Opening home details…
On one of Altadena's most treasured streets, 2509 Boulder Road sits in the Country Club neighborhood, just moments from the club, golf course, and the shops and restaurants of Mariposa Village. The flat 11,725 square foot lot is shaded by old-growth trees and mature plantings. An approximately 550 square foot casita, a two-car garage (both fully preserved), and a pool with spa remain at the rear of the property. This setting provided a poolside entertaining space between the home & casita giving it a private, resort like feel. Vegetation that has settled in over decades frames the area. The neighborhood still boasts many character homes, and the streets retain the calm beautiful vistas that define Altadena. Boulder Road is a quiet neighborly community and is not considered a drive through street. It retains its calm, tree lined, views of the mountains as well. This was once the site of an approximately 4,000 square foot two-story home, with five bedrooms and four bathrooms. With Phase 2 debris removal complete, the property is cleared and ready for what comes next. The land is being sold as-is.

No weekly rateNo published rate within 7 days of this date.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.
MLS records may be incomplete. Earlier asking prices are not sale prices.
