NYC property intelligence
Know a NYC address
before you sign anything.
Deep intel on any NYC address: building and permit records, 311 calls, violations, flood and environmental risk, schools, walkability, and transit times — from a single address.
Free to start, no credit card required.
Who it's for
One address search, four different jobs
Homebuyers
Vet an address before you make an offer — violations, flood and environmental risk, school quality, and transit, in one place instead of a dozen tabs.
Owners & landlords
Check your own building's record, see what comparable homes actually sold for, and estimate market rent from live nearby listings.
Curious neighbors
Look up any NYC address — the new listing down the block, the building with all the scaffolding, the apartment before you sign a lease.
Agents & brokers
Pull a shareable, data-rich report to build trust with a client or back up a listing price.
