Often requested yet rarely found is this jewel - a single story pool home with guest quarters in Happy Valley Newhall. Tucked away on a quiet cul-de-sac, this home checks so many boxes; wide lot with RV parking; full-width front porch; private entertainer’s pool backyard with expansive patio cover, TV, playhouse and fruit trees; plus a detached studio/1-bath guest quarters. With curb appeal straight off a magazine cover, you are invited through the red front door into the fabulous updated interior. The impressively remodeled kitchen features a grand 8’ long island with seating, quartz counters, Sub-Zero fridge/freezer, Bosch convection oven/microwave/warming drawer and dishwasher, a trash compactor, plus a wet bar with wine fridge - all surrounded by a gorgeous backsplash. You’ll appreciate the vaulted ceilings, skylights, hardwood floors, stunning fireplace, large bedrooms, and a master with views of the pool and oak tree-dotted hillside. The main house bathrooms have luxuries like rain showerheads, “floating” vanities, and abalone shell tile in the master. Happy Valley is known for its charm, large private lots, and heritage oak trees, all within walking distance to hiking/biking trails, parks, shops, dining, and highly rated elementary, middle and high schools. 23515 Arlen has all that with no HOA or Mello Roos. Because it’s just minutes to the 5 and 14 freeways, you can spend more time in your oasis and less time commuting. This home truly puts the “Happy” in Happy Valley.

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.
