Short answer

AI for commercial real estate investors is an agent that reads a property's data room and underwrites it: lease abstracts, the rent roll tie-out, the pro forma and the diligence log. On an illustrative industrial park asked at $48.0 million, Compound puts in-place NOI at $2.55 million against the seller's $2.88 million and bids $46.4 million.

Compound works from the documents a commercial real estate buyer receives: the offering memorandum (OM), the leases and amendments, the rent roll, the monthly T12, the general ledger, the appraisal and the third-party reports. Every figure it extracts cites the lease page or report it came from, and the underwriting downloads as an Excel workbook with live formulas. The three worked examples below run one acquisition: Cedar Fork Commerce Park, an illustrative 248,400 square foot industrial park asked at $48.0 million, a 6.00% cap rate on the seller’s NOI.

Rent roll analysis and AI lease abstraction

Compound abstracts every lease and ties each row of the seller’s rent roll to its lease, the tenant’s estoppel and the T12. In the AI rent roll analysis, $109.3 thousand a year of base rent has no executed lease behind it, most of it an unsigned extension, which is about $1.8 million of the ask at the OM’s 6.00% cap rate.

Underwriting: the real estate pro forma in Excel

Compound builds the buyer’s pro forma from the OM, the leases, the T12, the appraisal and the property condition assessment, then rebuilds the lines the seller’s numbers get wrong. In the real estate pro forma example, in-place NOI is $2.55 million against the seller’s $2.88 million, a 5.32% cap rate on the ask; the ask returns 7.52% unlevered over ten years, and an 8.0% return needs a $46.4 million price.

Commercial real estate due diligence

Compound runs the diligence period as a log with an owner, a question for the seller and a due date on every open item, across the property condition assessment, the Phase I, title, survey, zoning and the estoppels. The commercial real estate due diligence example finds trailer stalls inside an easement and a storage yard that zoning can take away, and its 52-item log rolls up into 19 questions for the seller.

Why real estate investment firms use Compound

  • Every number traces to the lease. Click a cited cell to open the lease page, estoppel or report it came from; a downloaded workbook keeps each citation as a cell note.
  • The whole data room at once. Drop up to 15,000 files at once into a deal’s agent, and start a task per property or per lease that subagents run in parallel.
  • Your firm’s model. Compound works in your firm’s underwriting and IC templates, keeps their layouts and formulas, and fills them for the new deal.
  • One agent for the deal team. An associate starts the underwriting, a VP comments on a cell and the agent makes the change, and the partner opens the same model.
  • Enterprise security. Compound is SOC 2 Type II, encrypts data with 256-bit AES at rest and in transit, and never trains on customer data.

FAQ

How is AI used in commercial real estate investing?
On the buy side, AI reads the acquisition’s data room and does the underwriting work: lease abstraction, the rent roll tie-out, NOI from the T12, the pro forma and the diligence log. Compound does each step in Excel with live formulas, every figure cited to its source document.
Can AI do lease abstraction?
Compound abstracts each lease into one row per suite: term, rent schedule, recovery structure and caps, renewal and termination rights, TI allowance, free rent and deposit, each cited to its section of the lease. In the rent roll example, the abstract finds an exit right in the largest tenant’s lease that the offering memorandum leaves out.
Can AI underwrite a commercial real estate deal?
Compound underwrites from the documents: NOI from the T12, lease rollover with downtime, free rent, TI and commissions, capex from the property condition assessment, the cap rate, the IRR at the ask and the price that earns the target return. Its real estate modeling covers industrial, office, retail, multifamily, self-storage and hospitality properties.
