When setting the sale price of a loan part, the seller should take into account the speed at which a sale is required. Other loan parts may be available and the seller should also consider these when setting their own price.
As a seller, you can demand a high price if the loan has been performing and the initial interest rate bought is higher than currently being offered by new loans offerings. The term left to run on the loan part will also have a part to play in attracting buyers. See more in ‘How to buy and sell in the Marketplace’.
A note on coupons:
When the loan part was originally purchased, there was a set rate of interest to be paid by the borrower. The ‘coupon’ is the underlying interest rate that the borrower is paying on the loan part.
