Over-the-counter (leftover) purchases
unsold properties
Washington counties keep no standing over-the-counter list. Parcels that draw no sufficient bid are struck to the county in trust for the taxing districts as tax-title property. The county resells that inventory under chapter 36.35 RCW, usually at a later sale at a minimum price fixed by the county legislative authority after three weeks of published notice, and in limited cases by direct sale without bids, including within twelve months after a failed auction. Whether any tax-title inventory exists, and how this county sells it, must be confirmed on the county's tax-title or surplus property page.

County notes
- Redemption cutoff, quoted from the county's Tax Foreclosure Sales page: "Parcels being foreclosed can be redeemed by their owners, or other parties with recorded legal interest, through the close of business on the day before the sale." This matches RCW 84.64.060/070.
- The Bid4Assets storefront URL changes per sale (the 2025 sale used /storefront/WhatcomWANovDec25; the county's Auction Process page still links an older /storefront/WhatcomWADec22 slug that now shows a distraint mobile home auction). Always route investors through the Treasurer's Auctions page at https://www.whatcomcounty.us/372/Auctions for the live storefront.
- The 2025 sale required a $2,000 bidder deposit by electronic funds transfer; the winning bid also had to be paid by electronic funds transfer.
- Unsold parcels from the December 2025 auction were re-offered in a January 26-27, 2026 online re-offer sale, so a second-chance sale can follow the main November/December auction.
- The Treasurer also runs separate tax-title and surplus property sales (https://www.whatcomcounty.us/393/Tax-Title-Surplus-Sales) and personal property distraint auctions; deed types differ (tax deed for foreclosure, Treasurer's deed for tax-title, warranty or quit claim deed for surplus).
- Mailing address for correspondence is PO Box 5268, Bellingham, WA 98227-5268; tax payments go to a separate lockbox (PO Box 34873, Seattle, WA 98124-1873).
Washington rules
- Redemption
- Any property on which a certificate of delinquency has been issued may be redeemed at any time before the close of business the day before the day of the sale. Washington has no general post-sale redemption period: once the treasurer sells the parcel, the sale is final for a competent adult owner. The one exception protects minors and persons adjudicated legally incompetent, whose property may be redeemed at any time within three years after the date of sale, on payment of the amount for which the property was sold plus interest at the statutory delinquent-tax rate from the date of sale, plus the reasonable value of improvements made in good faith on the property, less the value of their use. No fee may be charged for any redemption.
- Deed deposit
- For an auction conducted by electronic media, prospective bidders must deposit funds with the treasurer to participate, deposits of non-winning bidders are refunded within ten business days, and payment is by electronic funds transfer. Deposit amounts for in-person sales are set county by county, so confirm the figure on the county treasurer page or the auction platform terms.
- Surplus proceeds
- If the winning bid exceeds the minimum bid due on the whole property, the excess is refunded to the record owner. The record owner is the person who held title on the date the certificate of delinquency was issued. Surplus unclaimed within three years of the sale date is deposited in the county current expense fund, after which the claim is extinguished.
A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
