Self-Storage Real Estate

A Practitioner's Guide to Street Rate, In-Place Rate, Length of Stay and the Rent Roll That Has No Leases

Every other asset class hands you a lease. A self-storage store hands you 470 customers who can cancel this month. The price on the website is £32.65/sq ft. The rent roll collects £35.93/sq ft. That gap — 10.0 per cent — is not a market fact: it is an operating record, and resetting every customer to the website price removes 17.7 per cent of the asking price.

These are the workbooks the book was written from. Every figure the book prints is reproduced by a live formula, and the model workbook ends with a sheet that compares the two line by line.

How to use them

Blue on pale blue is an input you may edit. A yellow fill is the carrying assumption of the sheet — the one to argue about first. Black is a formula. Nothing is locked, protected or watermarked. There are no macros and no external links.

The model workbook ends with a sheet called Checks: the figure as the book prints it, the figure the workbook computes, the variance and a status. If a line ever reads “to check”, the workbook and the book have drifted apart — and the workbook is right.

Three numbers to compute on your own store

  1. Length of stay, in months. Not churn, not occupancy — the expected months an arriving customer stays. Here it is 13.8 months. Almost everything else is a function of it, and most operators do not report it.
  2. The move-in flow your occupancy requires. Occupancy equals move-ins times length of stay. Holding 79.6 per cent here takes 34.0 new customers every month, indefinitely. Ask any lease-up plan for that number before you ask it anything else.
  3. What you spend to stand still. Discount plus marketing, divided by nothing — just the annual total. Here it is £109,074, or 11.0 per cent of the rent roll, purely to replace the customers who leave. That is the recurring cost of an income with no contract behind it.

One warning, because it decides the answer

The increase applied to existing customers is what manufactures the rent roll, and how far to push it turns on a number nobody publishes: how sharply customers respond. The second workbook exists to measure it rather than assume it. What the book can say is which part of the conclusion survives not knowing: the optimum ranges from 10.1 per cent to 17.4 per cent across plausible beliefs — too wide to act on as a figure — but under every one of them it lies above the 8.2 per cent this store applies. The magnitude does not survive. The direction does.
