Upgrade to a commercial-style stackable setup that can dry faster (30–45 minutes), hopefully fitting in our existing laundry closet without extra electrical work.Any recommendations or specific brand/model suggestions for handling this high-volume, semi-commercial laundry?

What is not helpful is the assumption that some responders made that the root cause is the PM's communication style was not to my "liking".

So you sacrificed your own success because of something completely unrelated to the tool that would make you more successful and faster. 

I think the biggest mistake that people make, is thinking that investing in STR´s is some totally different style of real estate. 

Individualized container homes would be ill suited for assisted living style care.

This way, if someone feels rejected unfairly, you can show that your decision wasn’t based on any illegal discrimination, but on consistent standards applied to everyone.Alternatively... you could just ghost applicants but that's not always everyone's style lol 

I am in discussions to seller finance a townhome-style quadplex.

I would pick a market area you like and start doing a bunch of deep dive deal analysis, but from a rental and not a life style standpoint.  

The goal of the first 3 deals will be to target 1-4unit styled homes, requiring minor-rehab.

Rather, they are four former commercial real estate brokers, with one of them also an attorney in their 60s or 70s that have a true hands-on style of mentoring.
