How to Use Claude AI for Commercial Real Estate Leases

Can you use Claude AI for commercial lease analysis?

77% of lawyers surveyed believe that AI will have a transformational impact on their work within the next five years. Claude AI is a powerful AI tool. Its core design is that of a general-purpose, large language model. It relies on an NLP-powered machine learning model designed to process various types of text. It can quickly summarize and mark up lease documents, allowing CRE professionals to focus more time on strategy and negotiations.

But are there any limitations to Claude AI in commercial real estate lease work? Let's break down Claude AI's capabilities to see what it can and can't do.

Key Features of Claude AI for CRE Professionals

For commercial real estate attorneys and lease administrators, the use of AI agents like Claude AI can be compared to having a paralegal who never sleeps. These tools can provide:

Lease Document Summarization: Capable of reviewing and summarizing lengthy lease agreements, including office leases, retail leases, industrial leases, and ground leases.

Clause and Metadata Extraction: Can identify and extract important lease information, including parties involved, rent escalations, tenant improvement allowances, operating expense provisions, and renewal options.

Document Editing and Markup: Can create new Word documents with tracked changes and edits based on your instructions, allowing for redlining and revision suggestions.

Detailed Guide: Using Claude for Lease Document Analysis

CRE professionals can access Claude AI online. Here's a step-by-step guide on how to utilize this online AI chatbot:

Setup and File Upload

Create an Account: Sign up for Claude AI through the platform's official site.

Upload Documents: Select the "Upload" button on your dashboard. Choose the file(s) (PDFs, DOCX, etc.) and submit them for analysis.

Claude utilizes cloud-based processing to ensure high-speed analysis, which is especially important when handling large volumes of data. However, please note that this approach is subject to a token limit. You may need to split large lease documents or extensive lease portfolios into smaller sections for efficient processing.

Prompting Techniques for Lease Abstraction

Provide clear and precise instructions. For example:

Bad Prompt: "Analyze the lease."

Effective Prompt: "Summarize the following office lease agreement. Focus on the landlord and tenant, base rent and escalations, operating expense provisions, tenant improvement allowance, and renewal options. Provide the summary in a clear and structured format, using bullet points for each section. Make sure that all relevant information is included: names, dates, square footage, and specific clauses related to the lease terms."

The more detailed, the better. This helps Claude improve the accuracy and relevance of the results.

Prompting Techniques for Lease Markup and Redlining

Claude can also assist with reviewing and marking up lease documents:

Markup Prompt Example: "Review this office lease and identify any missing or problematic provisions. Specifically flag: (1) missing force majeure language, (2) ambiguous CAM expense definitions, (3) unclear assignment and subletting terms, (4) tenant-unfavorable indemnification clauses, and (5) any renewal notice deadlines that create risk."

Redline Request Example: "Create a redlined version of this lease that adds a 60-day notice requirement for rent increases, clarifies that operating expenses exclude capital improvements, and adds standard tenant audit rights for expense reconciliations."

Document Creation: Claude can generate a new Word document with your requested changes shown in tracked changes mode, which you can then download and review.

Interpreting Outputs

Say we're using the effective abstraction prompt above. You may receive different outputs or responses for lease queries asked of Claude AI. For instance, when summarizing an office lease agreement, you may get varying versions, such as:

Output A:

Parties Involved

• Landlord: Skyline Office Properties LLC

• Tenant: TechStart Innovations Inc.

• Premises: Suite 1200, 5,000 RSF

Rent Details

• Base Rent Year 1: $30.00/SF ($150,000 annually)

• Escalations: 3% annual increase

• Security Deposit: $12,500

• Lease Commencement: March 1, 2025

• Lease Expiration: February 28, 2030

Operating Expenses

• Tenant's Pro Rata Share: 4.2%

• Base Year: 2025

• Expense Cap: 5% annual increase

Tenant Improvements

• TI Allowance: $25/SF ($125,000 total)

• Landlord Work: Building standard improvements

Renewal Options

• One 5-year option at fair market rent

• Notice required: 12 months prior to expiration

Output B: The office lease is between a landlord and tenant for office space. Rent is approximately $30 per square foot with increases over time. There are expense provisions and improvement allowances, but specific terms vary throughout the document.

Output A is much more structured and precise, including key details such as parties, rent calculations, expense structures, and renewal terms. Output B, on the other hand, lacks clarity and depth.

Refine and test your prompts to determine what works well for you.

Note: Claude AI can provide helpful summaries and markup suggestions. However, always validate its outputs, especially when dealing with complex lease provisions and CRE-specific terms.

Continuous Improvements

Claude learns and adjusts as you refine your prompts. For example, you may begin with prompts like "summarize the lease" and then use more detailed prompts, such as "abstract the lease into a standard format with all critical dates, financial terms, and option deadlines" or "review this tenant lease for missing landlord protections and suggest specific language to add."

Claude AI Cautions and Best Practices for CRE Attorneys

Like any other AI tool, Claude may have certain limitations.

Data Security: When using the public version of Claude AI (claude.ai), your uploaded lease documents and conversations may be used to improve the model. For sensitive lease data and confidential tenant information, CRE professionals should consider:

• Using Claude's API through a private deployment with enterprise data protection agreements

• Ensuring that any Claude implementation includes proper data handling protocols

• Reviewing Anthropic's data usage policies before uploading proprietary lease documents

• Redacting sensitive information (tenant names, financial details) before uploading to public versions

Hallucinations: Claude may sometimes provide inaccurate or confusing outputs due to its learning algorithms. Always fact-check critical lease provisions and financial calculations.

Limited Document Markup Workflow: While Claude can create new Word documents and make edits with tracked changes, the workflow requires multiple steps:

1. Upload your lease document to Claude

2. Request specific edits or redlines

3. Claude generates a new Word document with tracked changes

4. Download the edited document

5. Review and accept/reject changes manually

This process works for individual lease reviews but can become cumbersome when processing multiple versions with third party comments, multiple leases or integrating markup suggestions back into your document management system.

CRE-Specific Terminology: As a general-purpose AI, Claude may not always interpret industry-specific terms like "sales kickout" "rogue tenant violation," or "gross-up provisions" with the nuance required in commercial real estate.

These challenges can be managed with careful oversight. For example, CRE professionals can utilize Claude AI for lease abstraction, review, and document markup. Then, they can cross-reference its outputs with established lease practices and market standards.

Bryckel addresses these limitations with tailored AI features specifically designed for commercial real estate lease workflows. It sets up multiple playbooks aware of different asset contexts, provides streamlined markup capabilities optimized for CRE lease portfolios, completes the workflow from LOI stage to draft lease reviews to a secure repository of hundreds of lease abstracts linked with all real estate documents.
