Could I list the properties that my children own as homes and purchase from them, if it came down to not having enough listed properties actually close? 

That being said I try not to rent to families with children under 5 if they are looking at one of my homes with a pool.

HUGE issue with families with children visiting my home.

The original owner passed away unexpectedly ~1 year ago and their children inherited the property.

For example you need a larger house because you suddenly took on three adopted children and existing house is too small, then you show the adoption papers.

Declining an applicant because of family status or number of children may be challenged as discrimination, unless you have a valid reason (e.g. more people per bedroom than the code allows).

When you have children, you will be paying a hefty price for child care and for their activities, especially in the bay area. 

You cannot buy from yourself or any disqualified parties (your parents, your spouse, your children), nor can you let any of those people live in the property.  

Staffing is tough, have more children while you are young.

I accepted a young (20 year old) couple with two children under the Section 8 program.
