The owner of 90 Canal St., a 77,979-square-foot office building in Boston’s North Station submarket, has obtained $14.2 million in cash-out refinancing.

Boston Realty Advisors’ Nicholas Herz represented the borrower, 90 Canal St. LLC.

“By running a highly controlled competitive process for our client, we achieved superior loan terms not otherwise offered in the market,” Herz said in a statement.

The 6-story building is 99 percent leased with a diverse rent roll and strong occupancy history in one of Boston’s fastest-growing office submarkets.

Asking rents in the North Station submarket averaged $44.90 per square foot in the first quarter, according to JLL Research, up 36 percent over the last 12 months.
