Market gauge is calculated using active listings and pending sales from the most recently available reporting period (Mar 2026 - May 2026).

Upper Stewartsville is currently tilted toward sellers, with the market gauge indicating a seller's market. Very limited supply is evident, as there are only 2 active listings and the same number of new listings in the latest rolling three-month period.

Prices have been moving higher, with the median list price around $500,000, up roughly 43% from a year ago in this rolling three-month view. That increase follows earlier periods when homes consistently sold at or above list price, including several quarters where 100% of sales closed above asking.

Listing activity has doubled year over year, with both active and new listings rising from 1 to 2, while pending sales have held steady at 1. In a small, tight market like this, buyers face limited options and fast decisions, while sellers work to price correctly in a rising-price environment, and Agent Pronto can help both buyers and sellers connect with an agent who understands these dynamics.
