## Description

### Agent Description
327 Onyx Avenue is a great quiet location on Balboa Island—just two homes from the North Bay, with water views from both levels.

The lot itself is what makes this property stand out. At 40 feet wide, it’s significantly larger than most on the Island, which gives you more space, more light & parking. 

The house takes advantage of its position, with views toward the bay and a constant reminder of how close you are to the water. It’s an easy walk to the shoreline, the loop, and everything that makes Newport Beach what it is—but far enough removed to feel quiet and livable.

Properties like this don’t come up often—especially with this width, this location, and these views.
