Tax & Foreclosure Auction Platforms — Overview

Scope & neutrality. This is a comparative reference on the third-party online auction vendors that counties hire to conduct tax-lien, tax-deed, sheriff, and foreclosure sales. It is not an endorsement, ranking, or recommendation of any vendor. The wiki is not affiliated with, sponsored by, or paid by GovEase, Bid4Assets, RealAuction, or any platform named here. Every factual claim is tied to an official platform page or an official county page actually retrieved on the date in the front matter; items that could not be confirmed against such a source are flagged needs_verification. Platform rules, fees, and county rosters change frequently — confirm against the platform and the specific county before bidding.

Overview

Most US counties no longer run their delinquent-property sales from a courthouse podium. Instead, a county contracts with a private auction vendor that hosts the sale on a web platform: bidders register online, post a deposit, and bid through the vendor’s interface, while the county (or its clerk/treasurer/sheriff) remains the legal seller and issues the certificate or deed. The vendor supplies the software, bidder onboarding, deposit handling, and bid mechanics; it does not set the substantive law (redemption period, interest cap, surplus waterfall) — that comes from the state statute and is documented on each jurisdiction page.

Three vendors dominate the tax/foreclosure space, with differing footprints and auction mechanics:

VendorFoundedPrimary product linesTypical sale typesBid mechanic seen

Sources for the table: GovEase official site (states served, “860,000+ parcels sold since 2015”); RealAuction official site (“Founded in 2004… over 1.5M online auctions”); Bid4Assets official FAQ + county pages. See Sources. The Bid4Assets founding year was not stated on a retrieved official page → needs_verification.

Key distinction. GovEase and RealAuction both run interest-rate bid-down lien sales in lien states (the bidder willing to accept the lowest interest wins), which is how Alabama-style tax-lien auctions work. Bid4Assets is most visible in deed / tax-defaulted-property sales (notably California), where the bid runs up to the highest price and any overage above taxes and costs becomes surplus-funds. RealAuction additionally runs mortgage-foreclosure and sheriff sales (RealForeclose) that GovEase and Bid4Assets do in narrower slices.

Where it’s used

Platform-to-county mapping is not centralized — a county chooses its vendor, and the only authoritative confirmation is the county’s own tax-collector / clerk / sheriff page. Below are usages confirmed against retrieved official sources.

GovEase

GovEase’s official site lists operation in roughly 14 states: Alabama, Arizona, California, Colorado, Georgia, Indiana, Iowa, Louisiana, Mississippi, Oklahoma, Pennsylvania, Tennessee, Texas, and Washington (GovEase home page, retrieved 2026-06-02). County-level confirmations retrieved:

  • Baldwin County, alabama — tax-lien auction conducted on GovEase; interest bid-down starting at a 12% cap, 1% decrements to 0%; 10% deposit (Baldwin County Revenue Commission page).
  • Harrison County, mississippi — tax sale conducted exclusively on GovEase; W-9 + certified-funds deposit at the Tax Collector’s Office (Harrison County Tax Collector page).

Bid4Assets

Used widely for California tax-defaulted property auctions and various sheriff sales. County-level confirmations retrieved:

  • San Joaquin County, california — tax-defaulted public auction on Bid4Assets; free registration, $5,000 deposit +$35 non-refundable processing fee; deeds issued by the county within 60 days (San Joaquin County Treasurer-Tax Collector page).
  • Los Angeles County, california and Philadelphia County, pennsylvania sheriff tax sales are hosted on Bid4Assets storefronts (Bid4Assets official county storefront pages).

RealAuction

Used heavily for Florida tax-deed and tax-certificate sales and for tax-lien sales in several lien states. County-level confirmations retrieved:

  • Orange County, florida (Comptroller) — tax-deed sales run on RealAuction; registration and advance deposits required; research, bidding, and final payment online (Orange County Comptroller page).
  • Garfield County, colorado — tax-lien sale on RealAuction; $75 registration deposit by a posted deadline; interest set annually by the State of Colorado (Garfield County Treasurer page, via official-site corroboration).
  • Allegany County, maryland — tax-certificate sale on RealAuction; $50 refundable registration fee; direct-bid format (Allegany County FAQ — text not extractable from the PDF on retrieval; treat county-specific figures as needs_verification pending a clean fetch).

Many counties are not on any of these three and either self-host or use a smaller vendor (e.g., regional platforms). Always verify the platform on the county’s official page before assuming. A county’s vendor can also change year to year.

How it works

The four-step flow is broadly common across vendors; the details vary by county, which is the single most important caveat on this page.

1. Registration.

  • Create a free account on the vendor platform.
  • Counties commonly require a W-9 and county-specific documents uploaded through the portal (confirmed for GovEase Alabama/Mississippi sales).
  • Registration closes before the sale — often days ahead. Late registration = no bidding.

2. Deposit.

  • A refundable bid deposit is posted to the vendor (or, for some lien sales, certified funds to the county office). Amounts are county-set and vary widely:
    • GovEase Alabama (Baldwin Co.): 10% deposit.
    • Bid4Assets California (San Joaquin Co.): $5,000 +$35 non-refundable processing fee.
    • RealAuction Colorado (Garfield Co.): $75; Maryland (Allegany Co.): $50 registration fee.
  • Bid4Assets: a single deposit qualifies you for every item in that county’s sale, but deposits are not transferable between counties — each county needs its own deposit; refunds are issued (typically minus a ~$35 processing fee in most cases) via eCheck (Bid4Assets official buyer FAQ).
  • Deposit deadlines are firm (Bid4Assets: by 4:00 PM ET / 1:00 PM PT on the posted deadline; San Joaquin certified funds/wire ~one week before the sale).

3. Bidding method — depends on sale type and state law, not just the vendor:

  • Interest-rate bid-down (lien sales): bidders compete by accepting a lower interest rate; lowest rate wins. GovEase Alabama starts at a 12% cap, 1% decrements to 0%. RealAuction runs bid-down in lien states (e.g., Colorado, where the rate is set annually by the state).
  • Price bid-up (deed / tax-defaulted sales): highest price wins; overage above taxes and costs becomes surplus-funds (Bid4Assets California model).
  • Direct bid (RealAuction): each participant enters a highest acceptable bid; the high bid is awarded (Allegany County MD model).
  • Timed lots: GovEase keeps each parcel open for a short window (Baldwin Co.: ~30 seconds, extended ~10 seconds on a last-moment bid) — an anti-snipe extension.

4. Payment & deed/certificate delivery.

  • Winning-bidder payment is typically due quickly: GovEase Baldwin Co. requires full payment to GovEase by ~one hour before close of business on the final sale day; Bid4Assets/San Joaquin requires settlement before the deed issues. Many Alabama/ Mississippi GovEase counties route final payment through the county tax office, not the vendor.
  • Delivery: the county — not the vendor — issues the legal instrument. San Joaquin County issues the tax deed within 60 days; lien-state counties issue a certificate subject to the state right-of-redemption. The vendor’s role ends at confirming the winning bid and collecting funds; title, recording, and any quiet-title-after-tax-sale follow the jurisdiction’s rules.

▸ For Investors / Operators — The platform sets the mechanics (deposit, timing, bid type), but acquisition economics are governed by the underlying state statute: interest cap and redemption period on lien sales, the surplus waterfall and deed-seasoning timeline on deed sales, and lien survival in either case. Confirm the specific county’s vendor, deposit deadline, and payment window on the county page before committing capital — these are the details that most often disqualify a bidder or strand a deposit.

Practical notes

  • The vendor is not the law. Redemption rights, interest caps, surplus distribution, and notice requirements come from the state/county page, not the platform. The same vendor runs very different sales in different states.
  • Deposits are per-county and time-boxed. The most common avoidable error is missing the deposit/registration deadline or assuming a deposit carries across counties (it does not on Bid4Assets).
  • Fees: Bid4Assets charges a non-refundable processing fee (commonly ~$35) and deducts a similar amount on refund in most cases; some counties add convenience fees for card payments (Harrison Co. MS: 2.25% non-refundable on credit cards). Vendor fee schedules change and are county-configurable → confirm current figures on the platform (needs_verification for any specific dollar amount not re-checked at sale time).
  • Bid-down to 0%. In interest bid-down states, popular parcels can be bid to 0% interest, meaning no yield if redeemed — the return then depends entirely on acquiring the property if the owner fails to redeem.
  • Payment routing differs. GovEase lien sales in some states settle through the county office, not GovEase; do not assume the platform collects final funds.
  • Platform rosters change yearly. A county on GovEase this year may move to RealAuction (or self-host) next year. Never rely on a third-party list — verify on the county’s own page each cycle.
  • Surplus on deed sales. When a price bid-up sale exceeds the debt and costs, the overage is surplus-funds held by the county, subject to the state’s claim procedure and post-tyler-v-hennepin-county rules — the platform plays no role in surplus distribution.

▸ For Former Owners — If your property was sold on one of these platforms, the auction vendor does not hold any overbid — the county does. A price bid-up tax-deed sale that exceeds the taxes and costs generates surplus-funds that may belong to you under your state’s procedure and the tyler-v-hennepin-county rule against the government keeping equity beyond the debt. Identify the platform only to find the sale price and the county that holds the funds; the claim is made to the county, on the state’s deadline.
