Introducing the Flywheel Equity Self Storage Deal Analyzer

A Simple but Powerful Deal Analyzer Spreadsheet for Underwriting Self Storage Real Estate



Flywheel Equity is happy to provide the self storage underwriting spreadsheet (SSDA for short) it uses  to underwrite hundreds of self storage deals. The SSDA is available for free to all operators and investors.

The SSDA is Opinionated

While we believe the SSDA is powerful and useful for the majority of use cases, it was developed with a very specific investment and usability philosophy. Those include:

  • Simplicity: There should be no tab-switching in the course of underwriting. All information should be logically presented in one main screen.
  • P&L is truth: Underwriting isn't about hitting high-level numbers, it's about presenting a realistic and operationally sound P&L statement over the life of the deal. As such, the P&L is the most important deliverable and should front and center at all times.
  • IRR is folly: Perhaps the most controversial of our underwriting opinions is that any metrics based on unknowable assumptions (such as exit cap rates) should not be used when evaluating a deal. As such, the only summary investment metrics included are the stabilized return on cost and debt yields.
  • Monochrome: There are no green/red color indicators for go/no-go hurdles or criteria. Humans are illogically influenced by visual indicators and underwriting is much more nuanced than that.
  • Cloud-based: We don't do Excel here at Flywheel Equity. The SSDA is a Google Sheet and will always be cloud-native (if you are committed to Excel, please inquire for our commercial services which can accommodate an Excel-based product).

How to Use the SSDA to Underwrite a Self Storage Deal

If these opinions are more or less inline with yours, I encourage you to give the SSDA a try. I've put together a short video here briefly covering the main points of the SSDA, the philosophy behind it, and how to underwrite a deal using it:
