I have no problem enforcing our lease and threatening/going through with eviction, however I'm curious how I would prove that she has additional adults living with her.

location=State%20College%2C%20PA%2C%20United%20States&adults=8&check_in=2019-09-13&check_out=2019-09-15&guests=1&source_impression_id=p3_1559416759_goL%2B2pTfN5vAN7nT&s=nG69S5pr

I explained I still needed all adults over 18 to fill out the application and sign the lease, because there is a criminal check involved also, but it was fine if only one person made the income requirements. 

Coping with the loss of her passing, I wondered , what had made her hold her head high and never ask anyone for monetary help even after we were adults and earning well.

In this case since it is an adult female, doing a closet check should also be an indication. 

I must admit, I am new to the STR scene so any insight as to why I should switch up to shorter term rentals as opposed to longer term ones would be most appreciated.My thought process was, shorter term rentals could possibly lend themselves to young adults looking for a party location and perhaps even older guests that due to the short term rental nature of the stay would care less about taking care of the premises.

I require they have a  year landlord(non related) referene, all adults and that all adults have a  year solid job reference , or disability award proof. 

1 per adult

I'd love to hear some thoughts on the idea of 4 adults as tenants in a SFRThx

I always require all adults over 18 to be on the lease (yes, I've read Brandon's book!).
