Even the sweetest family pet pitbull could go crazy and kill a child who snuck up and scared them.

and the tenant is responsible for all liability of the animal and a "hold harmless" for you the owner..What if this dog get loose and hurts a neighbors child?.

I wondered if her disability affected her ability to complete the app.For what it's worth, I can appreciate a prospective tenant informing me about an adult child who might be staying with them at intermittent times.

Its kinda like a spoiled child  you have to be firm, and don't give in if you know you are right. 

Her 5 year old child was pretty wild and fairly defiant but she seemed well put together and professional.

Grown-ups expect them, and will often offer something in return to the party they have offended, in whatever way that may be.But, for someone to expect to be able to offend someone in whatever way, without any consequence, is immature at best.It's right and proper to expect grown ups to act like grown ups, and to honor their grown up contracts and grown up consequences for breaking those contracts.Expecting less, is to treat someone like a child, and to consider yourself their disrespected parental doormat.

That extra $1000 per month could become child support very quickly. 

Some small child will walk in the open gate, climb up on the platform and fall in the pool and drown.

If part of the income is child support, I want to see a bank statement showing it is actually being paid.  

You certainly don't want a child playing and have little hands accessible to wiring.
