I really do not like 5 adults live in my property as there will be too much hassle and too many parties, cars, too many boyfriend/girlfriends not on lease....But do not know how to avoid them without being accused of discrimination. 

I have talked to the Hendricks County Assessors office a few times and it sounds like if you designate a property as a rental with the county they say it can (depending on the area and the current assessed value) save you money on real estate taxes.

Lots of cars and trucks parked on the road.If you are the type of operator who notices this in tough times and wants to vet everyone and get pet rental $$$, these maga-families might move to a cheaper, easier abode.I've seen 14 related adults (over 18) in a 2 bedroom apartment (they thought secretly) only one working the rest looking for work.My thoughts are "Flexibility" as an owner in "Tough Times" might help with keeping the rental vs losing it to the bank (like happens to so many during these times).Just my 2 cents.
