in each hallway and some plug in air fresheners.Every room has 2 vent fans, a window, and a through the wall air conditioner so the rooms have good ventilation but the hallways can get stagnant, especially in the summer when it is hot(no a/c in the hallways and stairwells).Any suggestions that don't cost a fortune? 

But likewise never not do something you know to be right just because it may be questioned.Something like you describe can be a very fortunate accident when it happens once.

Unfortunately for us, but fortunately for the population at large, VB police just moved to a scanner feed that the public can't access. 

I’m looking to move to Brooklyn in about a year when my lease is up and buy a live-in rental and rent out spare rooms or spare units if I’m fortunate enough to find a good deal for a multifamily.
