Tristan Waite and I co-founded Bird Dog Recon in 2025, and ReignOverTech built it. It finds off-market property for flip and wholesale buyers in Los Angeles County: houses worth a call before they are ever listed.
The whole product sits on one rule. Look at everything for free, and pay only for the parcels that earn it.
The expensive way to find deals
Commercial property data is paid for by the lookup: owner contact details, property records and more.
The obvious way to build a deal finder is to buy data on a long list of properties and sort it afterwards. Bird Dog covers roughly 550,000 parcels in the parts of LA County it targets. Buying data on all of them up front spends most of the budget on houses that were never going to be a deal.
Free signals first
So every one of those parcels runs through free public-records signals first: code enforcement cases, fire damage, tax-defaulted auction lists and more. Each one is a sign an owner may have a reason to sell.
A parcel with none of them costs nothing and stays out of the way. A parcel that surfaces lands on the buyer's ranked worklist, with a map, filters and saved sorts. Owner contact details are pulled only then, and only when the buyer asks for them.
The money follows the signals instead of the other way around.
Caps that refuse
Every paid lookup runs through a spend ledger with hard caps. A lookup that would cross a cap does not run.
A warning that arrives after the money is spent is a report, not a control. A cap that refuses means a busy week can never turn into a surprise bill.
Ranked on the downside
Valuations come from sold comps, and deals are ranked on their downside, not just their best case.
A flip that looks great at its best price and loses money at a realistic one is not a good deal. Ranking on the downside pushes those to the bottom of the list before anyone spends an afternoon on them.
What stays out of the ranking
A Fair Housing guard keeps protected-class data out of the ranking. The worklist ranks a property on its records and its numbers, never on who lives there.
That was not up for debate. A ranking that can see protected-class data can learn to lean on it, and nobody would notice until it had.
What this rules out
Screening on public records has a blind spot, and it is worth saying plainly. An owner who wants to sell but has no code case, no damage and no tax trouble leaves no trace in the free signals, so that parcel does not surface.
We accepted that. A short list where every row has a reason beats a long one that has to be paid for row by row. The data refreshes weekly and is backed up nightly, so the list keeps up as new records land.
Why this matters past real estate
The pattern is not special to property. Any product that pays per lookup, per call or per record has the same choice: spend first and sort later, or screen on what is free and spend where it counts. We build the second kind, with the cap enforced by the software rather than by someone remembering to check.
