Losing the interest on the payment is something...Maybe offer them the option of rolling the loan into the next property you buy, giving them an option to refinance an aggregate first for you (well - maybe not if they are weird), or offering them a variation on the "cash for keys" kind of thing....maybe proposing something like, "we are sorry you are losing some income, you can get paid off eventually through escrow on the refinance, or we could pay you off now with an extra small fee for your inconvenience and loss of income from the prior owners' actions "....maybe something like an hour or two worth of legal fees.

I would suggest finding a way to simplify your proposed offering.  

The proposed new law requires a second reading before becoming law.
