Hospice _ 501(C)3 charity renting SFH providing hospice care

[Zigmunt Smigaj]

A local charity wants to rent my SFH in order to house up to 3 patients along with a 24 hr staff. This would be a hospice home designed to provide more comfortable living in last few days/weeks of life. What additional considerations should I put in place or ask about. My property is in a residential neighborhood, zoned residential. It was explained that they're not running a for-profit since no rent or fees are charged to the patients, the company has a large donation pool that covers operating costs and staff.

Should we put this property into a LLC or REPT?

Could this affect a later sale? 

 Should we draft an addendum to the normal PM agreement? 

What tasks would you ask a lawyer to perform?
