What discount should I expect to sell a note for?

[Joe P.]

I am looking at selling an acre of vacant land with financing but I need the cash so I am looking into selling notes.  I am wondering how much do note buyers pay for notes?  I know this depends on many factors but I am just looking for a ballpark figure of what kind of discount to expect.  Lets just say the sale price was $16500 I've collected a 30% down payment of $5k and monthly payments are around $244 for 60 months at 9.99% interest and it has been seasoned for 4 months and performing.  Market value of the property is $25-$30k.  

Again I know it depends on many factors but I'm just looking for a ballpark figure.  50% discount? 20%? 70%? Would it be reasonable to expect at least $7k?
