Or how about 4 adults saying they want to share the bedroom.I guess my question is can I discriminate against children or number of residence if the building is unfit for families.

Adult cruises sprinkled in.

Even the judge found that ridiculous and ordered us to "behave as adults" and to come to terms. 

I listened to a podcast a while back with an investor who exclusively rented to "group homes" (homes which were rented by an organization that provided room and board to adults).  

They certainly are not going to add your property to their list of available housing for students, but all gave me suggestions on how to advertise vacancies to inbound students, and note that many students (think professional studies) are adults with families, who are seeking accommodations that are family-friendly (one housing rep flat out told me that they run out of family accommodations months in advance and always get asked about help finding housing around the schools)...Food for thought.  

Make sure the daughter who is living there, but not on the lease, knows (not sure if this is the one you talked to or if she's an adult-guessing so). 

My husband, adult son, and I live here so we want to be cautious. 

I think it's great for young adults to even be thinking about REI at that age, though - totally amazing. 

It’s like babysitting adults

Also, note, that if you have another adult in your household (spouse) you can each have up to 10 personal conventional notes - this will give you the ability to acquire 20 units at a time and move them to portfolio commercial loans into your LLC.This should resolve all your questions.
