About DoorProfit

DoorProfit exists to help people make better decisions about where to live, work, and invest — grounded in the same crime data law enforcement agencies use, not marketing spin. Every month, hundreds of thousands of families consider relocation, tenants hunt for apartments, and real estate investors analyze rental-property markets. Historically, getting a clear, address-level picture of neighborhood safety meant hours of scraping municipal websites, parsing city-specific UCR supplements, and triangulating trends across agencies that report data on different schedules and taxonomies.

We replace that hours-long, patchwork research process with an instant, map-based answer for any address in the United States. That answer is built from authoritative public-safety sources, normalized into consistent per-100,000-residents rates, and graded on a single A+ through F scale so a first-time renter and a portfolio landlord can compare two neighborhoods in seconds.

DoorProfit’s crime data is sourced from state and local law enforcement agencies, then cross-referenced against the FBI Uniform Crime Reporting (UCR) program and the National Incident-Based Reporting System (NIBRS), which as of 2021 is the FBI’s primary national crime-reporting standard. Where state UCR supplements publish more granular incident-level data (California’s CA-UCR, Texas UCR via DPS, New York’s DCJS reports), we incorporate those feeds to improve coverage in major metros.

Registered offender information is aggregated in accordance with federal registered-offender registry standards established under the Jacob Wetterling Act (1994), Megan’s Law (1996), and the Adam Walsh Child Protection and Safety Act (2006), with state-level registries maintained by each state’s department of public safety or attorney general’s office.

Safety grades (A+ through F) are calculated by a proprietary algorithm that takes as inputs:

• Overall crime rate per 100,000 residents versus the national average (FBI reports total crime 2,212.8 per 100K, violent crime 380.7 per 100K, property crime 1,832.1 per 100K for the most recent reporting year).
• Violent crime rate (murder, aggravated assault, robbery, rape) weighted at 2× property crime severity.
• Property crime rate (burglary, larceny/theft, motor vehicle theft).
• 12-month trend direction (is the neighborhood improving or declining?).
• Population-weighted percentile ranking among U.S. cities of comparable size.

An A+ grade indicates a crime rate in the bottom 10% nationally for a city’s population tier; an F indicates the top 10%. Grades refresh daily as new incident reports are ingested.

Core tools include:

• Crime Map — interactive heat map with address-level incident breakdowns and A+ to F safety grades.
• Crime Statistics — browsable by city, zip code, and neighborhood with year-over-year comparisons.
• Registered Offender Search — national registry search by address, city, or zip.
• Deal Analyzer — ROI, cap rate, and cash-on-cash modeling with crime data folded into the underwriting.
• AI Expert — chat with an AI that can answer natural-language questions against the crime dataset.

Free searches are available to everyone, with no account required. Creating a free account unlocks additional searches. For unlimited access we offer a monthly subscription at $8 (cancel anytime) that unlocks unlimited address searches, violent-crime alerts, and registered-offender move-in notifications.

DoorProfit publishes crime data under a Fair Housing Act-aware framework: we surface facts about incidents and crime rates, not inferences about the people who live in a neighborhood. Crime statistics are descriptive tools, not predictive ones, and users should consult local law enforcement, real estate professionals, and their own judgment when making relocation or investment decisions. Where incident counts are too low for a reliable rate calculation, we display an explicit “insufficient data” indicator rather than a potentially misleading grade.

We respect user privacy. Registered-offender locations are displayed in accordance with state publication standards and never geocoded more precisely than the registry itself publishes.
