Are you kidding?

How is the market for selling them on the backend, will families raise their kids in these neighborhoods?

But as my 2 kids get older, the 3BR SFR I'm in feels too small and I'm thinking of moving.  

Her kids pay me directly each month.

I’m not kidding.

Like @Travis Watts  I had a job working for a tech company, but I was never so dedicated, my kids knew what I looked like... :)  In 2010, I saw a presentation about SF and MF at a week-end seminar; SF no, and MF yes -- I could understand how it worked.

Did I mention you have to pay for the tenants food, healthcare, shelter, kids, and more!

We have 5 kids between us so we stay very busy. 

I have a section 8 tenant in a 6 unit building who started dating a registered sex offender, my other tenants are upset because they have little kids and don't feel comfortable with a pedophile near their kids. 

Of that remaining 10%, most of them have a "not technically sales" sales job... a high school teacher is "selling" those kids on studying and doing their homework on a daily basis, for example, and on the notion that Algebra isn't mysterious witchcraft, in fact it's something that you can understand and apply to your daily life.
