Marketproof
ChatGPT pluginNYC real estate data and CMAs
Marketproof brings New York City real estate data into ChatGPT. Just ask for a CMA, a pre-pitch brief, or outreach to owners who are likely to sell.
With Marketproof, ChatGPT can:
- Run a CMA: pull a building's profile, sales history and closed comps, check current supply, and recommend a list price
- Analyze sales, contract activity and inventory trends by neighborhood, borough or building
- Track the market: new listings, price cuts, days on market, and listings that expired unsold
- Find owners to reach: long-time and absentee owners, pied-à-terre owners, expiring tax abatements, tax liens and lis pendens, plus likely-to-sell scores on request
- Check DOB and HPD violations, 311 complaints and building permits before a pitch or a deal
- Find the brokers and agents active in a building or neighborhood, and look up agent licenses
Coverage: all five boroughs of New York City.
Requires a Marketproof account. When you connect, you sign in and choose which Marketproof workspace ChatGPT uses.
Marketproof capabilities are read-only: they look up data and don't change anything.
