How it works

CoStar is where many tax consultants and asset managers find commercial sales and lease comparables. The connection is file-based: your team exports search results from CoStar to Excel under its own subscription, and ATALI ELECTRIC maps the columns into its comparable records. ATALI ELECTRIC does not license, resell or redistribute CoStar data, and uploaded comps stay subject to your CoStar agreement and are stored only in your tenant.

Once mapped, each comparable keeps a CoStar source tag along with its sale type and notes, which feed the arms-length screen before anything enters a grid. Sales comps go into the adjusted sales comparison grid with size, age, condition, location, parking ratio and market conditions adjustments; lease comps support market rent, term and concession assumptions in the income approach.

Data flows

  • Lease comparables InboundLease comp exports supply market rent, lease term and free rent support for the income approach.
  • Property characteristics InboundBuilding area, class, year built and parking from exported property records fill gaps in the county record, with differences flagged for review rather than overwritten.
  • Adjusted sales grid OutboundThe approved grid exports as XLSX or as a binder exhibit, with source tags showing which comparables came from CoStar.
