What would a fair offer be?

[Christopher Brainard]

I have a note that I'm looking to buy - the property is in rural Nevada, so not a desirable area. Current balance on the note is $980k, interest rate is 6%, payments are $10k/month, 9 years left on the note, balloon at the end for the remaining balance, which I calculated is around 300k.

What would be a fair offer to buy this note? I'm interested in clearing the underlying debt on this property at a discount, but I have no idea what type of discount I should be asking for.
