How many parcels of land go to probate or tax auction in the US each year?

I get asked some version of this question every week — by operators sizing their TAM, by investors trying to understand where the distressed deal flow actually comes from, and by the occasional reporter who hasn’t bothered to check whether anyone actually knows the answer. The honest answer is that nobody knows the exact figure, because no federal agency tracks vacant-land transfers separately. But the math is straightforward enough to model from public data, and for an operator’s purposes the order of magnitude matters more than the second decimal place.

This is the article I send people now. Save it, share it, argue with the assumptions in the sources section. If you have a better dataset on any of these inputs, send it to admin@roostercapital.land and we’ll update the methodology when new data comes in.

The bottom line

The two channels overlap by roughly 10–15% (heir inherits, doesn’t pay the tax bill, the parcel cycles to auction 24–36 months later). That overlap is already netted out of the combined range above.

How the probate math works

The CDC’s National Center for Health Statistics reported 3.07 million deaths in the United States in 2024 — the most recent year with finalized data. From that anchor:

• Homeownership. The Federal Reserve and US Census Bureau put US homeownership at roughly 65%. That implies about 2.0 million decedents per year owned at least some real estate at the time of death.
• Probate avoidance. A meaningful share of those estates skip probate entirely — through revocable trusts, joint tenancy with right of survivorship, transfer-on-death deeds, or beneficiary designations on titled assets. Estate-planning industry surveys (American Bar Association, AARP) put the avoidance rate at 50–70%, with the higher end concentrated in coastal states where trust planning is more common.
• Net probate volume with real property. That leaves roughly 1.0 to 1.4 million probate estates per year that include at least one piece of real property requiring probate administration.
• Vacant-land share. Vacant and non-improved land is roughly 15–20% of the parcel mix inside those estates — higher in rural states like Texas, Arizona, and New Mexico, where second-tier or undeveloped acreage is a common inheritance asset.

That gives us 150,000 to 300,000 raw land parcels moving through US probate courts every year.

The total probate case count is actually larger — the National Center for State Courts reported approximately 2.6 million probate-adjacent filings in 2023 — but that figure includes guardianships, conservatorships, and contested-estate filings that don’t involve real property transfer. The 1.0–1.4M figure above is the subset that does.

How the tax-auction math works

The National Tax Lien Association’s 2024 report puts the number of properties entering some stage of tax delinquency foreclosure at approximately 1.2 million per year. That number is the headline figure people cite, but it’s a pipeline figure, not an outcome figure. It conflates a few different stages:

• Pre-foreclosure / lien only. Many counties post a tax lien long before the property ever reaches an auction block.
• Redemption. Roughly 70% of delinquent property owners pay before the auction date, based on Pew Charitable Trusts analysis of Philadelphia and a handful of other major-county datasets. Redemption rates vary enormously by state — Florida’s runs much higher than Michigan’s, for example.
• Actual transfer at sale. When you back out the redemptions and the liens that never reach sale, somewhere between 150,000 and 250,000 parcels actually transfer at tax sale every year.

Vacant and abandoned land is overrepresented in this channel because absentee owners are the operators most likely to forget, ignore, or walk away from a tax bill on a property they never see. Industry analysis from the Lincoln Institute of Land Policy and county-level audits in Detroit, Cleveland, and Philadelphia put the vacant-land share of tax-delinquent properties at 40–60%.

That gives us 75,000 to 150,000 raw land parcels at tax sale annually.

Why operators should care

If you’re operating in this business, that ~330,000-a-year / 904-a-day figure is your distressed-source TAM ceiling. A few honest implications:

The market is bigger than the operators in it. Even if every active land flipper in the country sourced 5–10% of their pipeline from probate or tax auction lists, that’s 16,500 to 33,000 deals a year — and the public lists for both channels have far more inventory than that already.

Distribution beats sourcing. The constraint in land flipping isn’t finding parcels that are technically distressed. It’s reaching the heir or the absent owner before the courthouse does, and before another operator does. The operators who win at this aren’t running better acquisition lists; they’re running better outreach systems.

Geography concentrates the math. Texas has 254 counties running monthly tax sales. Georgia has 159. Florida and Mississippi run heavy volume. The Mountain West — Arizona, New Mexico, Colorado, Nevada — drives a disproportionate share of the vacant-land subset specifically, because that’s where most of the country’s undeveloped inheritance acreage actually sits. If you’re an operator and you’re trying to scale, picking one or two of those states and going deep beats spreading across ten.

Probate sources are slower but cleaner. Tax auction lists move fast and are mostly public; probate moves at the speed of an attorney and the lists are harder to assemble, but the seller is usually more motivated when you do reach them. Most operators we fund work both channels and lean heavier on probate as their pipeline matures.

Land funding is the boring middle of real estate — and that’s exactly why it works. The distressed pipeline doesn’t go away. Someone’s funding the operators who reach those landowners. Might as well be the one who actually partners with them. — Drew Haney, REtipster Ep. 253, Jan 2026

Caveats — what this estimate is not

This is a derived number, not a measured number. Four things to keep in mind when you cite it:

• No federal agency tracks vacant-land parcel transfers separately. The 1.2 million NTLA figure conflates lien sales, deed sales, and pre-foreclosure stages. The 3.07 million CDC death figure is precise; everything downstream of it is modeled.
• The vacant-land share is the softest input. Bowman & Pagano’s widely-cited vacant-land survey found 16.7% of urban land is vacant — rural ratios are higher but less well studied. We use 15–20% for probate and 40–60% for tax delinquency. Both are defensible from the available literature, but neither is a measured federal census.
• State variation is enormous. Texas alone runs monthly tax auctions in 254 counties; some states only run annual sales; some run hybrid lien/deed systems with very different transfer mechanics. Aggregating to a national number washes out that variation.
• Same parcel can appear in both buckets. When an heir inherits a property and then fails to pay the property tax, that single parcel passes through both probate and tax auction over a 24–36 month window. Our combined range nets out an estimated 10–15% overlap between the two channels.
