I do want to point out that there are reasons why I want to keep the discussion simple and not go into a Monthly IRR which will wind up becoming a much larger Math discussion.I know from teaching classes for the around 10 years to Educated Adults, when it comes to Math, especially complicated financial math, despite the fact that it will make them millions, their eyes glaze over and fall asleep.

adults=2&children=...

I had a deal fall through with a buyer client of mine for an HPR with a basement unit after schlepping to the deed office to look through HPR docs, only to find a restriction on more than two unrelated adults living in the property.

Require background checks on all adults living in the house.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

These kids grow up from teenagers young adults and naturally gravitate towards the suburbs.So stop calling me gentrification cuz it's not.

At the prime of my cold calling from an outsource perspective I had 16 half way house females  Basically they were in jail at night and called for me during the day. 

For safety you could rent out to female RN so it's (hopefully) safer to spouse/family.

I’m 69 years old and have been in the Real Estate industry for my entire adult life.

There are many sports programs out there for youth and adult athletics that could act as long term tenants which would be great in ensuring people actually care about the place and that it produces income.
