Inherited Tenant Welcome Package

[Robert P.]

I will be closing on a 3 family shortly. All tenants are at will. I am located in Massachusetts. I will have a welcome package to introduce myself including:

1. Welcome letter

2. At-Will agreement with rent amount, due date, where to send, etc

3. pet addendum, so they won't have any more pets, etc

4. property "rules" - how to request repair, what is not allowed, etc

5. Gift card to local pizza business

Question: Do I need to give and have them sign a lead disclosure as the new landlord? Technically they should have already received that when they moved in from the previous owner. Do I need to re-issue since it's a change of owner?
