Old Southwest and Caughlin Ranch Share a ZIP Code. Their Housing Markets Don't.

Type "median home price 89519" into a search bar and you'll get a single, confident number. Walk the streets behind that ZIP code and you'll find two neighborhoods that price homes on almost opposite logic. Old Southwest and Caughlin Ranch, two of the most asked-about addresses in Southwest Reno, both sit inside 89519. The blended figure that ZIP code produces lands somewhere between the two markets and describes neither one well, and that mismatch changes how a relocating buyer should read every listing in both places.

As of June 2026, active-listing data for ZIP 89519 put the median list price near $725,000 at roughly $330 per square foot. That number is accurate as a ZIP-level average. It is close to useless for pricing a specific house, because it averages a neighborhood of century-old bungalows against a neighborhood of 1980s-and-later custom estates, two housing stocks that were never meant to be compared on the same curve.

What's actually on each side of that ZIP line

Old Southwest is the older of the two by decades. Most of its homes went up between the 1920s and the 1950s in Craftsman, Tudor, and Spanish Revival styles, with a meaningful pocket of mid-century modern construction added through the 1960s. Lots run small and tight near the urban core, typically 0.15 to 0.25 acre, widening to a half acre or more at the neighborhood's suburban edges. The neighborhood average sits near 0.30 acre. Most of Old Southwest carries no formal homeowners association, though a handful of older parcels still have recorded covenants focused on preserving architectural character. What you're buying is proximity: walkable streets close to the Truckee River, Midtown, and downtown, on land that was subdivided before most of Reno existed.

Caughlin Ranch is a different animal entirely. The community traces back to a ranch house built in 1874 in Virginia City, disassembled and moved to its current site on Mayberry Drive in 1895 after a marriage connected the two properties. What's there today is a master-planned neighborhood of more than 2,500 homes, developed from the 1980s onward, stretching from the Truckee River toward Skyline Boulevard. Homeowners pay HOA dues of roughly $60 to $160 a month, which cover trail upkeep, greenbelt irrigation, and pond maintenance. Residents get a private trail network, Village Green Park with its summer concert series, and easy access to Idlewild Park just to the north, where Food Truck Friday draws crowds through the warm months and the Tahoe-Pyramid Bikeway threads along the river. Lot sizes here span an unusually wide range within a single community, from cozy parcels near a tenth of an acre to custom lots over an acre and a half in gated pockets like Promontory Pointe and Eagles Nest, where prices push past $2 million to $3 million.

The number that flips the story

Here's where the two markets stop rhyming. Caughlin Ranch carries the higher sticker price. Its median sale price ran near $1.0 million to $1.04 million over the three months ending May 2026, and a June 2026 snapshot put the median list closer to $1.13 million. Old Southwest's median list price across several current listing snapshots taken between April and July 2026 clustered between roughly $627,000 and $740,000, well under half of Caughlin Ranch's ceiling in some months.

Now look at price per square foot instead of total price, and the ranking reverses. A June 2026 snapshot put Caughlin Ranch's price per square foot near $388. Old Southwest's ran higher across the same year, commonly $450 to $565 per square foot depending on the month sampled, well above the $330 figure the blended ZIP 89519 average reports. In other words, the blended ZIP number actually sits closer to Caughlin Ranch's real per-square-foot cost than to Old Southwest's, which quietly understates what Old Southwest land costs by more than a hundred dollars a square foot.

That's the part a headline median hides. The neighborhood with the lower total price is charging more per square foot, and the neighborhood with the much higher total price is charging less per square foot. A buyer scanning only the median would assume Old Southwest is the value play. Per square foot, it's the more expensive place to buy.

It's worth flagging that these neighborhood-level figures don't always agree month to month. One tracker showed Caughlin Ranch's median up nearly 10 percent year over year through May 2026, while a different snapshot for June showed a sharp decline over the same twelve months. Neighborhood-level sales counts are small enough that a handful of unusually large or unusually modest closings can swing the median hard in either direction without signaling any real change in the market. Treat any single month's neighborhood figure as a data point, not a verdict.

Why the same square foot costs different amounts

The mechanism isn't complicated once you separate what each dollar is actually purchasing. In Old Southwest, you're largely paying for land and location. The average home is smaller, commonly 2,200 to 2,800 square feet, with some historic cottages as compact as 800 to 1,200 square feet, sitting on parcels that were platted before Reno's population tripled. That land can't be recreated. There's no new supply of century-old, river-adjacent lots inside city limits, so the price holds up on scarcity even when the structure itself is modest.

In Caughlin Ranch, a larger share of the price reflects the structure and the master-planned infrastructure around it: bigger floor plans, three-car garages, HOA-maintained trails and greenbelts, and in the higher sub-associations, custom construction on generous lots. Because homes here tend to run larger, the same dollar spreads across more square footage, pulling the per-square-foot number down even as the total price climbs.

Neither approach is the better deal in the abstract. They're two different products. A buyer who wants space, newer systems, and a maintained trail network gets more structure per dollar in Caughlin Ranch. A buyer who wants irreplaceable in-town land, mature trees, and pre-war architectural character pays a real premium for that scarcity in Old Southwest, even though the total check is smaller.

Questions worth asking before you write an offer

Because these two markets sit inside one ZIP code but behave so differently, generic comps won't get you to an accurate number. Before making an offer in either neighborhood, it helps to ask:

• Which sub-association is this Caughlin Ranch home in, and was it built in the community's original 1980s and 1990s core or as newer custom infill? Systems, finishes, and lot size can vary sharply between the two.
• Does this specific Old Southwest parcel carry any older recorded covenants, even though the neighborhood has no master HOA?
• What's the actual lot size, and how does it compare with the neighborhood average rather than the citywide one?
• If there's an HOA, are the accounts current and is there a pending special assessment attached to the property?
• Was the home priced against homes on its own street, or against a citywide or ZIP-level average that blends two unrelated markets?

The backdrop both neighborhoods sit inside

Both markets are trading inside a tight citywide environment. Reno's overall median single-family sale price reached $715,000 in July 2026, up 13.1 percent from July 2025, with active inventory down nearly 25 percent from the year before and roughly two months of supply citywide, a level that still favors sellers. That tightness applies most to the sub-$1 million core that includes most of Old Southwest and Caughlin Ranch's entry-level resales. The picture changes at the top: homes priced above $1.5 million, a tier that touches Caughlin Ranch's custom estates and gated enclaves, carried closer to nine months of supply as of mid-July 2026, a buyer's market by any normal measure. A relocating buyer with the flexibility to shop that upper tier in Caughlin Ranch has real negotiating room that doesn't exist for a $650,000 Old Southwest bungalow with three other offers on the table.

The lesson isn't that one neighborhood beats the other. It's that a ZIP-level median was never built to answer the question a relocating buyer is actually asking. Old Southwest and Caughlin Ranch happen to share a mailing code. They don't share a market, and pricing either one off the other's number is how buyers overpay for scarcity they didn't know they were buying, or underpay attention to square footage they thought they were getting for free.
