Tax Lien Due Diligence Checklist

Never bid blindly. Use this comprehensive checklist to evaluate properties, uncover hidden risks, and protect your capital before the auction.

The Golden Rule of Tax Liens

You are buying the debt attached to the property, not the property itself (yet). However, if the lien doesn't redeem, the property becomes your only recourse. Therefore, you must evaluate the property as if you were buying it today.

1. Property Identification & Basics

Verify the Parcel ID / APN matches the county records exactly.
Confirm the physical address using GIS mapping tools.
Check the property type (Residential, Commercial, Vacant Land, Industrial).
Verify the assessed value via the county property appraiser's website.

2. Property Condition Assessment

View recent satellite imagery (Google Earth) to ensure a structure actually exists.
Check Google Street View for neighborhood condition and obvious structural damage.
Drive by the property if local (do not trespass or disturb occupants).
Check for environmental red flags (gas stations next door, industrial zoning).

3. Title & Lien Search

Check for IRS tax liens (these survive tax foreclosures for 120 days).
Check for municipal/city liens (code violations, weed abatement, water bills).
Verify if the owner is in active bankruptcy (halts all foreclosure actions).
Check for other outstanding tax certificates from previous years.

4. Financial & Risk Analysis

Calculate the Total Investment: Face Value + Expected Premium + Auction Fees.
Ensure the Total Investment is less than 10-15% of the property's market value.
Run the numbers through the Bid Calculator to find your maximum premium.
Determine your exit strategy (Hold for interest, or foreclose and flip/rent).

Frequently Asked Questions

Do I need to hire a title company before bidding?

For standard tax liens, a full title search is usually too expensive to do on every property before the auction. Most investors do preliminary checks via county records (O&E reports) and only pay for a full title search when initiating foreclosure.

What is the biggest mistake in due diligence?

Bidding on "junk" properties. This includes unusable slivers of land, condemned buildings, or properties with massive environmental cleanup costs. Always verify the property has real market value.
