I can understand not wanting to relinquish control for a profitable property.

No, I put 65,000 but its probably worth 140,000 I'm trying to get a HELOC to do some renovations, then rent it out in April.

My partner is an experienced home builder with 40 years of experience, however we recently moved to TN and he is not interested in getting his TN GC license.

You don't want to get stuck with negative cash-flow because you can't find another care facility tenant to rent it.Also, probably want to check with your insurance provider and see if all those tenants who are likely to fall and break a hip are going to be an issue for them, and look into the legality of what happens in the care facility owner dies and you're stuck with 5-8 tenants in the home with no one to care for them and no living descendants.

You would want to check local zoning to make sure you could build more than one as a lot goes into that beyond just being close to plumbing, electric, and gas.When you mention "a lot goes into that beyond just being close to plumbing, electric, and gas," what are the top things people tend to overlook when preparing to build ADUs?

With going rate right now, as I am friends with other owners on my street and have their opinions, I could easily get $1800-$2k/month.

In Mexico, as you know, when you rent to visitors, you generally don't do LTR.

Banks aren't really in the business of lending to real estate investors anyway...they focus primarily on "operating entities", but they can be done.
