22 Days on Market: How Sumner Healy Built the Ultimate Land Disposition System
Sumner Healy describes how his platform Land Insights functions as an all-in-one operating system for land investing, covering everything from market selection and lead scoring to disposition and listing optimization. He highlights that his business averages just 21.75 days on market for new inventory, attributing this to AI-driven tools including a new disposition platform called DealFlow and an instant drone photo generator. He argues that the right combination of data tools and skill creates a compounding advantage that would be impossible to replicate manually.
Summary
In this interview, Sumner Healy walks through how Land Insights has become the central operating system for his land investing business, replacing a fragmented stack of multiple expensive subscriptions with a single unified platform. He frames the core value proposition as giving skilled operators access to better data and automation than they could achieve manually, and credits the platform directly for his business results.
Healy breaks down the full workflow the platform supports: market selection, data aggregation, AI-powered lead scoring to filter out undesirable properties, front-end pricing tools, and a proprietary metric called the Genie Index that tracks price homogeneity across counties and zip codes nationwide. On the underwriting side, he notes that his team's first-pass comping time dropped from roughly 15 minutes to about 5 minutes per deal — a 66% reduction — and that new employees with no land experience are now comping at his level within weeks, eliminating him as a bottleneck.
For disposition, Healy says his average days on market for inventory acquired in 2025 and early 2026 is 21.75 days, with some properties receiving multiple offers within 48 hours. He attributes this to three marketing levers: the cover photo, the sequence of the first five photos on Zillow, and listing copy designed to proactively address buyer objections. He criticizes the typical land listing as having repetitive drone angles, poorly framed iPhone photos, and no strategic copy.
The interview then covers DealFlow, a new AI-driven disposition management tool built into Land Insights and free for Pro subscribers. DealFlow tracks daily Zillow views and saves rather than the platform's rolling 30-day default, allowing real-time feedback on pricing and photo changes. It tells users what their cover photo should look like, how to sequence photos, how to write copy, when to reprice, when to relist, and flags stragglers across an entire inventory. Healy says in its first 9 days, $51 million in land moved through the platform with over $20 million in profit.
Finally, Healy reveals that Land Insights now generates instant AI-rendered drone-style photos for $25 each in about 30 minutes, replacing traditional drone pilots who cost $300–$500 and introduced scheduling delays and inconsistent quality. He emphasizes that listings need to launch in their most optimal form to capitalize on the MLS's natural 7-day algorithmic surge for new listings, and that DealFlow flags corrections needed on day one to maximize that window.
Key Insights
- Healy claims his team reduced first-pass comping time from ~15 minutes to ~5 minutes per deal using Land Insights' comping tool, and that new employees with no land experience reach his underwriting level within a couple of weeks — eliminating him as the bottleneck on deal approvals.
- Healy reports that his average days on market for new inventory acquired in 2025 and early 2026 is 21.75 days, with some properties receiving six offers within 48 hours, in what he describes as one of the worst disposition environments he's seen.
- Healy argues that the first five photos on a Zillow listing must tell the full story of a property because those are the only ones shown before a user has to click through, and that most land listings waste those slots with repetitive drone angles or low-quality iPhone photos.
- Healy states that DealFlow tracked $51 million of land with over $20 million in profit flowing through the platform in its first 9 days after launch, and predicts a billion dollars of land will move through it within the next year.
- Healy reveals Land Insights built a patented system that generates AI drone-style photos for $25 in about 30 minutes, replacing traditional drone pilots costing $300–$500 who introduced scheduling delays that caused sellers to miss the MLS's natural 7-day algorithmic surge for new listings.
