In escrow and seller renews a yearlycontract with tenant 15 days

[Daniel Garcia]

Hey team, I was in escrow (have since closed) to buy a duplex and the two tenants were in 1 year leases ending in 4 and five months from closing.

After closing I get an email from my PM saying, hey btw a new one year lease was signed with one of the tenants.

My question is: is there a way to avoid this from happening in a future transaction? 

A clause or addendum to the purchasing agreement? I feel like the seller's PM did the tenants a favor and locked in their rent.

Thoughts and advice greatly appreciated!
