Enchanting Balboa Island "Storybook" Cottage on the sunny side of the street in the 100 block of Onyx Avenue. There are only a handful of cottages like this on Balboa Island and none that compare to 122 Onyx. The beautifully restored main cottage has 3 bedrooms, two baths, a great room living/dining room, modern kitchen, and a private family room. Among the many unique architectural features are the living room with "Yale" style fireplace and the incredible ceiling beams that came from the first Balboa Island bridge, oak floors, arched doorways, and a "Juliet" balcony overlooking the living room. There is also a one bedroom rear apartment with private staircase, a two-car garage, and front and side patios. The owners have used the front home as a very successful vacation rental and the rear apartment has been a yearly rental. Don't miss this rare opportunity!

ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
