Monies received by the county treasurer at resale from individual purchasers, not redemptioners, shall nevertheless be deemed to be collections of tax, and if no redemption be had before issuance and delivery of a deed therefor, the tax monies so collected, not including excess proceeds to be held for the owner thereof, shall be credited and apportioned as such taxes would have been apportioned had they been paid in the proper time and manner, and the monies so collected representing penalties on ad valorem tax, listing fees and publication costs shall be credited to the “resale property fund” of such county as hereinafter provided. In instances where vacant lots are offered for sale for both ad valorem taxes and special improvement taxes, but are sold for less than the total sum due, the county treasurer shall, after deducting the listing fees and publication costs, apportion the proceeds of such sale ratably between the ad valorem and special improvement tax accounts in the same ratio such proceeds bear to the total tax published as due for such resale.
