No on the disposal - they get abused and cost you in plumbers coming out to clear drains. 

Both names are on the lease.Over the weekend, one of the individuals texted me saying that she wants out of the lease and she has moved out already bc the realationship turned abusive.

Ah different asset class than the majority of posters on BP.its typical in our portlandia market for b to a apartment complex's that management fee is 4% .. and you pay for your on site manager to handle the day to day etc.. the PM company manages the on site manager and makes sure they are not abusing the owner.And your absolutely correct turn over kills cash flow absolutely kills it ... when folks use a 5% of gross for vacancy many times that numbers of off buy 100 to 400 % of actual .a long with maintenance.. if your having turn over every 12 to 18 months ( very common in many areas) your cash flow is probably neutral if you actually figured it out.for me personally and I am retiring from land lording  the last of my 11 or so A class SFR's I never raise the rent and when they move out I sell it. when I was running them my rents were always below market... this allowed me to only pay a RE broker a placement fee and my secretary could do the day to day.  

However, acting immediately for the safety of the abused Grandpa is paramount.

It has been my experience that if they put off paying that long, they are also abusing the rental.

You're a bit too nice, nothing wrong with nice, it works out just fine when the other parties play nice, but this tenant you have is a user and abuser, she takes advantage of nice and will continue to until you train her otherwise.  

They were called "miner-sexuals" around town  :)I had a fellow cop friend who epitomizes what BP is about, earn serious coin (bought out 7 years of pension) by renting to these folks.

Let some other landlord take chances on her.I can tell you from first-hand experience (not me) that women who end up in abusive relationships, do so regularly.  

During the term of the lease (the initial term of the lease or any extension term), the owner may only terminate the tenancy because of: (1) Serious or repeated violation of the lease; (2) Violation of Federal, State, or local law that imposes obligations on the tenant in connection with the occupancy or use of the unit and the premises; (3) Criminal activity or alcohol abuse (as provided in paragraph c); or (4) Other good cause (as provided in paragraph d).

The numbers speak to themselves and the tenants do not abuse the utilities.
