ORS § 221.925
In making a deed for any real property sold for delinquent taxes, it is not necessary to recite or set forth the proceedings prior to the sale, but it is sufficient, if it substantially appears from such deed that the property was sold by virtue of a warrant from any city referred to in ORS 221.906, and the date thereof for delinquent taxes, and the amount thereof, together with the date of the sale and the amount paid thereat by the purchaser. The style of the warrant for the collection of delinquent taxes shall be: "In the name of the city (or town) of______." The warrant must require the marshal to forthwith levy upon sufficient property of the person or persons owing such taxes and sell the same in the manner provided by law, and return the proceeds of such sale to the city treasurer and the warrant to the recorder, with the doings of the marshal indorsed thereon, together with the receipts of the city treasurer for the proceeds of such sale as paid to the treasurer. The warrant shall have the force and effect of an execution against real and personal property, and shall be executed in a like manner, except as otherwise provided by law or this section. Real property when sold for delinquent taxes may be redeemed in like manner as real property is redeemed after sale thereof for county or state taxes, and not otherwise. The deed of the purchaser must express the true consideration thereof, which is the amount paid by the purchaser, and the return of the marshal executing the warrant must specify the amount for which each lot or part thereof is sold, and the name of the purchaser.
