If you want to rent to generation X's who are more established in their careers, married, with children, then these areas would fit the bill. 

Lastly, does everyone who lives inside the 285 corridor send their children to private school?

His numbers are also going to be look deflated as I doubt he and/or his 2 children that live in the building currently pay any rent.As an aside, I know that a woman in the building has some sort of rent control situation going on.

Owned by the two children that wanted nothing to do with it and because of that left the rent far below market.

And the tenants have a better chance of affording the utilities so they have enough left for rent.Also less children so much less damage.Also in some areas I have seen a lot of old large homes for cheap.By the time you bring them up to code and fix everything for a good long term rental.You have invested more money in them that what it would sell for.So the only ones it works for are the true slumlords.Just have to be careful what you buy.

Unless yours is a designated 55+ community, you can't decline an applicant for having children, or a specific child.

Many of them just enroll their children in a better district free of charge.

Their problem (which became our problem) was that they had older children who began spitting children like they were PEZ dispensers and dropped them off at mom and dads to raise. 

but like having small children or dogs living in your home, you have to "guest-proof" your home if you're going to have people coming through.

It's been my lifetime dream to be my own boss and invest in myself to give my children the life they deserve.
