What it shows you

  • SDAT

    Spot the modular home pretending otherwise

    Listings sometimes describe modular or manufactured homes as “single-family.” Curbnote pulls SDAT’s classification field, so you know what you’re touring before you drive 40 minutes.

  • SDAT

    See through cosmetic flips

    A 6-month-old sale at $180k now relisting at $450k? Curbnote shows the price history and time gap so you can decide if it’s added value or fresh paint over old problems.

  • MD iMAP

    Catch the highway nobody mentioned

    “Quiet residential street” — except for the I-95 sound wall 400ft behind the back fence. Curbnote checks proximity to highways, rail lines, and airports.

  • PUBLIC RECORDS

    Read the listing’s history, not just its pitch

    180 days on market. Three price reductions. Relisted under a new MLS number twice. Curbnote surfaces all of it on one screen.

  • FEMA

    Flood zones in plain English

    “Zone AE: high-risk, mandatory flood insurance if mortgaged” — instead of cryptic FEMA codes. Sourced and linked.

  • MD iMAP

    Wetlands and critical area flags

    Maryland’s environmental layers, queried per-property. Know what you’re allowed to build before you fall in love with the lot.

Why Maryland first

I'm buying my first house in Maryland right now. The process is a mess — eight tabs open, public records scattered across SDAT, MERLIN, FEMA, and a different portal for every county. Curbnote started as a tool I built for myself.

Maryland's public records are unusually open and machine-readable, which makes it the right place to start. Once it works here, expansion to Virginia, DC, and beyond is a question of plugging in each state's data sources.
