Manual lease abstraction and rent roll processing are notorious for slowing down operations, delaying underwriting, and driving up costs. What if you could revolutionize your processes, eliminating hundreds of hours of tedious manual review and instantly feeding clean, structured data into your workflows? This is the promise of AI-powered automation, and in this comprehensive guide, we’ll walk you through how to harness these cutting-edge tools for lease and rent roll automation — all without writing a single line of code.

Kolena’s platform enables real estate professionals to automate complex document workflows with AI agents that transform unstructured data into actionable intelligence in minutes. Whether you manage lease operations, asset management IT, or business analysis, this guide will equip you with the knowledge to accelerate your real estate workflows, reduce costs, and unlock new efficiencies.

Step 1: Understanding the Real Estate Workflow Challenge

Real estate operations often hinge on processing large volumes of documents — leases, rent rolls, amendments, and more. Traditionally, this involves painstaking manual review, which is a significant bottleneck in the workflow. To put this into perspective:

  • Manual lease abstraction can consume between 2 to 8 hours per lease, averaging around 3 to 4 hours.
  • The cost per lease for manual processing can exceed $100, primarily due to the extensive human effort required to analyze complex documents line by line.
  • Finance and real estate teams spend a majority of their time collecting and administering data, with only about 25% of their time dedicated to high-value analysis.

This imbalance means slower underwriting, delayed closings, and rising headcount just to keep pace. The process scales linearly with staffing costs, making it difficult to accelerate without significantly increasing expenses.

Moreover, the data these teams handle often comes in unpredictable formats — from arbitrarily formatted contracts to oddly structured spreadsheets — requiring manual standardization before any meaningful analysis can occur. This adds another layer of delay and inefficiency.

Step 2: Why Traditional Automation Falls Short

Many organizations have tried to tackle these challenges with traditional automation tools such as Optical Character Recognition (OCR), template-based systems, and rule-based bots. However, these solutions have critical limitations:

  • OCR tools extract letters and characters from documents but lack contextual understanding. This often leads to errors when reading complex tables or handwritten notes, necessitating costly human quality assurance.
  • Template automation only covers about 20% of unstructured data, meaning that anything outside predefined formats remains unautomated.
  • Rule-based bots frequently break as document formats or data structures evolve, requiring manual fixes every 9 to 18 months, which burns through budget and slows progress.

Even with these legacy automation methods, brokers report spending up to 48 hours per lease to complete processing, highlighting the persistent inefficiencies.

Step 3: The AI Agent Advantage

The game-changer in real estate workflow automation is the advent of AI agents — intelligent, adaptable systems that leverage advanced AI models to understand and process complex documents with minimal human intervention. Here’s why AI agents stand out:

  • They use natural language instructions instead of rigid code or rules, allowing users to specify exactly what data to extract in plain English (or any language).
  • AI agents can adapt dynamically to new document formats without breaking, eliminating costly bot fix cycles.
  • They combine foundational AI models from industry leaders (like OpenAI and Anthropic) with memory systems that store and reference documents such as leases and rent rolls.
  • Unlike basic chatbots, these agents can call upon specialized tools, including mathematical operations and web search, to conduct complex analyses and calculations.
  • Massive time savings are possible — reductions of 70% to 99% in manual effort per lease have been observed.

For example, an 85-page rent roll document that would take 10 hours to process manually can be completed by an AI agent in less than 5 minutes, achieving over a 99% reduction in processing time.

Step 4: Building Your First Lease Abstraction AI Agent

Now, let’s dive into a practical demonstration of how to create a lease abstraction AI agent using Kolena’s no-code platform. The process is straightforward and designed for users without programming experience.

Did you know? We have a pre-built AI-powered lease abstraction tool and you can use it for free.

4.1 Creating the Agent

Start on the Kalena platform homepage and click Create New Agent. You’ll be prompted to provide natural language instructions describing what you want the agent to do. For lease abstraction, you might enter instructions such as “Draft lease abstractions for commercial real estate.”

4.2 Uploading Example Documents

Next, upload a sample lease document to the platform. It can be any lease, regardless of formatting or complexity — the AI agent will process it without needing predefined templates.

Once uploaded, the platform will process the document behind the scenes, preparing it for extraction tasks.

4.3 Running Extractions

With the lease loaded, you can start asking the agent to extract specific information:

  • Who is the lessee? The agent will identify and extract the lessee’s name, providing a citation of where in the document the information was found.
  • What is the lease type? The AI classifies the lease type (e.g., gross lease) based on contextual understanding.
  • What is the lease term? You can specify the format, such as years and months, and the agent will extract and format this data accordingly.
  • What is the base rent and escalation schedule? The agent can handle complex clauses, including rent abatements and escalations, and provide detailed summaries.

Each extraction includes reasoning and citations, allowing you to verify the results easily.

4.4 Performing Calculations

Beyond simple extraction, the AI agent can perform complex calculations. For example, you can ask it to calculate the total remaining lease obligation from a specified date, factoring in escalations and variable rates over different periods.

This is achieved by routing tasks to the best AI model for mathematical operations, ensuring accuracy and reliability in the results.

4.5 Customizing and Automating

Once you have defined the fields and extraction logic, you only need to set this up once. The agent will automatically apply these instructions to all future documents you upload, instantly producing customized lease abstracts without additional manual work.

You can also adjust instructions or add new extraction fields at any time through a user-friendly interface, no coding required.

Step 5: Automating Rent Roll Extraction with AI Agents

Similar to lease abstraction, rent roll processing can be fully automated using AI agents. Here’s how to get started:

5.1 Defining Instructions for Rent Rolls

Create a rent roll processing agent by providing natural language instructions such as “Extract and analyze tenant unit and payment information from rent roll documents.” The AI will rewrite and optimize these prompts to ensure maximum accuracy.

5.2 Uploading Rent Roll Files

Upload rent roll documents, which can be PDFs, spreadsheets, or other formats. The AI agent can process all supported file types and even combine multiple files in one run.

For example, a rent roll spreadsheet might include tenant names, unit numbers, monthly rents, lease types, square footage, lease start and end dates, escalation percentages, and more.

5.3 Extracting Tenant Details and Analyzing Data

Once the rent roll is ingested, the AI agent can extract detailed tenant information, generate tables summarizing key data, and perform analyses such as:

  • Identifying tenants paying below-market rents by a specified percentage (e.g., 15%).
  • Flagging leases that are expiring soon.
  • Highlighting rent concessions or abatements.
  • Calculating metrics like monthly rent per square foot.

The AI agent can also create executive summaries, providing an at-a-glance overview of the rent roll without manual review.

5.4 Customizing Output Formats

You can tailor the output to match your existing workflows by providing example files or specifying the desired format. The AI agent will replicate the style and structure, making integration with downstream systems seamless.

All processing happens in minutes, dramatically reducing turnaround times and freeing up your team for strategic tasks.

Step 6: Integrating AI Agents into Your Workflow

Automation is most powerful when it fits seamlessly into your existing systems. Kolena’s platform supports “connections” — integrations that link data sources and destinations:

  • Sources: Property management systems, file folders, email inboxes, or any location where lease or rent roll documents appear.
  • Destinations: Project management tools, databases, reporting platforms, or any downstream system that consumes the structured data.

Once configured, new documents dropped into the source locations are automatically processed by the AI agents, and the extracted data or reports are delivered to the specified destinations without manual intervention.

This hands-off process delivers massive time savings and cost reductions by eliminating manual data entry and review.

Step 7: Ensuring Accuracy and Trustworthiness of AI Outputs

One common concern with AI automation is reliability. Kalena addresses this through multiple built-in quality assurance mechanisms:

  • Automatic prompt optimization: The system rewrites your instructions to maximize clarity and effectiveness when communicating with AI models.
  • Citations and reasoning: Every extracted data point includes references to the source document and a transparent explanation of how the AI arrived at the conclusion.
  • Confidence and quality checks: Each result is assigned a confidence level indicating the trustworthiness of the output. Anything below “high” confidence signals the need for closer human review.
  • Feedback loops: You can suggest improvements to the extraction logic through natural language instructions, continuously refining the AI agent’s performance without coding.

Underneath the hood, a task planner selects the best AI models and runs quality assessments at every step, ensuring the system produces accurate and reliable results you can trust.

Step 8: Expanding AI Automation to Other Real Estate Use Cases

While lease abstraction and rent roll processing are critical workflows, AI agents can automate a wide range of real estate document tasks, including:

  • Investment memo creation
  • Financial modeling inputs
  • Regulatory compliance documentation
  • Back-office administrative tasks
  • Contract review and management

The flexibility of AI agents means you can customize them to fit virtually any document workflow, unlocking efficiencies across your entire organization.
