Lately, I’ve noticed a lot of “data-driven” talk in Southwest Florida that seems to mirror the research we’ve been publishing for decades. From our specific neighborhood spotlights on Pelican Preserve to our Myth vs. Reality series, it is clear that our work is the roadmap for others in the industry.
Most recently, there has been a lot of chatter about “Shadow Inventory.” While we are always flattered when colleagues adopt our themes, it is important to maintain professional accuracy. In real estate, words have specific meanings. If an agent is using 2010 rhetoric to describe a 2026 problem, they aren’t analyzing—they’re guessing.
1. The Receipts: Shadow vs. Invisible
To understand why your home may not be selling, we have to look at the “receipts” of the last 16 years:
Shadow Inventory (The 2010 Definition): I began writing about Shadow Inventory back in 2010 and distressed market shifts. Technically and historically, this refers to distressed, bank-owned foreclosures. Unless these “new experts” are predicting a massive wave of bank repossessions, they are using the wrong term.
Invisible Inventory (The 2017 Innovation): In 2017, I pioneered the concept of Invisible Listings. These aren’t bank-owned secrets; they are active listings that are technically in the MLS but are effectively “hidden” because they fail to meet the Market of the Moment.
2. The April 5, 2026 Audit: Launching the Invisible Listings Index™
Today, we are officially branding our proprietary calculation: The Invisible Listings Index™ (ILI). Our final Sunday morning audit is in, and the data proves we are in an Invisible Market, not a Shadow one.
The ILI Number: Precisely 17.26% of the current Southwest Florida inventory is “Invisible.” These homes are active but statistically dead because they sit outside our proprietary velocity threshold.
The MSI Floor: Our Market Spread Index (MSI) sits at 5,448, with inventory dropping by another 30 units this week.
The Divergence: While 17.26% of the market stays invisible, the “Visible” market is on fire—evidenced by an 18% surge in pending sales despite 6.64% interest rates.

Technical Note on the ILI: The 17.26% Invisible Listings Index™ is calculated by cross-referencing active days-on-market against our proprietary Absorption Velocity Threshold. This identifies properties that are technically ‘active’ but have effectively decoupled from the current 18% pending sales surge.
The Verdict
You can copy a headline, but you can’t copy 38 years of math. If your property has become “Invisible,” it doesn’t matter how many “Shadows” people talk about—you won’t sell until you reset to the math of the moment.
Don’t let your equity stay invisible. Trust the team that didn’t just join the conversation, but started it.
