Northshore commercial sales by parish, first half of 2026

St. Tammany carries most of the dollar volume, at an average of roughly $1.4 million per transaction against Tangipahoa’s $1.0 million. Tangipahoa holds its own on count, driven by Hammond’s distribution and retail activity at the I-12 and I-55 crossing.

Where the money is going

Covington leads the Northshore in both sales and dollar volume, 35 transactions and $54.2 million, and medical capital is a big reason: a 10,548 SF medical office building on Watercross Pkwy sold for $8.81 million in June 2026, $835 per square foot, and Sabra Health Care, a publicly traded REIT, paid $8.5 million in February for The Trace, an 84,961 SF assisted and independent living facility on Crawford Rd. Mandeville posts the highest average deal size among the four cities at roughly $1.9 million, anchored by the Causeway corridor. Hammond trades on industrial and retail around the I-12 and I-55 interchange and the Southeastern Louisiana University population. Slidell runs on manufacturing and service businesses at the I-10, I-12, and I-59 junction.

What is trading, by property type

Three readings stand out. Retail leads in both count and dollars, 46 sales and $52.9 million, consistent with a market where household growth keeps pulling in operators and net lease investors. Land is 30% of all Northshore transactions, which is what a development pipeline looks like before the buildings show up. And healthcare writes the biggest checks: just 2 sales produced $19.5 million, led by a California healthcare REIT, with more healthcare deals trading after the half closed.

Why the Northshore, and why now

St. Tammany Parish holds roughly 280,000 residents, the fourth most populous parish in Louisiana, and has grown nearly 20% since 2010 per U.S. Census Bureau estimates. Population growth is the upstream input for almost everything in the tables above: rooftops pull retail, payrolls pull office and healthcare, and both pull land development. For an owner, the practical effect is a deeper buyer pool than the Northshore has historically had, including out-of-state REITs, funds, and investors who were not bidding on these assets five years ago.

ELIFIN’s approach to the Northshore

ELIFIN runs the Northshore the way it runs Baton Rouge, New Orleans, and Lafayette: on the Block system. Every commercial property in the coverage area is assigned to a specific agent who is responsible for knowing that block, the owners on it, and the buyers circling it. ELIFIN agents made 58,041 prospecting calls in 2025. When you decide to sell a Covington office building or a Hammond warehouse, the work of finding the buyer started long before the listing.
