Opening home details…
Nearly one acre of prime residential land on Sierra Drive, located in the highly sought-after foothills of San Antonio Heights. This established community is renowned for its custom estates, mature tree-lined streets, scenic mountain views, and a sense of character and permanence rarely found in newer developments. This 39,000 SF property offers approximately 195 feet of frontage and extends roughly 260 feet in depth. The mostly level to gently rolling topography provides a versatile canvas for redevelopment or the creation of a custom estate. Zoned RS-14M under San Bernardino County. Included in the sale are 1.5 shares of the San Antonio Water Company, providing valuable irrigation capacity for landscaping or potential grove use. The site is currently improved with a 1916-era residence featuring 4 bedrooms and 2 bathrooms, along with a detached guest unit/ADU at the rear. The improvements require substantial repair, offering the opportunity to restore the existing structures or clear the site for new construction. No HOA. Located within the Upland Unified School District. Conveniently situated just minutes from the 210 Freeway, the Village of Claremont, and the extensive trail systems of the San Gabriel foothills.

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.
