Just ask for a CMA, a pre-pitch brief, or outreach to owners who are likely to sell.\n\nWith Marketproof, ChatGPT can:\n- Run a CMA: pull a building's profile, sales history and closed comps, check current supply, and recommend a list price\n- Analyze sales, contract activity and inventory trends by neighborhood, borough or building\n- Track the market: new listings, price cuts, days on market, and listings that expired unsold\n- Find owners to reach: long-time and absentee owners, pied-\u00e0-terre owners, expiring tax abatements, tax liens and lis pendens, plus likely-to-sell scores on request\n- Check DOB and HPD violations, 311 complaints and building permits before a pitch or a deal\n- Find the brokers and agents active in a building or neighborhood, and look up agent licenses\n\nCoverage: all five boroughs of New York City.\n\nRequires a Marketproof account. When you connect, you sign in and choose which Marketproof workspace ChatGPT uses.\n\nMarketproof capabilities are read-only: they look up data and don't change anything.",
