I would think it would be best to rent to a single adult since it is just a room for rent and I would keep looking for a single tenant to rent to.

Making dumb moves as a teen or young adult is normal. 

One girl has credit score of 400, her supposed boyfriend has credit score of 650, 2 other adults will also be moving in with them, which is the height of our limit of 4 people per room, I don't know the other 2 credit scores yet but of course I'll screen.

I do not prefer them in the house - the pit bull in any rental is a not only a NO but a HELL NO.I text the tenant and ask him to call me tonight - he does - I ask him about the extra tenant (step daughters boyfriend) amongst other family living in the house above 18 that is not on  the lease - (I'm thinking in this smaller 3/2 house there may be 5-6 adults and up to 4-6 kids living there) - Tenant lies about boyfriend living there. 

Having an adult son or daughter move back in after college or having your mother in law move in when she is old would be permissible, even if they agreed to pay you. 

I’m Isaiah a 20 year old broke inexperienced young adult that is highly motivated to get in this business.

While meeting a pest control expert there, the tenants adult daughter said they threw away their mattresses about a month ago.

A separate Rental Application MUST be completed and signed by each Applicant and all adult Occupants 18 Years or older (Unless a full time student living with parents). 2.

He has one or two adult dogs, that need to be caged in, that's problem one.
