What happened
A joint venture of Wharton Properties, Aurora Capital Associates and ACHS Management has secured a $45.5 million loan to refinance 511 Fifth Avenue, an office building in Midtown Manhattan. Commercial Observer reported the deal on October 20, 2026.
ACORE Capital provided the loan, which is nonrecourse. Meridian Capital Group arranged the debt with a team led by Aaron Birnbaum, co-founder and executive vice president at Meridian. Birnbaum said new tenants signed while the loan was in process.
The 18-story building was built in 1918 and sits at the corner of Fifth Avenue and 43rd Street, a block north of the New York Public Library's main building. It was recently redeveloped with 16,000 square feet of renovated space. Recent leases include two-floor deals with GE Aerospace and WeWork and a 9,812-square-foot lease with French consulting firm Wavestone.
The 15th floor has a lounge, a juice bar and a fitness center for tenants. North Face opened a two-story, 21,000-square-foot flagship store at the base of the building in November 2025. Spokespeople for ACORE and the three sponsors did not immediately respond to Commercial Observer's requests for comment.

What it means
Buyers and owners
This is a commercial office deal with no apartments. Its main value for property owners is as a sign that lenders are still refinancing Midtown office buildings that show recent leasing activity.
Landlords
The deal has no direct effect on residential landlords. Small owners shopping for their own refinancing should not read the terms of a large office loan as a guide to residential lending.
Tenants and voucher holders
The building has no residential units, so this refinancing does not affect apartment tenants, voucher holders or rent-regulated housing.
The highlights
- The 18-story building, built in 1918, sits at Fifth Avenue and 43rd Street.
- GE Aerospace and WeWork signed two-floor deals; Wavestone took 9,812 square feet.
- Meridian Capital Group's Aaron Birnbaum arranged the nonrecourse loan.
Why it matters Landlords
Lenders are still refinancing older Manhattan office buildings that have been renovated and show new leasing.

Background
In a refinancing, an owner takes out a new loan to pay off existing debt, often to get new terms or to pull out cash. A nonrecourse loan generally means the lender can look only to the property itself if the borrower defaults, not to the owners' other assets, though such loans usually include standard exceptions for things like fraud. In New York City, large commercial loans like this are often arranged by mortgage brokerage firms that match owners with banks, debt funds and other lenders.
