Unfortunately nothing....I've never heard of a vendor loan, at least not in the mainstream of business. If it were VendorFinance.com or Vendorfinancing.com you'd have a much better chance of monetizing, since those would signify an actual service available by many vendors (even then it'd be difficult).
On the flip side, you purchased this domain so I'm sure you'd probably find someone on namepros who'd eventually purchase it like Ben Pedri suggests.
Good luck tho!
