Security Service Federal Credit Union has purchased the 24-acre NuStar Energy headquarters property in San Antonio. The 319,000-square-foot facility, located at 19003 W. Interstate 10, was previously acquired by Sunoco following their $6.5 billion merger with NuStar.

Why it matters

The acquisition allows the credit union to significantly grow its local operations and corporate footprint. This move follows a complex series of ownership changes involving institutional lenders and national energy firms over the past several years.

The 24-acre property is currently valued by the Bexar Central Appraisal District at $44 million. This follows a 2023 transaction where the site sold for $103 million, prior to Sunoco's acquisition of NuStar.

The players

Security Service Federal Credit Union

A San Antonio-based financial cooperative that has served the area for 70 years.

Sunoco reacquired the asset in June 2024 after purchasing NuStar. The credit union will integrate this large-scale campus into its existing local footprint near the Rim area.

NuStar sold the property to Truist Financial Corp. in 2023.

The Home Front

This transition reflects broader shifts in San Antonio corporate real estate as local institutions absorb large-scale commercial assets formerly held by energy firms. The movement underscores a period of consolidation following the recent multi-billion dollar acquisition activity in the energy sector.

Property values in the area around the I-10 corridor may be influenced by long-term occupancy changes at large commercial campuses. Residents should monitor local tax assessments as commercial properties are repurposed by new owners.

The takeaway

Large commercial transactions in the city signal long-term shifts in local corporate land use. Homeowners nearby should keep current on local zoning and property tax notices to understand how future site usage might impact the surrounding area.
