New Owners, need to give notice to tenant for Rehab

[Angela Smith]

Purchased a triplex from an owner about a month or so ago and the owner told all the tenants that they would need to leave by x date (in June). We are now in the possession of these properties and all but one tenant signed a form stating they would vacate the premises by a certain date. These properties are dilapidated and we need to start rehab mid June. Is there a staple form or example for how this is to be worded, a notice to vacate for rehab or else eviction?
