I’m excited to share my Office Development Model in Excel. This pro forma analysis tool comes as I’ve continued to build and share specialty real estate models, tailor-made for specific investment scenarios and property types.
This model is an adaptation of my Industrial Development Model. It’s specifically built to analyze both merchant-build and build-to-core, ground-up office development opportunities. Like the Industrial Development Model, it includes an expandable budgeting and development cash flow module, robust rent roll and operating cash flow module, permanent operating cash flow module, the ability to model complex partnership waterfall structures, and much more.
As with all of our real estate models – and especially those that are newly released – the tool continues to be reviewed and updated regularly, so if you have a feature request or you spot a bug, please let me know and I’ll look to include it in a subsequent version of the model.

Adapting my Industrial Development Model for Office Development
The foundation of this Office Development Model is my Industrial Development Model. In fact, 95% of the inputs, calculation modules, outputs, and features in this model come directly from that model. This is possible because the techniques that are used to model industrial development are largely the same with office development.
Therefore, if you’ve used my Industrial Development Model, you will immediately know how to use this model. No need to watch the tutorial video(s) nor read the written tutorial below. Simply download the model and get started!
If you’re new to A.CRE and/or haven’t used the Industrial Development Model, below you’ll find written instructions for getting started as well as a video walkthrough of the Office Development Model.
Layout of the Office Development Model
So, allow me to walk you through the layout of the Office Development Model. This tool is structured similar to the various models I’ve built over the past few years (e.g. Apartment Development, Self Storage Acquisition, etc). Namely, I use a single Underwriting tab, wherein the vast majority of the inputs are entered and the cash flows are modeled. Outputs/reports are then generated, and displayed on a Summary tab and Annual Cash Flow tab.
While the model contains virtually everything you’d expect from an institutional-quality model, putting all inputs on one Underwriting tab greatly simplifies the user experience. Here are the various worksheets contained within the model:
This model likely still contains errors. If you spot an error, have a feature request, or would like to make a suggestion to improve the model, please let me know.
Version Tab (Visible by default)
The model opens initially to this tab so you can see what changes have been made in the most recent version of the model. On this tab you can also find links to model tutorials, guides, support, and other information.
Underwriting Tab (Visible by default)
The Underwriting tab is where all of your primary inputs are entered. The tab is broken up into six sections, built from top to bottom. The sections can be accessed either by scrolling down to each or using the buttons along the top of the screen. The six sections are ‘Description’, ‘Development’, ‘Operations’, ‘Reversion (Sale)’, ‘Returns’, and ‘Sensitivity’. Inputs are laid out along the left, while outputs/cash flows are calculated along the right.
Summary Tab (Visible by default)
While the return metrics levered IRR, levered EMx, and Development Spread are shown along the top of the Underwriting tab, the bulk of the risk and return metrics are shown/visualized on the Summary tab. The summary tab also includes various charts, a strengths/weaknesses section, a frame to include a picture/map, and a summary of the investment. The Summary tab is meant to be printed, and as such the view mode is set to Print Preview by default.
Annual Cash Flows (Hidden by default)
The Annual Cash Flows tab rolls up the monthly cash flows to annual periods, so you can view high-level cash flows on one page. The report is printable. You can access the report by pressing the ‘Show’ toggle on the Summary tab within the Property Cash Flow section.
Data Tab (Hidden by default)
Some basic backend settings are housed in a Data tab. These settings are related to the s-curve development cash flow forecasting module, date and period headers, data validation lists, and may include other settings as the model evolves.
Walkthrough of the Office Development Model
Below you will find a video for how to use the Office Development Model. This walk through is based on the initial release version of the model. As I continue to improve/update the model, the version you download may vary slightly from the model in this video.
This version of the model is only compatible with Excel 2013, Excel 2016, and Excel 365.
Download the Office Development Model
To make this model accessible to everyone, it is offered on a “Pay What You’re Able” basis with no minimum (enter $0 if you’d like) or maximum (your support helps keep the content coming – typical real estate development models sell for $100 – $300+ per license). Just enter a price together with an email address to send the download link to, and then click ‘Continue’. If you have any questions about our “Pay What You’re Able” program or why we offer our models on this basis, please reach out to either Mike or Spencer.
We regularly update the model (see version notes). Paid contributors to the model receive a new download link via email each time the model is updated.
