They are seeing and interacting with an adult no stuck in generational poverty.What did you have in mind for offering healthy food to eat after school?  

This has been my dream, since I was a child, and I was scared as a young adult, by my parents getting involved with Amway, and the whole dream building thing they did, ugh.

It took me decades of adult life to accept the wisdom, benefit, and opportunity free market capitalism and free enterprise could bestow upon humanity.

Years ago I recall a provision for special needs young adults as well.Paul

@Austin Lee  I don't know about the local market there but 50% of all the adults in the US are single, up from 37% in the '70s according to the BLS (see http://www.bloomberg.com/news/2014-09-09/single-am... )Do you have data that shows 1/1s are bad or is it just a bias you picked up somewhere?

Keep in mind that families on a budget will have their kids sharing a room, so a 3 BR house will be OK for families of 6 (2 adults and 4 kids); that extra room will only be attractive to larger families (unless an in-home office or TV room is needed by the family).So if you pursue that, be sure the local demographics support you getting higher income for your troubles before you do that extra improvement.

If they are acting rude, inform them that their negativity isn't necessary and that you're trying to come to an agreement with them as an adult and you'd appreciate if they would work with you instead of against you. 

Since, you wont have tenants with small kids, how many single adults with no kids exist in this market? 

You may still get into real estate if you have your guardian co-sign legal documents, or in many states there are legal emancipations that can be done so you can do business as an adult. 

Therefore, it could be 2 adults and 4 children.
