The long-empty former Spectra Energy headquarters in Houston’s Galleria is sliding deeper into financial limbo, as a $52.5 million commercial mortgage-backed loan on the property has been handed to a special servicer. The 5400 Westheimer Court tower has been largely vacant since its anchor tenant left in 2022, and the move tightens the squeeze on an owner already stuck with a hard-to-fill, single-tenant building just as the loan inches toward its 2027 maturity.
The loan was transferred to special servicing in January, after Morningstar flagged what it called an “imminent monetary default” and identified Argentic Services Company as the special servicer, according to The Real Deal. The debt was securitized in a J.P. Morgan CMBS issuance, putting it on a clock that leaves lenders with limited room to maneuver before the note comes due.
Spectra Energy, acquired by Canada-based Enbridge in 2017, vacated the Westheimer tower in 2022 when Enbridge shifted its Houston operations to Energy Center V at 915 North Eldridge Parkway, as reported by the Houston Chronicle. Industry commentary and CMBS notes indicate Enbridge kept paying rent even after moving out, but those payments stop when the full-building lease expires at the end of April, CoStar reports.
Securitization paperwork and the original loan prospectus list the borrower as a special-purpose vehicle tied to PTAD Realty and show an anticipated repayment date in October 2024, with a final maturity in October 2027. The same documents put the collateral at roughly 614,000 square feet and name PTAD Realty as the sponsor, details that help explain why the loan’s timeline and payment history are now front and center in the special servicing decision, according to filings with the SEC.
Building Value And Market Headwinds
Even basic stats on the tower come with wrinkles. Loan documents peg the building at about 614,000 square feet, while commercial data platforms round it up to roughly 632,511 square feet. The property’s valuation has also slid since the loan was originated. The Real Deal reports the building was valued at $84.5 million when the loan was issued in 2014 and was most recently appraised for tax purposes at $71.7 million in 2025. Loan commentary shows the borrower has paid down about $4.2 million, leaving roughly $48.3 million in principal still outstanding, per CoStar and public loan records.
What Special Servicing Could Mean
Handing the loan to a special servicer effectively shifts control over how the trouble gets handled. Under the pooling and servicing agreement, the special servicer can evaluate default remedies, solicit and review offers, and, if it comes to that, steer a foreclosure or sale process. Those powers are laid out in detail in the offering documents and trustee agreements on file with the SEC, and they give the servicer leeway to pursue whatever outcome it concludes best protects the CMBS certificateholders.
The broader Houston office backdrop is not exactly a seller’s market. Citywide vacancy sat at about 26.3 percent at the end of 2025, and net absorption has been clawing its way back only slowly from pandemic-era lows, making it a tall order to re-lease a full-building block in the Galleria. That environment helps explain why lenders have been trimming exposure to large, single-tenant assets and why owner-operators and opportunistic buyers are circling properties that might be priced for conversion or a discounted sale, according to Partners Real Estate.
