We have to hand it to actress Kathy Najimy. The “Sister Act” movie star who also appeared in the HBO’s “Veep” bought a really big Midtown apartment for $2.6 million.

The unit is in the Carnegie House co-op at 100 West 57th Street, and sprawls 2,500 square feet, not including a 600-square-foot terrace. That puts the per-square-foot price at $1,100 — a bargain for that location, or anywhere in NYC these days.

Plus, the co-op allows pied-a-terre use, as well as parents buying for kids and pets. In other words: Anything appears to go, which is not that easy to find in NYC co-ops. It looks like the co-op went into contract in February after a December 2014 listing, but finally closed this month.

So what’s the potential catch? The Real Deal reports that the ground under the 324-unit Carnegie House has been sold to investor David Werner and  Rubin Schron and the Cohen family for $285 million last year. The closing took place this spring. The investment deal was based on an upcoming ground rent reset, which will be triggered in about 10 years. Never a dull moment in NYC real estate, especially on a corner like Carnegie House, which spans 56th to 57th Street along 6th Avenue.
