If you are a Catholic Latina female and want to rent to only Catholic Latina Females, then that's allowed. 

@Elena Pech they should get liability on their renters insurance and if these are working away from home adults I suggest no puppies.

I believe the rental market will be strong in the coming years partly because the younger generation of adults are less likely to "settle down," and the price of home ownership is significantly higher than it was just five years ago.

That being said, at least in FL, you can have in the lease application that all adult occupants must be on the application.

Adult kids with limited funds vacationing with Grandma and Granoa who are footing the bills.  

I read some post on BP where they were suggested to charge more rent for 3 adults, but if that's not okay I'll not do that . 

I had a case where a resident had been severely attacked by a dog as a young person, and as an adult was VERY panicky whenever surprised by a dog.

If the tenant feels threatened by a roommate, they should work it out like adults or report it to the police.

The secret life of bees: Children put things in sinks and toilets without adults noticing.

I want to know what the healthy line of mediation is, and basically I want to remind them that they're in leases so they have to be adults.
