Tax Lien Due Diligence Checklist Before the Auction
Due diligence sounds intimidating. It's not.
It's just a 20-minute checklist you run on every property before bidding. Do it right, and you avoid 95% of the disasters that sink beginners.
Here's the exact routine that works.
Step 1: Verify Property Value (5 Minutes)
Don't trust the county's assessed value. It's often outdated or inflated.
Quick value check:
- Zillow/Redfin: Get ballpark estimate
- County records: Pull recent sales within half a mile
- Google Street View: Does it match the comps?
Rule: Your lien amount should be 50% or less of realistic market value. Ideally 30-40%.
Step 2: Confirm Ownership and Title (5 Minutes)
Check the county property records online:
- Who owns it? (Match name on tax lien list)
- Any recent transfers? (Red flag if it sold recently)
- Mortgages recorded? (You want equity, not overleveraged)
Red flags:
- LLC or corporate ownership (might be abandoned investment property)
- Multiple owners (estate issues, complicated redemptions)
- Recent foreclosure filings (might have other liens)
Step 3: Scan for Deal-Killers (5 Minutes)
These will destroy your profit:
- HOA super-priority liens (check HOA estoppel if it's a condo)
- Environmental issues (former gas stations, dry cleaners, industrial)
- Landlocked parcels (no road access)
- Flood zones (check FEMA maps)
- Code violations or demolition orders (call city hall if property looks sketchy)
Real life: Dave almost bought a $7,500 lien on what looked like a great property. Five-minute Google search revealed it was scheduled for demolition due to structural damage. He walked.
Step 4: Visual Inspection (5 Minutes)
You don't need to visit in person (yet).
- Google Street View: Front of house
- Satellite view: Roof condition, yard, pool
- Neighboring properties: Is this the worst house on a good block or the best house in a terrible area?
Your Due Diligence Checklist
Before every bid:
✓ Market value verified (2-3x lien amount)?
✓ Clean ownership (no red flags)?
✓ No super-priority liens or environmental issues?
✓ Visual inspection looks reasonable?
Four checkmarks? You're good to bid.
