Property Assessment doesn't show sale price

[Joe Kelly]

Hello all, I recently bought a property from a family member which was seller-financed back in October. However, I noticed on the county's property assessment website that the sale price is listed as a zero dollar amount. We ended drawing up the contract and QC Deed ourselves and then had it recorded at the registrar of deeds. During the transaction, no monies were exchanged. What did we do wrong and how do I get that corrected? Thanks.
