Valuing a note for sale

[Jess Hewitt]

I have a note that I would like to sell.  Help me arrive at a value.  Here are the details

Original Note:  $48,500, 8% interest, 30 years, secured by first lien on $70k property, typical note terms.

Date: 12/9/2009

Current Value:  $41,505

Payments:  $505.88/month includes $120/month escrow for insurance and property taxes, No payment missed, 3 payments late but not by more than 30 days.

Escrow:  -$800 now but payment will be increased for negative balance and increased taxes/insurance.

My guess is its worth $55,340 valued at 6%
