Tax Sale Resources

What Tax Sale Resources does

Tax Sale Resources, LLC is a privately held software and services company founded in 2011 by Brian Seidensticker and headquartered in Hamilton, Montana, operating as a fully remote team across North and South America. The company builds a vertically integrated platform for tax lien and tax deed investors in the United States, anchored by a nationwide research database covering 1.4 million+ yearly liens and 200,000+ yearly deeds across 5,100+ jurisdictions and 8,100+ auctions, with 10+ years of historical data aggregated from 5+ cross-referenced sources. Core products include Research (SaaS subscriptions for property discovery and underwriting), Management (portfolio management with a nationwide redemption engine and custom reporting), Financing (asset-based pre-title capital), Trade (escrow and broker services for portfolio transactions), Tax Sale Overages (curated lead generation), and the Accelerator Program (a vetted membership tier). The platform is built on Ruby on Rails with a React JS frontend, PostgreSQL and MySQL databases, and Elasticsearch for search, with continuous integration, automated code quality checks, and production monitoring.

The business model blends self-serve SaaS subscriptions (Research tiers from $97 to $497+ per month, Management from $1,000+ per month), usage-based financing interest (typically 1% per month on loans of $50,000+), per-lead Overages pricing, and transaction-fee Trade services, supplemented by a 2-tier affiliate program that pays 25% (NTLA-certified) or 15% standard direct commissions plus downline overrides. Distribution combines direct website signups and a $1.99 trial for Research, enterprise demo-led sales for Management and Financing, and community-led growth via the Tax Sale Insider podcast, blog, newsletter, and NTLA event participation. Customer segments span individual hobbyist investors, full-time professionals, private funds (Maritime Land, Low Volatility Tax Lien Fund), regulated banks (Evolve Bank & Trust), title and advisory firms (Investa Services, Jax Advisory), and private lenders (Purestone Loan Services). The company has disclosed no external funding rounds, M&A activity, or regulatory actions, indicating a bootstrapped, founder-owned operating model.

Direct peers

• Bid4Assets: Online auction platform hosting government tax lien and tax deed sales as well as seized-asset auctions. Direct competitor to TSR's Research and Trade offerings, operating a marketplace rather than a subscription data product.
• RealAuction: Auction hosting and bidder-registration platform purpose-built for tax lien and tax deed auctions. Competes directly with TSR for county auction relationships and bidder tooling in overlapping jurisdictions.
• GovDeals: Government-surplus auction marketplace covering tax-defaulted and seized assets for government sellers. Overlaps with TSR's data aggregation and auction coverage, though broader in scope beyond real estate tax sales.
• PropStream: Real estate investor data and lead-generation platform with nationwide property, owner, and distress data. Targets a similar investor persona — including tax sale and wholesale buyers — with comparable subscription tiers and self-serve motion.
• RealtyTrac: Foreclosure and distressed-property data platform covering tax-default and REO inventory. Direct comparison for TSR's research and overage-leads products, anchored in the same distressed-investor buyer profile.

Broad incumbents

• ATTOM Data Solutions: Large-scale property data and analytics provider covering tax, foreclosure, ownership, and parcel data nationwide. Wider scope than TSR but its tax-AVM and distressed datasets compete for budget allocated to TSR Research.
• Auction.com: Leading online real estate auction marketplace covering foreclosure, REO, and bank-owned properties. Overlaps with TSR Trade and Research at the institutional buyer level, though anchored in foreclosure rather than tax-default origin.
• CoreLogic: Enterprise real estate data, analytics, and platform provider whose property and tax datasets could be repackaged for tax sale investors. Operates as a broader incumbent whose vertical products overlap with portions of TSR's data stack.
• Hubzu: Online residential auction platform operated by Altisource serving institutional sellers of distressed properties. Comparable in auction execution mechanics but focused on REO inventory rather than tax-default origination.

Emerging players

• AcreTrader: Online farmland investment and acquisition platform. Comparable buyer profile (vacant-land investors) to TSR's land-deed segment cited in customer testimonials, though operating in agricultural rather than tax-default land.
