I think that you will struggle to persuade creditors to accept an early settlement now, if they have the benefit of ongoing contributions and an equity release in two years time when property may well have increased in value further and your mortgage reduced (if you are paying on a repayment basis).
However, if there is any specific reason for the early settlement - ie you are struggling to make the payments due to a change in circumstances, you may enjoy more success. Discuss this with your IP before you get your hopes up too high.
