Real estate investors and agents navigating the Delaware market in July 2026 found Sussex County to be a hub of significant off-market activity, with nearly half of all home sales closing without ever hitting the Multiple Listing Service.

County Overview
Sussex County, Delaware, recorded a total of 10,348 home sales in July 2026, according to BatchData's On Market vs Off Market Sold Report. A substantial 43.1% of these transactions, totaling 4,461 sales, were classified as off-market. This means these properties were sold privately, often directly between sellers and investors, bypassing the traditional open market. In contrast, on-market sales accounted for 5,887 transactions, representing a 56.9% share of the county's total sales volume for the month.
This notable split underscores the prevalence of private deal flow in Sussex County. The high proportion of off-market sales suggests a robust ecosystem for investor-driven transactions, where properties are sourced and acquired through alternative channels rather than public listings. For investors, this indicates opportunities to find deals that may not be accessible through conventional search methods, requiring strategies such as direct outreach or leveraging private networks. The 4,461 off-market sales represent a significant volume that would otherwise remain hidden from the broader market, offering a distinct advantage to those equipped to identify and execute these transactions.

This dominant share highlights Sussex County's outsized influence on the state's real estate landscape, attracting considerable attention from both traditional buyers and savvy investors.
The county's 43.1% off-market share is particularly telling for investors.
