My wife and I manage 26 LTR’s by ourselves, have done numerous flips over the years and raised 3 children all while I work 60-80 hours a week in my “regular” job.  

Do your children want to inherit this house?

She also said he has no immediate family (parents, siblings, children, spouse).

I payed 20k to get educated in something that will make me that hundreds of times over, not to mention I got my money back… Once you get your first rent check, I promise you that you will be thinking “What was I so worried about” My point is investing is the best thing you can do for yourself, your spouse, your children.

People with children are more concerned about family safety than a renovated property.

1) adults are more responsible than children, 2) having a group of people will force accountability on the property.

What about the single mom of three children that can't afford to buy a house and still feed her children.

We invest in single-family homes in Southwest Washington (State), and the SFH I'm writing about is located in Vancouver, Washington.We have a tenant (a mother and two high school age children) that have been excellent during their 1 yr lease. 

It's a family of 7, so I'm assuming 5 children.

Depending upon the circumstances, however, such a limit may be challenged, and anything less than two persons per bedroom may violate fair housing laws by having an adverse impact against families with children.
