Analytics
Chart Builder, Market Dashboard, and map analytics for trends across markets, submarkets, and competitive sets.
View AnalyticsCommercial property data, with the deals attached.
Building size, class, year built, floors, landlord, and parking ratio on millions of US commercial properties, with the leases, sales, and loans on each building resolved to the same record. Reviewed by analysts.
Property records that hold the leases, sales, and loans.
The building is the unit of record. Every comp CompStak holds on a property rolls up to one page, with the building data beside it.
One building, one record, every address variant resolved.
CRE Ontology resolves street addresses, address ranges, and alternate building names to a single property, so two spellings of the same address are one building. Leases, sales, and loans submitted under any of them land on the same page.
Building specs alongside the rent roll.
Building size, class, year built and renovated, number of floors, lot size, parking ratio, and submarket are recorded on the property. Average lease size and current landlord sit on the same record, so a Class A tower and a Class B loft never share a comp set by accident.
Current landlord, resolved to the entity behind the LLC.
Landlord is recorded as the current owner and resolved to a single entity. Search every building one owner holds in a market, then open the leases, expirations, and loans on each.
A building benchmarked against its competitive set.
Group properties into a portfolio or a competitive set and compare rent, concessions, and term against the market. The set is built from the property records, so the comparison holds as new comps land on those buildings.
