I tell people it is like "Adult Monopoly". 

If you give her the same information as you did her brother, she might begin to see the light.Whenever it's a probate or willed property with siblings (who are adults and have kids of their own) that always seem to run afoul for investors.

I put on the lease the number of adults and children that are on the lease and that no more should reside there or else I can terminate the lease. 

Were any of the other members of the household adult?

I am over 800, and have been there most of my adult life. 

Since we were still young adults, we thought we had it all going for us.

So far this looks to be a fantastic community of dare I say adults?

Ended up doing banking for a little after college than got into construction management. after 1 1/2 got laid off and spent 6 months figuring out how to be an adult.

You would not believe how many times I ignore inquiries from supposed "investors" seeking information about my rates and requirements, because they can't communicate at an adult level.  

sure sucks that beauracratic entities can't seem to be okay with a property purchased for rental income for 2 years then expected to be exchanged after the 2 years since most young adults nowadays nationally tend to move every 2-3 years whether tenants or owners alike.
