How to Model a Commercial Lease

Requirements

If you work in real estate investment, asset management, or finance, understanding how to model a commercial lease is an essential skill.

 

This course shows you exactly how to build and analyse commercial lease cash flows in Excel – clearly, logically, and with a structure you can reuse across multiple deals.

 

We’ll cover the full lease lifecycle, from start to expiry (and everything in between). You’ll learn how to handle rent-free periods, lease breaks, rent reviews, voids, reletting assumptions, capital incentives, and stepped rents. You’ll also calculate metrics like WAULT, physical and economic occupancy, net-to-gross ratio, and discounted cash flow.

 

Throughout the course, you’ll be shown not just what to build – but why it matters. You’ll be taught how each element flows through to your cash flow, your valuation, and ultimately your investment decisions.

 

This is a practical, real-world course, based on how leases are actually structured in the market. It’s suitable for:

 

– Analysts building models from scratch

– Asset managers reviewing and adapting models

– Investors and lenders who want to understand the numbers behind the leases

 

By the end of the course, you’ll know how to:

 

– Build a flexible tenancy schedule with multiple lease layers

– Model lease breaks, incentives, and future scenarios

– Analyse how different assumptions affect your cash flow and valuation

– Create a one-page dashboard to summarise key metrics and risks

– Use Excel tools like INDEX, MATCH, SUMIFS, and data tables with confidence

 

You’ll also complete a set of real-world tasks using investment brochures from the market – giving you the chance to practise and reinforce your skills in a low-pressure environment. There’s no grading. This is about building confidence and making you faster, sharper, and more commercially aware.

 

Whether you’re working on office, retail, or mixed-use assets, this course gives you the structure and understanding you need to model commercial leases accurately and efficiently.
