How to Make Money with Tax Sale Overages: How the Business Actually Works

Updated September 2026. General education, not legal advice. Results vary and no income is guaranteed.

When a property is sold at a tax sale or a foreclosure auction for more than what was owed, the difference does not vanish. It sits with the county, the trustee or the court as an overage — also called surplus funds or excess proceeds — and by law it belongs to the former owner or their heirs. Most of them never find out. That gap is where the tax sale overage business lives: a private researcher finds the record, finds the person, and helps them file the claim in exchange for a contingency fee that is paid only after the county pays them.

This article explains how that work actually earns a fee, step by step, and what it costs in time and money to get started. It is written for someone who has heard the pitch and wants the process instead.

Where the money comes from

An overage is created by simple arithmetic. A $10,000 delinquent tax bill, a $100,000 auction sale, and $90,000 left over after the county takes what it is owed. That $90,000 is the overage, and it is held for the person who lost the property, not for the county.

Three kinds of sale produce them, and each has its own rules:

• Tax-defaulted property sales. In California, Revenue and Taxation Code section 4675 governs who may claim excess proceeds and ties the ordinary one-year filing window to the recording of the tax collector's deed. Counties such as Los Angeles and Fresno publish the lists and claim instructions themselves.
• Tax deed sales. Florida's section 197.582 sets out how the clerk distributes surplus after a tax deed sale, and clerks such as Sarasota County explain the claim process in plain language.
• Mortgage foreclosure sales. Here the trustee or the court holds the surplus, not the tax collector, and the procedure is different again. Our lesson on tax liens, tax deeds and foreclosure auctions walks through how to tell the three apart before you open a file.

Identifying which kind of sale you are looking at is the first thing that separates a workable case from a wasted week. Deadlines, forms and the office that holds the money all depend on it.

How you actually get paid

You are not paid for knowing that the money exists. You are paid for the legwork: pulling the record, confirming the balance and the deadline, locating a person the county could not reach, and assembling a claim packet that gets approved the first time.

The instrument is a written contingency fee agreement. The former owner agrees that if the claim is paid, you receive an agreed percentage, and if it is not paid, you receive nothing. Three rules keep this honest and, in many places, legal:

• The owner can always file for free. California's section 4675(c) requires anyone acting on a claimant's behalf to prove that the claimant was told the amount, the source, and their right to file at no cost. Say it in your first letter regardless of the state.
• Fee rules vary by state. Some states cap what a non-attorney may charge, some require a licence or registration, and some do not allow a non-attorney to represent a claimant at all. Confirm the current rules for a state before you send a single letter there, and use a qualified attorney where the law calls for one.
• The fee is paid after the owner is paid. Money flows from the county to the claimant, then from the claimant to you under the agreement. A structure that asks the owner for money up front is a different business, and not this one.

The five steps, in the order you will do them

1. Find

Overage lists are public records, but they are scattered across treasurer, tax collector and clerk websites, and an auction calendar is not a surplus report. Our lesson on how to find overage lists shows the search patterns that work, using the California State Controller's county referral page and Florida clerk sites as worked examples. Preserve the source, its date and the exact URL before you sort anything.

2. Verify

A large number on a spreadsheet is a lead, not a case. Confirm the sale closed, the current balance, whether a claim has already been filed, whether liens or junior lienholders have priority, and when the filing window closes. A list can be accurate for its publication date and describe money that has already been paid out.

3. Locate and contact

The county typically mails one notice to the last known address, which is often the property that was just sold. Your job is to find the person, and then write to a stranger in a way that does not read like the scam they are expecting. Identify your private business, state the source of the funds, give them a way to verify it independently, and tell them they can file themselves. Similar names and a current address are leads to confirm, not proof of identity.

4. Claim

The paperwork is the part nobody teaches, and it is where most beginners stall. The documents go in a specific order: the fee agreement, a limited power of attorney or the county's authorised-agent form, the county's claim form, a notarised affidavit, and proof of identity and ownership. Trusts, estates and deceased owners add authority documents. Build the checklist from the county's current instructions, not from a template you found last year, and keep proof of delivery. Our overage recovery process lesson covers each stage with a worked Sarasota County example.

5. Get paid

The county reviews the packet, may ask for more evidence, and eventually approves or denies the claim. Approval releases the funds to the claimant; your fee follows under the agreement. Mark a file "submitted" when it is submitted and "approved" only when it is approved.

What it costs to start

The overhead is low compared with most businesses, but it is not zero. You need a computer, a phone, an internet connection and a system for tracking research and outreach. Real costs show up as record-access fees, postage, notarisation, business registration, and any state-specific licensing. Legal advice for contested or unusual claims is a cost worth budgeting for rather than avoiding.

How long it takes

Finding and contacting potential claimants can happen within your first few weeks. Closing a claim usually takes months, because county processing times, document requests and claimant response times are outside your control. Overage recovery is slow, careful work. Anyone describing it as fast income is describing something else.

Mistakes that lose claims

• Working from a stale list without checking whether the funds are still there.
• Treating a matching name as proof of identity or entitlement.
• Promising a claimant certainty about an unresolved payment.
• Missing the statutory deadline because the file was measured from the wrong date.
• Sending a claim without the authority documents a trust or estate requires.
• Failing to keep the signed packet, delivery evidence and every county reply.
