Hold on, OP, hold on.
The prospective owner must honor the obligations of the current owner.
That is to say, the duties owed to the current tenants by the current owner are assumed by the new owner WITHOUT EXCEPTION.
The prospective owner can offer CASH INCENTIVES to PURCHASE the leasehold from any existing tenant. The tenant is FREE to refuse all such offers.
I've been where you are about to be.
Trust me, money talks.
You INCENT the "problem child", he or she will eagerly vacate.
Think about this.
If the rent is $500 a month.
The eviction will cost you at least $4,000, plus legal fees.
You dangle a couple thousand quid in front of him or her, they'll salivate and agree.
Never pay until they leave, and get it in writing, signed, and properly witnessed.
No cash until they're off the premises.
Problem solved.
Be careful in using the term PROBLEM TENANT.
WHY?
That tenant could become a PROBLEM PLAINTIFF!!
