Pull up three real estate data sites and search "Montrose home prices" and you get three different neighborhoods. Redfin's own Montrose page put the median sale price at roughly $445,000 in the first quarter of 2026. Zillow's Neartown-Montrose page put the typical home value near $609,330, with a median sale price closer to $628,534. HAR's market-area update, pulling from the same MLS everyone else licenses data from, reported a median sold price of $927,289 in the same stretch of 2026. That is not a rounding error. That is nearly half a million dollars of daylight between three sources describing the same 7.5-square-mile pocket of Houston.

The instinct is to assume one of these is wrong, or that the market is simply volatile. Neither is true. The real explanation is more useful to a buyer or seller than volatility would be: Montrose sells so few homes in a given month that the boundary a platform draws, and the handful of closings that happen to land inside it, can move the "median" more than a year of normal turnover. That mechanism is about to get a real test, because a specific 35-unit condo tower on West Gray Street is finishing construction this year and will drop directly into that thin sample.

Three Sites, Three Boundaries, Three Very Different Neighborhoods

Part of the spread comes down to geography. Redfin actually maintains two separate neighborhood pages for this part of Houston: one called "Montrose," drawn tightly, and one called "Neartown-Montrose," drawn more broadly. Over the three months ending March 2026, the tighter Montrose polygon recorded just 13 homes sold, down from 14 the year before, at a median of $445,000. Over the three months ending July 2026, the broader Neartown-Montrose polygon recorded 152 homes sold in that single month alone, at a median of $685,000. Same general address range. Same city. Twelve times the sample size and a $240,000 gap in the reported median, because the two pages are not actually measuring the same set of closings.

HAR lists Montrose under its own geomarket area, number 103, a designation that tracks closer to the historic 77006 and 77019 zip codes. Houston Properties describes that same zip-based footprint as running roughly from Allen Parkway on the north to Shepherd Drive on the west, Bagby Street on the east, and US-59 on the south. Zillow's Neartown-Montrose polygon appears to capture a wider ring than that. None of these boundaries are wrong. They are drawn by different companies for different purposes, and Montrose happens to be small enough, and its monthly sales count thin enough, that the choice of boundary changes the answer.

The Same Platform, the Same Boundary, Still Off by $150,000

Boundary mismatch explains part of the spread. It does not explain the whole thing, because HAR's own price-trend data for its own single geomarket area swings almost as wildly on its own, month to month, with no boundary change involved at all. HAR's tracked figures show a median of $735,000 in September 2025, $890,000 in December 2025, and $787,500 in March 2026. That is a swing of $155,000 within one platform's own consistent boundary, purely because a different mix of homes happened to close in each of those months.

This is what happens when a neighborhood's monthly closing count is small enough that a single expensive sale, or the absence of one, can shift the middle value of the whole group. A market that closes 150 homes a month can absorb an outlier without much drama. A market that closes 13 to 20 homes a month cannot. Every closing carries more statistical weight, and the "median" stops behaving like a stable summary of the market and starts behaving like a coin flip on which dozen houses happened to sell that month.

A Single Address About to Make This Worse

Montrose is entering a stretch where that coin flip gets heavier stakes. On West Gray Street, at the block spanning roughly 419 to 515 W. Gray, developers Tannos Development Group and Wolfgramm Capital are finishing The Madison, a seven-story, 35-unit condo building replacing a row of aging 1930s-era fourplex apartments. Units run 2,000 to 3,200 square feet, with pricing reported in the $1.5 million to $2.4 million range as the building neared its sales launch. Construction began in earnest after demolition in 2024, and the project has been expected to reach completion and start closings sometime in 2026, which puts the building's first wave of sales squarely in the same calendar window as the price data everyone is currently arguing over.

Run the arithmetic. If Redfin's Montrose page is closing roughly 13 to 14 homes in a typical month, and even four or five Madison units close in the same reporting period at $1.5 million-plus, those sales alone could be enough to drag that month's median up by hundreds of thousands of dollars, not because bungalows and townhomes down the street got more expensive, but because the mix of what sold changed. The reverse is just as true. A quiet month with no Madison closings and a cluster of smaller condo resales could make the same neighborhood look like it's cooling off. Neither read would describe what actually happened to the value of a typical Montrose home. Both would just describe which dozen properties closed escrow that month.

The Madison is not an isolated data point either. A few blocks south, Skanska has been advancing plans for Starling, a mixed-use retail and multifamily project at the corner of Westheimer and Montrose Boulevard, on the site that once housed a Kroger and a Half Price Books. And Montrose Boulevard itself is mid-reconstruction: TIRZ 27's Montrose Boulevard Improvement Project is rebuilding the corridor from Allen Parkway to West Clay Street as a four-lane road with a new median, wider sidewalks, added trees, and a pedestrian bridge, a roughly year-long undertaking. None of that changes what a bungalow is worth. It does mean Montrose is absorbing more large, lumpy capital events at once than its usual sales volume is built to smooth out cleanly.

What to Actually Compare

None of this means Montrose data is useless. It means a single blended median is the wrong tool for the question a buyer or seller is actually asking. A few adjustments make the numbers far more honest.

1. Filter by product type before you filter by neighborhood. Intown Homes' aggregated data put Montrose townhomes in a February 2026 range of $405,000 to $1,325,000, with a median of $719,500. That single-product number tells you far more about what a townhome buyer will actually pay than a blended median that mixes townhomes, historic bungalows, and high-rise condos into one figure.

2. Ask for a trailing six-to-twelve-month window, not a single month. A monthly median in a market this thin is closer to a snapshot of who happened to close than a trend line. Stretching the window smooths out the effect of any one large building coming online.

3. Watch price per square foot within the same product type. Redfin's per-square-foot figures showed the same boundary problem as the median: $232 per square foot on the tight Montrose page versus $315 per square foot on the Neartown-Montrose page. The number is only useful if you know which polygon and which housing type it's describing.

4. Treat new-construction closings as their own category. When a project the size of The Madison starts closing, its sales belong in a conversation about luxury condo pricing, not in the same bucket as a 1920s bungalow resale three blocks away.

If you're weighing Montrose against a neighborhood like the Heights, keep the same caution in mind, just pointed the other direction. Heights data has been reported as a thicker, steadier sample, a $690,000 median and a nine-day average market time as of 2025, because more homes close there each month and the boundary most sites use is more consistent. That does not make Montrose less valuable. It means Montrose asks a sharper question than "what's the median" before the number is useful.

If you're trying to figure out what a specific Montrose address is actually worth, or what your budget actually buys once you filter out the noise, that's the conversation worth having before you make an offer or set a list price. New Heights Group works this neighborhood block by block, and can walk you through the comps that actually apply to your situation instead of the headline number a portal generated last month.
