In self-storage investing, knowing how to present an offer range the right way can give you a major edge. This guide breaks down the offer range strategy to help you make stronger self-storage offers, build trust with sellers, and close more deals—with insights straight from our self-storage mentorship program.

Quickly size up a self-storage deal using back-of-the-napkin math. Start with gross income, estimate expenses (30–40% if actuals aren’t available), then subtract to get your Net Operating Income (NOI). Divide the NOI by your target cap rate to estimate value. This fast method helps self-storage investors make smarter decisions on the fly without needing a full spreadsheet—perfect for first looks and quick deal screening.
