Search for "Weibel home prices" this month and you'll find four confident numbers. One site puts the average at $2.29 million, down 18 percent from a year ago. Another reports a median of $2,524,000, down less than 4 percent. A third cites $2,680,000, also down modestly. A fourth, pulling from the same zip code, shows an average up 25 percent year over year. Same neighborhood, same rough window of time, four different stories about which direction the market is moving.
None of these sites made an error. They're measuring two different housing markets that happen to share one name.

If you're comparing Weibel to Pleasanton or Mission San Jose using any single one of these numbers, you're comparing against a figure that could have landed anywhere in a $600,000 range depending on which handful of closings happened to fall inside the measurement window. That's not a market signal. That's the arithmetic of a small, split sample.
One Name, Two Housing Stocks
Weibel's housing stock was built almost entirely between the mid-1960s and the early 1990s, a mix of ranch-style, split-level and contemporary homes on lots that run from roughly a tenth of an acre up to a full acre. Walk through the open, non-gated streets and you'll find three- to five-bedroom homes in the 1,200 to 3,400 square foot range, the kind of tract housing that defined Fremont's postwar growth years. Priced on their own, these homes have consistently traded somewhere in the $1.6 million to $2.2 million band.
Then there's the other Weibel. Tucked against the eastern edge, where the streets stop being a grid and start curving up toward the foothills, sit the gated communities of Avalon Heights and Hidden Valley Terrace. These are custom estates, not tract homes: 24-hour gated and guarded, lots that stretch past half an acre, floor plans running 3,000 to nearly 5,000 square feet, with amenities like pools, multiple fireplaces and unobstructed views of Mission Peak and the bay. One active Avalon Heights listing this year asked just under $5 million for a 4,904 square foot, five-bedroom estate. These homes don't compete in the same price tier as the tract homes three streets over. They compete with each other.
Part of the disagreement between data sources starts with the map itself. Some platforms draw Weibel's boundary to include the gated Avalon Heights and Hidden Valley Terrace section. Others carve that section into a separate polygon labeled Vineyards-Avalon, a neighboring area bounded roughly by Interstate 880 and Mission Boulevard. Depending on which cartographer drew the line that month, a $4 million estate sale either pulls the reported Weibel median sharply upward or doesn't count toward it at all. Weibel proper sits south of Cameron Hills, north of Vineyards-Avalon, framed by I-680 to the west, Mission Boulevard to the east and Durham Road to the north, and different data providers slice that boundary differently when a listing sits near the edge.
What Actually Closed This Spring
The clearest way to see the split isn't in an aggregated average. It's in two individual closings, two months apart, on opposite sides of the gate.
On February 18, 2026, a four-bedroom, 2.5-bath home on Argus Court, built in 1988 and running 2,388 square feet, closed 13 percent above its asking price at $1,179 a square foot after eight days on market. That's a healthy, competitive sale by any measure, and it's exactly the kind of result you'd expect from Weibel's open tract stock: motivated buyers, a tight bidding window, a price that tracks with the neighborhood's older ranch-home character.
Two months later, on April 22, 2026, a four-bedroom, 3.5-bath home on Degas Terrace, built in 1998 and running 3,083 square feet, closed at $4,438,000, 11 percent above asking, at $1,440 a square foot, after six days on market. Joseph Sabeh of Golden Gate Sotheby's International Realty represented that sale. Both transactions moved quickly. Both closed well over ask. But one sold for roughly $2.8 million less per home than the other, and if either one alone had been the closing that landed inside a given month's reporting window, it would have swung the "Weibel median" by hundreds of thousands of dollars in either direction.
This is the piece the headline percentages miss. The market underneath both segments is strong. Sellers on both sides of the gate are getting multiple offers and closing in days, not months. What varies isn't demand. It's which product happened to trade that month, and how much weight a thin sample gives to a single outlier sale.
Reading a Weibel Listing Correctly
If you're comparing neighborhoods and Weibel's number keeps jumping around depending on the source, the fix isn't to find a fifth site and hope it's more accurate. It's to ask a more specific question about any individual listing before you trust the price against it.
Street names are a reasonable first clue. Addresses on Avalon Heights Terrace or within Hidden Valley Terrace are almost always inside the gated estate tier. A listing on a court or a straightforward numbered street, closer to the I-680 side of the boundary, is more likely part of the original tract build. Built year matters too. Homes dated to the 1960s through the 1980s tend to be the ranch and split-level originals. Homes built from the mid-1990s into the 2000s are more often part of the custom-estate wave. And any mention of a homeowners association, a guard gate, or "gated community" in the listing description is the clearest signal of all, since HOA dues and architectural review are part of what separates the two products beyond square footage alone.
None of this is a judgment about which Weibel is the better buy. Families looking for a solid four-bedroom home near Fred E. Weibel Elementary and Arroyo Agua Caliente Park will find real value in the open tract streets. Buyers looking for a private, view-oriented estate within the same school boundaries will find that further east, behind the gate. The mistake is treating a single blended number as if it describes either experience accurately.
Quick Answers
Why do reported Weibel home prices vary by hundreds of thousands of dollars between sites? Because "Weibel" covers two structurally different housing products, an open 1960s-90s tract and a gated custom-estate enclave, and different platforms draw the neighborhood boundary to include or exclude the gated section. With relatively few monthly closings, whichever product happens to sell in a given window skews the average.
How can I tell if a specific Weibel listing is inside a gated community? Check the street name against Avalon Heights Terrace or Hidden Valley Terrace, look for HOA fees or a mention of a guard gate in the listing description, and note the built year. Homes from the mid-1990s forward in this neighborhood are more likely part of the estate tier.
Is Weibel currently a buyer's market or a seller's market? Recent closings on both sides of the boundary sold above asking price within one to two weeks, which points to a competitive market for well-priced homes in both the tract and estate segments. That said, conditions can shift by month and by product type, so the most reliable read comes from comparing a specific home against recent closings of the same type, not against a blended neighborhood average.
If you're weighing a move into Weibel, or trying to figure out which side of the gate makes sense for your family or your next listing, that's exactly the kind of local read a blended statistic can't give you. Joseph Sabeh Group has worked transactions on both sides of this neighborhood's divide and can walk you through what a specific address is actually worth before you make an offer or set a price.
