Need estimate for a single performing note

[Tim Silvers]

Am putting together a seller finance deal where I would be holding a first lien position and would be looking to sell the note. Here are the following stats:

1st lien face amount: $38000 

Current Market Value of subject property: $50000

APR: 8.00%

Term: 72 months, fully-amortized

Pre-payment penalty: none

To assess the exit strategy, what would be a reasonable expectation as to its liquidation value? I realize that letting the note season for a minimum of six months may add to its appeal. If there are any online platforms for estimating note valuations, I'd appreciate a posting of the links.
