They are in their 60s now and have adult kids , but just those two smallish buildings were able to create generational wealth.

Maybe having an adult conversation with the man will help you make your final decision. 

I knew way too many people to party their way to a 6 year bachelor's degree in something they don't use, living with parents and still basically adult children.

IE, split male and female, homeowners and investors, etc.

The partiers were not residents, it turned out one adult tenant had been marketing "pool parties" to non-residents at $5 a head.We have a "no parties" clause in our rental agreement, and also do not allow residents to run businesses on the property. 

That's when the upper unit tenant called me, as he's never really had this problem before and really didn't think he needed to call me because they are all adults but felt it was a big enough issue and now he is thinking about not resigning the lease for next year.  

I was told by the district's planner that a residential facility which houses 3-5 Unrelated adults is permitted in all districts except Limited 1 Family.

I’ll be glad to.Issue:Being Female.Being a black naturalized citizen, female at that.What is it with contractors and working with women?

If this remains the case, what are her or her adult son's options if this remains the situation after his passing?

Between student loans, bills and just adulting, it would take me years to comfortably fund this investment.
