Day 39: How Much Should You Offer? The Storage Valuation Formula Explained (Storage 100)

Welcome to Day 39 of the Storage 100 Series.

In today’s episode, Joe DS from the Storage Mastermind tackles one of the most important questions in real estate investing:

How much should you actually offer on a self-storage deal?

To answer that, we break down the valuation formula step by step so you can confidently make offers — and avoid the biggest mistakes that cause investors to overpay.

In this lesson, you’ll learn:

The simple valuation formula: NOI ÷ Cap Rate = Value

Why sellers’ NOI is almost never your true NOI

Common ways sellers inflate NOI (and how to spot it)

How vacancy, management, taxes, and expenses change value

Why using the wrong Cap Rate can cost you hundreds of thousands

How Cap Rates reflect local risk, not national averages

The power of value-add investing and future NOI

How to create equity by executing a business plan

The 70% Rule for deep value-add deals

Why lowball offers work (and how anchoring bias helps you)

How to use the offer calculator to stay disciplined and unemotional

This entire framework is designed to protect you from overpaying — and from letting emotion drive your decisions. When you stick to the math, you buy right. Every time.
