California buyer opened a $57,000 property tax bill after closing, then learned it wasn't theirs

Opening a surprise bill for $57,000 would rattle almost any homeowner.

For one California buyer, that shock arrived after closing on a Los Angeles-area residence in January — and the charge was ultimately tied to old property taxes they did not owe.

Here's what to know

In a Reddit thread in the r/RealEstateAdvice community, the homeowner said L.A. County sent a notice on September 11 for about $57,000 in delinquent property taxes, even though the purchase had closed with a standard mortgage and taxes paid through escrow.

The buyer wrote, "I'm aware non-supplemental property taxes are tied to the property and not the individual."

That made the notice especially alarming, since the sale had already gone through the normal closing process. After reviewing the paperwork, the buyer found that the closing cost sheet did not list title insurance, even though a preliminary title report existed.

Discussion in the thread largely centered on whether the problem came from the county's records or from something missed during closing, such as title or escrow.

One commenter wrote, "This could have been an error by L.A. County, if they accidentally applied the reassessment to the wrong date…"

In an update on September 14, the original poster wrote, "I spoke with the county assessor and they confirmed that I am not liable to pay these postdated taxes owed. I'm supposed to fill up a form on their website."

One commenter said, "Happened to me too in L.A. in 2026, so it happens."

What can be done?

The first step is not to ignore a notice, even if it appears to be incorrect. Reaching out to the mortgage servicer, title company, escrow company, and county assessor can help determine whether the bill stems from a clerical error, a timing issue, or a legitimate claim that should have been resolved before closing.

It can also help to gather every closing document, including the settlement statement, preliminary title report, tax disclosures, and any proof that property taxes are being paid through escrow. If title insurance was issued, that paperwork may be especially important if a claim needs to be filed.

If a county or servicing office confirms the debt is not yours, ask what form or appeal process is required and keep records of every call and email. If the situation remains unclear, legal advice may be worth considering, especially given the amount involved.

Where can I learn more?

Unexpected bills like this do not stop at one California home sale. Homeowners elsewhere have run into similar disputes with tax offices, HOAs, and utility providers long after they thought the charges were settled.

• In St. Louis County, homeowners faced late fees and double charges despite paying property taxes on time.

• In Georgia, a condo owner was hit with a nearly $3K water bill tied to an HOA dispute.

• In Las Vegas, an HOA tried assigning a $15,000 repair bill after tree damage and plumbing problems.
