Two homes hit the Oak Park market the same week this spring. One was a two-bedroom condo in a gated complex, listed just under $500,000. The other was a four-bedroom single-family home on a cul-de-sac, listed north of $1.3 million. Both sold within a month. Both are, technically, "the median Oak Park home." Neither one is what most buyers picture when they hear the number quoted on a real estate site.
That gap is not a fluke of one busy week. It is the whole story of how Oak Park's headline price gets built, and it explains why the number you see quoted on one platform rarely matches the number quoted on another for the same town in the same month.
The Number Everyone Quotes Isn't One Number
Ask three different sources what Oak Park homes cost right now and you will get three different answers, and not by a little. Over the three months ending May 2026, Redfin's data put the median sale price at $1.2 million. Zillow's tracker, updated through the end of July 2026, put the average home value at $1,130,157. A separate market summary attributed to Realtor.com for May 2026 reported a median sold price of $1,250,000 against a median listing price of $949,000, a gap of roughly $300,000 between what sellers were asking and what buyers were paying that same month.
None of these sources are wrong. They are measuring different slices of the same lopsided pie. Oak Park's housing stock, according to demographic data from NeighborhoodScout, breaks down to roughly 63.56 percent single-family detached homes, with the remainder split between row houses and other attached homes at 15.48 percent and larger apartment or condo buildings at 13.25 percent. When a "median" gets calculated, it depends entirely on how many of each type happened to close escrow that particular month. A month heavy on single-family sales pulls the median up. A month with more condo turnover pulls it down. The number is real. It is just not stable, because the mix behind it isn't stable.
The Dollar Gap Is Bigger Than the Real Gap
Here is where it gets useful for anyone actually comparing homes. One market data aggregator's breakdown of Oak Park pricing put the average condo near $475,000 against an average single-family home near $1,295,000, a difference of over $800,000. That number alone would suggest single-family land in Oak Park is worth roughly three times what a condo unit is worth.
It isn't. Zip-code-level data for 91377 shows single-family homes running only about $33 more per square foot than condos. That is the number that actually reflects what buyers are paying for location, land, and the single-family label itself, once you strip out the fact that single-family homes in Oak Park are simply bigger structures. A condo buyer isn't getting less house per dollar because Oak Park land is scarce for them specifically. They are getting less house because condos are smaller units, full stop. Most of that eye-catching $800,000 gap is square footage, not scarcity.
This matters if you are cross-shopping Oak Park against Agoura Hills, Calabasas, or Thousand Oaks using headline medians. A $1.2 million median in one town and a $950,000 median in another does not tell you whether you are comparing similar homes. It might just mean one town's transactions that month leaned single-family and the other leaned condo. The $33-per-square-foot figure is a far more honest yardstick than the six-figure sticker difference, because it holds size constant.
Why the Mix Isn't Going to Change
If Oak Park were still growing, this problem would eventually sort itself out as new construction shifted the ratio one way or another. It isn't going to, because Oak Park can't grow the way other Ventura County communities can. Ventura County's own planning documents for the area describe Oak Park as the county's largest unincorporated community, built out by 2002, with the open space in and around it already dedicated as permanent parkland. Palo Comado Canyon runs along the town's eastern edge, and Paramount Ranch, a former movie ranch with an old-West set used in Hollywood productions, sits just to the south. Both are protected open space, not future subdivisions.
That boundary is doing real work in this price story. A town that's still permitting new tracts can dilute a lopsided housing mix over time. Oak Park cannot. The 64-36 split between single-family and attached housing that exists today is close to the split that will exist in five years and ten years, because there is no undeveloped land left to tip it. Whatever ratio of single-family to condo sales drives next month's median is likely to keep driving it for a long time to come.
The Same Split Shows Up in Rent
If you're evaluating Oak Park as a landlord or an investor rather than an owner-occupant, the identical pattern reappears in the rental numbers, and it's worth catching before you price a listing off the wrong one. Realtor.com's May 2026 data put the median rent for Oak Park at $4,250 a month. Zillow's rental data for the same period put the average rent at $3,123, up 3 percent year over year. That's a gap of over $1,100 between two numbers both labeled "Oak Park rent."
The explanation is the housing mix again. A separate look at standalone rental houses specifically, tracked through the end of July 2026, put the average rent for a freestanding single-family home in Oak Park at $7,331 a month. Once you isolate detached houses from the condos and townhomes blended into the other averages, the number jumps substantially. If you own a single-family rental and you price it off a blended market average instead of a same-type comparable, you will likely underprice it. If you own a condo and price it off the single-family figure, you'll sit unrented.
What to Actually Do With This
The fix isn't complicated once you know the mechanism. Before you treat any Oak Park median as a benchmark, ask what it's blending. If you're comparing your single-family home to "the Oak Park median," make sure that median is built from single-family sales, not a townhome-and-condo average dragging the number down. If you're pricing a condo, don't anchor to a number that's secretly half single-family homes. The per-square-foot figure is almost always a more honest comparison than the sticker price, because it survives the mix problem that the headline number doesn't.
This is the kind of detail that's easy to miss scrolling past a home value estimate and easy to get wrong when it's your own listing or your own offer on the line. If you want a read on what your specific street or your specific home type is actually doing right now, rather than a blended number that may or may not include homes like yours, Happy SoCal Homes is a call away. Schedule your free consultation and we'll walk through the comparables that actually match your home, not just the ones that happen to be in the same zip code.
A Few Quick Questions
Is Oak Park in Los Angeles County or Ventura County? Oak Park is in Ventura County. It sits just west of the Los Angeles County line near Agoura Hills and Calabasas, which is part of why it gets grouped with those cities in casual conversation even though its county services and planning come from Ventura County.
Will new construction ever change this housing mix? Unlikely in any meaningful way. Ventura County's planning documents describe the community as built out since 2002, with surrounding land already set aside as parkland including areas near Palo Comado Canyon. There is little to no room for new subdivisions that would shift the current single-family-to-condo ratio.
Which number should I trust when comparing Oak Park to a nearby city? Whichever one specifies the housing type. A single-family median compared to another town's single-family median tells you something real. A blended median compared to another town's blended median only tells you something real if both towns happen to have a similar mix that month, which is not something you can assume.
