Proper procedure for letting NJ tenant know you are selling

[Chris L.]

Jersey folks...I may be selling my rental property in NJ in the upcoming months and would like to know if there is a particular form letter you would use or certain procedure one has to follow to inform tenant they need to move out. The tenants yearly lease expired over a year ago and she is now month to month given a new lease has not been written up. In the lease it states I have to give her 30 days notice. I am going to give her 45 days so she has time to find a place.  Are there specific rules around how we have to give notice or a specific document I can use?  Any input would be appreciated. Thank you
