HUGE issue with families with children visiting my home.

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

My goal is to buy a house hack when I move next year back to my hometown after finishing dental school.

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. 

An example is Aspen Dental, T-Mobile, Starbucks with 10 year primary leases with 10% rental increases every 5 years.

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.
