Tax Sale

A tax sale is a public auction conducted by a county or municipality to recover delinquent property taxes. Depending on the state, the county sells either a tax lien certificate (the right to collect the delinquent taxes plus interest) or the property itself through a tax deed. For mortgage note investors, tax sales represent one of the most critical risks in the business — because a completed tax sale can extinguish every private lien on the property, including first mortgages and second mortgages, leaving the note holder with a total loss.

Tax Lien Sale vs. Tax Deed Sale

The two primary tax sale structures work differently and carry different implications for note investors:

Some states use a hybrid model — a redeemable tax deed — where the county issues a deed to the buyer, but the original owner retains a limited redemption window.

The Tax Sale Timeline

While specifics vary by jurisdiction, the general progression from delinquency to sale follows a predictable pattern:

1. Taxes become delinquent. The property owner misses the annual or semi-annual payment deadline. Penalties and interest begin accruing immediately.
2. Notice to property owner. The county sends delinquency notices and publishes the property on a list of tax-delinquent parcels.
3. Notice to lien holders. In most states, the county is required to notify recorded lien holders — including mortgage note holders — before the tax sale. This notice is your last-chance warning.
4. Tax sale auction. The county conducts a public auction. In a lien sale state, investors bid on the interest rate (bidding the rate down) or premium. In a deed sale state, investors bid on the purchase price (bidding it up).
5. Redemption period. The property owner — and often recorded lien holders — have a statutory window to pay the delinquent taxes, penalties, interest, and any fees to redeem the property.
6. Tax deed issuance. If no one redeems, the tax sale purchaser receives a tax deed. All prior private liens are extinguished.

Why Tax Sales Are Catastrophic for Note Investors

Tax liens carry super-priority status — they outrank every private lien regardless of recording date. This means:

• A $500 delinquent tax bill can destroy a $50,000 mortgage note investment.
• Both senior and junior private lien holders are wiped equally.
• The property transfers to the tax sale buyer free and clear of all mortgage encumbrances.
• Your promissory note becomes unsecured — the collateral is gone.

This risk is asymmetric: the amount at stake (your entire note investment) is vastly disproportionate to the amount that triggers the loss (a relatively small tax bill).

How to Protect Your Investment

Tax sale losses are entirely preventable. Build these practices into your workflow from day one:

• Check tax status during due diligence. Before bidding on any note, verify the property's tax status through the county tax portal. Look for delinquent balances, sold certificates, and upcoming sale dates.
• Monitor taxes on every asset you own. Ensure your servicer tracks tax status on every loan in your portfolio. On non-performing loans with no escrow payments being collected, nobody is paying the taxes unless you advance the funds.
• Pay delinquent taxes immediately. Advance the funds and add the amount to the borrower's outstanding balance. The cost of a few hundred dollars in tax advances is negligible compared to a total loss.
• Redeem sold certificates. If a tax lien certificate has already been sold, you typically still have a redemption window. Pay the delinquent amount plus the certificate holder's interest and fees to clear the lien.
• Respond to county notices immediately. If you receive a notice of pending tax sale, treat it as your highest-priority action item. The redemption deadline is a hard cutoff.

Tax Sales as an Acquisition Opportunity

While tax sales are a risk to existing note holdings, they can also be a sourcing channel. Some investors attend tax sales specifically to acquire properties or certificates. However, tax sale investing is a fundamentally different business from note investing — you are buying real estate or tax debt, not mortgage notes. The skills, capital requirements, and risk profiles are distinct. Note investors should view tax sales primarily through the lens of portfolio protection rather than acquisition strategy.
