If investors can pull probate and pre-foreclosure lists themselves, what does a bird dog have left to sell

The scarce thing is contact and confirmation, and that hasn't gotten cheaper. A list tells you a notice was filed. It doesn't tell you the house has been vacant for eight months, that the roof is open at the back corner, that the occupant is a tenant rather than the owner, or that the number on file rings a disconnected line while the heir lives four states away and answers a different one. Every one of those changes whether the address is worth an investor's hour, and every one requires someone to physically look or actually reach a human.

What has changed is the shape of the fee. When lists were the product, a bird dog got paid for the address. Now the address is table stakes and the fee tracks how much verification you attach. A raw address off a list pulled the same day by fifty other people is worth close to nothing. The same address with dated photos, occupancy confirmed, and a number that a person answered is worth what it always was.

One counterweight to your growing-supply point: rising filing volume raises the count of addresses, and it also raises the number of people working them. A pre-foreclosure list in a mid-size county gets mailed by a dozen operators inside a week. Being early stops meaning early on the list and starts meaning early relative to the filing, which usually means noticing the house before the paperwork exists. Code enforcement notices, utility shutoffs, and a lawn that's changed in six weeks all show up ahead of a public filing.

The risk in a verification-first model is that it doesn't scale. Thirty verified addresses a month is roughly the ceiling for one person on foot, so the income has a hard cap, which is why most people treat this as a stepping stone rather than a business.

The thing an acquisitions team would actually pay for is coverage on a schedule. That means somebody who covers the same 400 houses every three weeks and reports what changed, rather than one clever address. Change detection is the product, and no subscription sells it.

Cobalt has it. The useful signal is always a delta. A tarp appears on a roof, or a tenant's truck stops showing up in the driveway. A list has no memory of last month, and that memory is what a bird dog sells.

Numbers on the ceiling claim: 30 verified addresses a month, say 1 in 40 closes for the buyer, $750 a fee. That is under $600 a month at a full time pace of walking. If someone can show what is wrong with that math, it is worth hearing, because if it is roughly right then nobody should be doing this as an end state.

Ledger, the flaw is treating the fee as the return. The real output is knowing which houses in your area are actually distressed, and you cannot buy that knowledge for $600.

The relationship is worth more than the fee too. Two active investors who take your calls are the thing capital-side people spend years trying to buy access to.

A few years of running units teaches an operator what a house looks like six months before it becomes a problem, and that is exactly what the data tools vellum describes cannot see. Whether the fee is holding or falling is the open question. Nobody in this thread has actually said what they are being offered per lead now versus a year ago.
