She would have relapses multiple times per year.

They may relapse, easily get in fights with other residents, bring in friends "temporarily", etc. 

Habitual relapsers are too much for me to keep the trash away.  

It seems there are risks associated with this outside of doing the job well/right that might need to be factored in here - another person recounted that they hired a carpenter (presumably unlicensed) who did great work but deep into the job had a relapse (drugs) and attempted to extort him.

Even if he has been paying on time and keeping up with his bills he will soon relapse so you do not want this tenant.

Unfortunately they relapsed and I’m currently house hacking in a different property I’m just not sure what are the steps I can take to collect the rent and bring the mortgage up to date until they get themselves back on track.

Hence, you need to think about the time value of money in terms of purchasing judgments and the uncertainties should they become unenforcable (as mentioned), the defendant(s) relapses, etc.

I can see if you have a sick family member, that would make sense with a relapse a year later.

and stash for additional cash reserves.Concerned in the current politicized and medical climate there may be a mutation or relapse (or MSM-fueled rumors of them) which could chill the market again in the Fall or Winter.

:mrgreen: I'm also in the Reformed Hot Rodders Club, but I'm definately planning a relapse :D
