Hello,I have a property with a tenant that I inherited when I purchased the property..She is an older woman with adult children that, at one point, moved in with her without notifying me.We've got that all cleaned up, but now she is adopting a 2yo child.It's a noble act, but how does this effect me as the owner?

While it is true you could sleep 6 with a K and 2 Q's you can also only accommodate 3 single adults. 

A single mother of a adult kid with a disability, and a full time nurse, wanted to buy another house.

The ONLY exception would be if, due to substandard work done by a handyman, a child was injured or an adult was severely injured.

There are 1000’smof beach webcams if that was his thing  Hit it with a laser pointer, does he even notice?

This first property is going to be a house hack so I figured I would learn some adult activities and cut the grass myself.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

However, converting these into desirable, owner-occupied homes could capture untapped market segments, particularly as economic conditions improve.Age Distribution and Market DemandDiverse Age Groups: The presence of young adults and an aging population suggests varied housing needs—from starter homes to downsizing options.

But I think we all know not ALL people are rational, and some people / agents / adult-children don't quite get it or hide facts ( fake income statements, etc. )    

Your compassion is wonderful.On the other hand, we all must still be adults and meet our obligations even when we are facing challenges.
