01 — Auction Intelligence

Find the real auction, not a recycled calendar

Every listed auction is labeled by how confirmed it actually is — confirmed date, month-only, statutory window, irregular sale, or not yet announced — with the county or state source it came from.

✓825 jurisdiction profiles with verification methodology and official source links
✓Confirmed / projected / not-announced date labeling on every listing
✓Full auction directory searchable by state, county and sale type
✓Tax sale calendar with .ics / Google / Apple Calendar export
✓7-day and 1-day-before reminders plus daily Deal Radar saved-search checks
✓Redemption-deadline alerts once you hold a certificate

Example: Illinois' scavenger sale schedule is labeled statutory-window rather than a fixed date, because the statute (35 ILCS 200/21-215) sets a window, not a day — a distinction most auction-list sites collapse away.

Calendar reminders on Free. Deal Radar and redemption alerts on Pro and Unlimited.

02 — Property Intelligence

See the property before you risk money on it

299,674 published tax lien, tax deed and foreclosure parcels, each scored with an A–D Research Score built from the fields we actually own — parcel identity, economics, auction timing, ownership signals and data completeness.

✓299,674 published parcels, searchable by state, county, product type, price and sale date
✓A–D Research Score (0–100) with the reasons behind every grade
✓Pre-bid risk warnings: thin value-to-bid spread, unverified availability, stale source data, unmapped parcel, possible heir/estate ownership (detected from an "HEIRS OF" / "ESTATE OF"-pattern match on the owner-of-record name — a text signal, not a verified probate record)
✓Mapped location with a link to confirm boundaries in county GIS
✓Owner phone/email lookup for up to 10 properties/month (Unlimited)
✓PDF export of the full report, CSV export of filtered result sets
✓Property Enrichment Report: owner name and mailing address, a deal snapshot (estimated value, debt, equity), sale and mortgage/lien history, and nearby comparable sales with a computed ARV — exportable as a branded PDF
✓TaxLienSimple Index: every state, county and (in dense metros like Detroit, Philadelphia and Phoenix) city scored 0–100 from statutory terms plus live tracked inventory

Example: a City of St. Louis LRA inventory parcel scores its Research Score live from five components — property, economics, auction, ownership, data — you can see this exact calculation run on the Property Reports page.

Public samples on Free. 25 detailed reports/month on Pro, 100/month on Unlimited. Non-subscribers can also buy a single report for $14 or a 10-property county bundle for $39, no account required.

03 — Bid Preparation

Know your limit before the auction starts

Send any property straight into the Bid Safety Calculator. It sets a comfortable range, a caution range, and a firm walk-away price, then prints one auction-ready packet with the property, score, warnings, source and bid limits.

✓Maximum Bid Calculator with comfortable / caution / walk-away tiers
✓Target-yield and interest-rate calculators for lien states
✓Printable auction-ready bid packet (property, score, warnings, source, limits)
✓Simplified Auction Mode for your phone once bidding starts
✓13-point due-diligence checklist and 52-page playbook
✓Direct handoff from any property report into the calculator — no re-entering data
✓Rehab & Flip Calculator (a second tab alongside the Bid Calculator): total project cost, cash required, projected profit, cash-on-cash ROI and annualized ROI from purchase price, rehab budget and financing terms — comps can feed a computed ARV straight in
✓13 free tools total, no signup required for any of them — including a Quiet Title Cost Calculator (what clearing title on a tax deed costs, by state), a Free Property Score Lookup (check a specific tracked parcel's grade before creating an account), and a Tax Sale Overages Search (verified county surplus-funds records by state, county and claim deadline)

Example: on a $12,000 opening bid against a $48,000 assessed value (a 75% spread), the calculator flags that as strong economics — the same 75% threshold the Research Score uses to avoid a thin-spread warning.

Calculators, including the Rehab & Flip Calculator, are free to use on every plan. The property-to-calculator handoff is Pro and Unlimited.

04 — Portfolio Operations

Track every deal from first look to final result

Move a saved property through seven stages — New, Reviewing, Qualified, No Bid, Bid Submitted, Won, Lost — and a winning bid becomes a tracked certificate automatically, with live accrued interest and redemption-deadline countdowns.

✓Seven-stage deal pipeline from candidate to outcome
✓Live accrued-interest calculation from purchase amount, rate and date
✓Redemption-deadline tracking with a 30-day urgency flag
✓Import existing certificates from a spreadsheet
✓Document and source-link storage per certificate
✓Portfolio totals: accrued earnings and urgent-deadline count at a glance

Example: a certificate purchased for $4,200 at a 9% rate shows its accrued return recalculated live every time you open the dashboard, alongside the days remaining before its redemption deadline.

Track 3 certificates on Free, 25 on Pro, unlimited on Unlimited.

05 — Academy and Intelligence

Learn the mechanics, then keep current on what's changing

A structured Academy walks new investors from choosing a sale to recording a winning investment, backed by sourced state guides and an editorial verification policy that documents corrections instead of silently overwriting them.

✓Academy lessons and a 9-step beginner path — no coaching-sales pitch
✓51 state and DC guides with sourced statutory terms
✓Monthly Auction Radar highlights (Pro); complete Auction Radar with Policy and OTC Watch (Unlimited)
✓Public corrections log and editorial policy
✓Free 51-state comparison dataset (CSV/JSON, CC-BY)
✓County deep-dives inside the member library

Example: TaxLienSimple's corrections log documents that Florida is a lien-certificate state, correcting a commonly repeated mislabeling as a deed state — with the correction dated and left visible, not quietly edited away.

Academy and state guides are free. Auction Radar tiers by Pro/Unlimited.

06 — Professional Data

Pull the data into your own workflow

REST API access to statutory terms, county competition scores and parcel-level inventory, plus bulk exports and licensing for teams that need the full dataset instead of paginated calls.

✓Public GET /api/v1/states and /api/v1/counties endpoints — no key required
✓Keyed GET /api/v1/parcels for parcel-level JSON/CSV (Unlimited)
✓Full technical reference: authentication, rate limits, every field
✓Bulk full-dataset and scoped (state/county) exports
✓Data licensing for redistribution inside your own product
✓Direct county, auction-platform and vendor partnerships

Example: GET /api/v1/counties?state=Texas returns Travis County's live competition_score (64.4, High band) — the same figure documented on the Data API page.

Aggregate endpoints are public. Parcel-level API access is included on Unlimited.

07 — Deal Execution

Reach the owner and track it through to closed

Once a property is on your radar, the Letters & Scripts library and the Outreach Tracker take it from research to an actual outreach attempt — draft it yourself via email, phone and printer, or have TaxLienSimple physically mail the letter for you.

✓13 ready-to-use templates: cold-approach owner outreach, absentee-owner variant, follow-up, a phone script, purchase/assignment contract explainer, assignment-of-contract notice, letter of intent, redemption-rights explainer, notice-of-right-to-redeem starting point, tenant notice and cash-for-keys letter
✓Merge-fields auto-fill from a selected property, plus AI-assisted refine (shorten, warmer tone, reference this property's specifics)
✓Every template carries a clear disclaimer: not legal advice, have it reviewed by a licensed attorney
✓Outreach Tracker: a Kanban board (To Contact → Contacted → Responded → Under Contract → Assigned → Closed, plus Dead/No Interest) with one-click add from any researched property
✓From a card: Email opens a pre-filled draft in your own email client, Print generates a mail-ready PDF letter, Call opens your phone's dialer — all three hand off to your own channel
✓Mail: TaxLienSimple prints and physically mails the letter for you (via Lob) directly from a card, no printer, envelope or stamp required — billed against a monthly letter allowance with pay-as-you-go top-ups

Example: printing a letter for a card pulls the owner's mailing address from that property's already-unlocked enrichment report — if the property hasn't been unlocked yet, Print prompts you to enrich it first instead of printing a blank letter.

The library and the tracker board are free to use on every plan, including Free. Print requires the same base property unlock as the enrichment report (Pro and Unlimited). Email, Call and Mail require the owner-contact unlock (Unlimited only).

We do not sell the headline rate. We show the work behind it.

Our profiles distinguish statutory maximums from realistic retail outcomes and document sources, competition, process risk, redemption rules, and verification dates. TaxLienSimple provides information and operational tools—not legal, tax, or investment advice. Always confirm auction information with the administering authority.
