My 3 Biggest Tax Lien Mistakes (And What They Cost Me)

Mistake 1: Ignoring the Title Search

My third purchase taught me a lesson I will never forget. I bought a property in a county I had not researched deeply. The judgment amount was $3,200, the appraised value was $180,000, and I thought I had found a goldmine.

What I missed was a federal IRS lien filed against the owner before the sale. In Texas, a federal tax lien can survive the tax sale and give the IRS its own 120-day right to redeem separately from the owner's redemption right — a different clock, with different rules. I had checked the county tax records but never ran a full title search.

The IRS didn't end up exercising its right, but I spent $800 on a title company and an attorney call to confirm that before I felt safe holding the property. It taught me that the auction list is not the full picture. You need a real title search before you bid, not after.

Mistake 2: Chasing High Appraised Values

Early on, I thought the best purchases were the ones with the biggest gap between the judgment amount and the appraised value. A $200,000 property with a $3,000 judgment looked like a steal. I bought several of these in a county I will not name.

What I learned is that high appraised values in certain counties do not always mean high property quality. Some counties appraise properties at values far above what they would sell for in the open market. The gap between bid and value can be misleading.

More importantly, I learned that properties with a big appraisal-to-tax gap in low-demand areas have lower redemption rates. Owners in those areas are more likely to walk away from the property entirely, which sounds good until you realize you now own a property in an area where nobody wants to buy. A $200,000 appraisal that would actually sell for $60,000 is not a win, redemption premium or not.

Now I focus on properties in the $50,000 to $150,000 range in counties with active real estate markets. The redemption rates are higher, and if I do end up owning the property, I have a better chance of selling it.

Mistake 3: Not Tracking Deadlines

This is the embarrassing one. I owned a property that had been in its redemption window for 14 months. I knew the deadline was coming but I did not have it written down anywhere reliable. I told myself I would check it next month.

The owner redeemed on month 16. I did not notice for three weeks. By the time I contacted the county, the payment had been processed and sitting uncashed, and I nearly missed a stale-check reissue window. It would have cost me the full $1,125 flat premium on that purchase, not a partial amount — Texas doesn't prorate, but a missed pickup can still cost you the whole thing if the county's holding period lapses.

That is the mistake that motivated me to build a proper tracking system. If you are buying more than five properties, you need a system that tells you what is happening without you having to remember. Spreadsheets work. Calendars work. TaxLienSimple works. But nothing works if you do not use it.

I now check my portfolio every Sunday morning. It takes five minutes. I look at which properties are approaching their redemption deadlines, which ones have redeemed, and whether the county's payment matches what I'm owed. Five minutes a week saves me from leaving money on the table.

The Real Cost of Mistakes

Add up my three mistakes. $800 confirming the IRS lien wasn't a problem, plus a property that sat the full 180 days in a slow market before redeeming, plus the scare of a nearly-missed check pickup. Total direct cost: about $800. Plus the opportunity cost of having capital tied up longer than expected.

But here is what I tell new investors. $800 in mistakes on a $40,000 portfolio over two years is a 2% drag. That is not nothing, but it is also not catastrophic. And every mistake taught me something that made my next purchase better.

If you buy your first property today, you will make mistakes. Accept that. The goal is not to avoid every mistake. The goal is to keep mistakes small, learn from them, and build systems that prevent the same mistake twice.

Marcus Field Notes: Systems Beat Discipline

I used to think successful investing was about discipline. Make good choices consistently and you win. Now I think it is about systems. Build systems that make good choices easy and bad choices hard.

Tracking is a system. Research is a system. County selection is a system. When you build a system, you do not have to rely on willpower or memory. The system runs in the background and catches you when you forget.

My system is simple. I research counties during the first week of the month. I buy during the second week. I track every purchase immediately. I review every Sunday. That rhythm took me two years to develop, but it is the reason I have not made a significant mistake since my first year.

Start your system today. Even if it is just a spreadsheet with columns for county, amount, homestead status, and redemption deadline. That spreadsheet is worth more than any investing advice I could give you.
