About Commercial Lease Cost (Editorial & Methodology)

Commercialleasecost.com is a tenant-side commercial real-estate research and tools site. We model the all-in cost of commercial leases (base rent + NNN + CAM + escalations + TI + free rent + broker fees) across 25 US metros and three lease structures. Every market number we publish is sourced from a primary brokerage report or government dataset and verified quarterly.

What we do

• Build the commercial lease cost calculator that models total cost of occupancy across NNN, modified gross, and full-service gross structures
• Publish per-metro market reports for 25 top US metros, refreshed quarterly from CBRE, JLL, Cushman & Wakefield, Newmark, Colliers, CommercialEdge, CommercialCafe, Prologis Q1 2026 reports
• Publish editorial guides on lease negotiation, CAM reconciliation, TI, escalation, broker fees, and lease structure
• Operate the AI Negotiation Coach, a Gemini-2.5-Flash-powered tool that generates counter-offer language for tenant-proposed terms

Who we side with

Tenants. Always. We are not a listing site, not a landlord rep firm, not a coworking marketplace. Every page is written for the tenant’s interest. When the math says the tenant should walk, we say walk. When the market is soft, we tell tenants to push hard. When the market is tight, we tell them when to fold.

Author

Aissam Baidi is the founder and primary author. Compiles commercial rent + NNN data from CompStak, CoStar, and direct broker reports across 25 US metros.

Reviewer

A credentialed CCIM-designated reviewer signoff is required and pending before AdSense application. We will publish the reviewer’s name, credential, and last-review date when finalized.

Network context

Commercialleasecost.com is part of the Soft Crown network of commercial real-estate and small-business research tools. Each site in the network operates independently with its own editorial standards. We don’t cross-promote or cross-link to other network sites for footprint reasons.

Not financial or legal advice. Estimates based on publicly available market data and broker reports. Commercial real-estate is highly local and deal-specific. Consult a licensed commercial real-estate broker and a real-estate attorney before signing any lease.
