Landlord's rights in MA

[Vladimir K.]

My lease with tenants is past due to renewal old one ends on 07/30, they verbally agreed to renew a while ago, but they now start requesting changes to the lease termination terms, which I don't agree to. The lease has the holdover clause that says if they continue to hold the property, the lease is at will, but with landlord's consent.   

Q1. If I want to them to move out of the property on 07/30 as per the original lease, can I request it? They did not agree to sign the new lease, but I didn't send them yet any notices. 

Q2. Our early termination clause says they need to pay re-renting fees and half month termination fee. Does this mean they need to keep paying us the rent until we find new renters or until the end of the full term?

Thanks in advance
