Welcome to 712 Gemstone Drive, a beautifully upgraded home tucked inside one of San Marcos' best-kept secrets — Rancho Tesoro. Gated, quiet, and surrounded by rolling hills and trails, this hidden gem is ideal for families craving space, nature, and community. Thoughtfully designed with modern upgrades and timeless finishes, the home features a light-filled open-concept layout with luxury vinyl plank flooring, a white-on-white chef’s kitchen with quartz counters and oversized island, and seamless indoor-outdoor flow to a private backyard oasis. Host friends around the fire pit, practice your short game on the putting green, or watch the kids play on the turf, this yard is built for connection and joy. The first floor includes a full bedroom and bath, ideal for guests, multigenerational living, or a private home office. Upstairs, the spacious primary suite feels like a retreat with spa-inspired bath and dual vanities. You’ll love the loft/flex space and well-sized secondary bedrooms — perfect for growing families or hybrid work setups. Rancho Tesoro is a beloved yet often undiscovered master-planned community in 92078. Residents enjoy resort-style amenities including a private pool, playground, BBQ areas, and gated trails connecting to Discovery Lake, South Lake, and Double Peak. This location is perfect for outdoor lovers: morning walks around Discovery Lake, sunset hikes to Double Peak, or biking to Lake San Marcos for dinner at Amalfi. Minutes to Urban Sweet Cafe, Mr. Taco, SETS, Tabu Sushi, Players Sports Bar, Vine & Tap, and the North City Friday Farmers Market — this home offers the full North County lifestyle. If you’ve been searching for a place where the kids can ride bikes safely, where you can hike before work, and where neighbors actually know your name… this is it. Come experience what life could look like in one of San Marcos’ most special communities.

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.
