@Shannon Slade Yes, the lease specifies that guests cannot stay for longer than one week without my approval (it's been only a few days since the son-in-law's return, however).I have heard from Ms D, who has confirmed that her son in law (and his wife and children, who were all there before this mess began), has indeed moved back in.

The woman seem nice (no children, no pets, no smokers etc.)

In my area, Lucille Packard Children's Hospital at Stanford has a network of property owners they actually refer business to.

I want to provide a nice place for the tenant and her children. section 8 pays very close to market rent.

Hi mick I am also from napa and we left a few days ago due to the smoke and having small children.

Chances are if the tenant is letting the dog tear the place up,  the tenant and thier children and guests are just as likely to do much or more damage.  

If she is licensed, how many children is she licensed to care for, and does that include the other children living in the house (it usually does) Has she done this before at other houses? 

Our homes are worth more than $100,000 most times and more.We jump through a lot of hoops to get our business up and running, and we go through a lot of "stuff" to provide good rental homes to the public, to the community, not mention all the laws we need to learn and obey.When we choose an applicant to rent to, are we looking for children that must be pampered?  

She allowed her two adult children and two grandchildren to occupy the unit with her even though they were never listed on the lease.

Those costs are usually determined by the university itself, and as I understand it, are usually related to the cost of living on campus in a dorm.So buy a property that your children live in, run the property as a rental, while taking some part of the 529 distribution that pays for tuition, fees, etc, to also pay a portion of the rent.
