Investors have a name for the old way of finding vacant homes: driving for dollars. Pick a neighborhood, drive it slowly, and look for the tells -- knee-high grass, a week of flyers wedged in the door, blinds that haven't moved in months. It works, because the signs of a vacant house are physical, and vacancy is one of the strongest signals a seller is motivated. But there's a detail most investors miss: someone else is already driving those same streets, writing down those same signs, and filing the results as public record -- months before most people notice.
The federal government's own working definition is simple: a property is vacant if no one is occupying it. Roughly 14.5 million U.S. homes currently fit that description, though the reasons vary widely by state -- some are seasonal properties sitting empty in the off-season, others are tied up in probate, foreclosure, or an absentee landlord who has simply stopped paying attention. What all of them share, from an investor's perspective, is the same underlying signal: an owner who isn't using the property is often an owner more open to selling it, frequently below market value, before it ever reaches a listing site.
The classic method is exactly as manual as it sounds -- physically scouting target neighborhoods for the visible tells of neglect: overgrown lawns, boarded or covered windows, accumulated mail, no lights on at night. It remains popular because it costs nothing but time and surfaces genuinely off-market opportunities no list will hand you. The tradeoff is just as real: it only covers as much ground as someone can physically drive, one neighborhood at a time, and by definition depends on catching a property in exactly the state of neglect that makes it visible from the street.
Here's what most investors overlook: city code enforcement inspectors are already doing a version of that same drive, every day, as part of their actual job. When a lawn goes unmaintained past a certain point, when junk accumulates in a yard, when a structure shows visible disrepair, it frequently gets logged as a formal complaint or violation -- public record, tied to a specific address, with a filing date. That filing happens whether or not any investor ever drives past the property in person.
A single complaint about an overgrown lawn could mean plenty of things -- a homeowner on vacation, a tenant between mowings. But multiple simultaneous violations on the same address -- overgrowth, junk accumulation, and structural neglect all cited together -- is a genuinely stronger signal, and one that tends to show up specifically on properties nobody is actively maintaining. That combination is exactly the kind of pattern that surfaces in day-to-day code enforcement data, well before a property is formally listed as vacant or distressed anywhere else. To be direct about what this is and isn't: Stamptd doesn't claim to certify that a given property is vacant -- no permit-tracking service can. What it does is track every new code complaint and violation filed daily across its coverage area, so a pattern like that is visible the same day it's filed rather than discovered by chance months later.
The classic tells are an overgrown or unmaintained lawn, boarded or covered windows, mail and flyers piling up at the door, and no lights on at night. No single sign is conclusive on its own, but the more of them show up together at one address, the stronger the signal.
Vacancy often signals a motivated seller -- financial stress, an absentee landlord who has burned out on renting, or a property tied up in probate or foreclosure. Investors who can reach these owners early sometimes strike deals before the property ever reaches public listing sites.
It's a real, practical proxy signal, not a certified determination. Multiple simultaneous violations at one address -- especially property-maintenance issues like overgrowth or junk accumulation -- are a pattern that shows up disproportionately on properties nobody is actively maintaining, which is often, though not always, a vacant one.
No, and it doesn't claim to. Stamptd tracks every new building permit and code complaint/violation filed daily across its coverage area -- Atlanta, Gwinnett County, and Cobb County in Georgia, with Tampa, Florida next -- and surfaces that data the same day it's filed. Patterns like repeated property-maintenance violations at one address are visible in that data, but interpreting what they mean for any specific property is still up to the person looking at it.
