@Luke Chung Congratulation on the property and the health of your son!

@Kapil Patel, aah, the age old dilemma: how can I live for free, and, without working?

There is VERY limited housing around here, so people who have housing vouchers can hardly find a place to move into and those with mental health are essentially screwed.

I suppose this could happen with any seller regardless but I am also concerned given his age and ill health, what if at the time of purchase his interest in in probate or held by surviving family? 

To cover myself, I added the following provision to my lease..."... when needed to water the grass, Tenant agrees to allow use of their paid water to maintain lawn health and appearance as needed."

But that was the dilemma 4 years ago too. 

Again, not mandatory but seems to be more common as the concern increases about the health issues related to cesspools.Mark

The other part of this puzzle is his mental health.

I have worked in mental health for years and we regularly receive permission from clients to use their likeness in promotional materials.

We needed a permit and to be registered to remit room taxes (the name of the permit eludes me at the moment) and we also needed a health inspection and permit from the Health Department.
