On the other hand, I definitely would not have been open to renting my house out to 3 adults and 2 children in a home that only has 1 tiny bathroom!

Generally these are people that either (A) had children very young or (B) do not generate sufficiently income at their jobs to save enough to buy.(5) Lack of Credit. 

Basically designed to protect families with children.

Again I refer back former cash only example and had I started in my 20's without being married or having children, then I would have been well on my way with a cash only real estate endeavor.  

On the other hand, if the end buyer has children that are in or starting elementary, they could walk across the street to get to and from school.  

According to the obit, her husband has passed, and she didn't have any children.

for a family member to occupy 1-2 months out of the year so that they can spend an extended period of time each year with my children. 

To be truthful I want to create a lifestyle not only for me, but for my children's, children's, children's benefit; so they can benefit from the work I put in today. 

(Currently no children, not married) 

Hopefully I can cull out any problem children and still keep the overall number manageable after retirement...
