If you are researching Rochester from another state, your browser tabs are probably fighting with each other. One page says the median sale price is under $200,000. Another says a quarter of a million. One says homes sit for 51 days. Another says eight. None of them is obviously wrong on its face, and that is the problem.

Part of the confusion is a name collision. There is a Monroe County in New York, a Monroe County in Pennsylvania, and a Town of Monroe in Orange County, New York. Search engines do not always know which one you meant. The rest of the confusion is that different sites measure different things and label them the same way.

Here is what this post covers: where the wrong-county numbers come from, which Rochester-area figures I was able to verify and for which reporting period, where sources contradict each other, what I could not confirm at all, and a short routine you can run on any housing statistic before you let it shape an offer.

Monroe County NY vs Monroe County PA: the swap you will not notice

Search a phrase like "Monroe County housing inventory" and results for Monroe County, Pennsylvania come back mixed in with the New York ones. That county sits in the Poconos. In the results I checked, it was reported at a $318,500 median with 2.8 months of supply, and those figures came through without a clearly stated reporting period.

That is what makes the mix-up dangerous. The Poconos number is plausible. It is not absurdly high or low for an American housing market, so it does not trip any alarms. An out-of-state buyer reads $318,500, assumes it describes the Rochester area, and starts budgeting against a market that is not the one they are moving to. Editors miss it too.

The Town of Monroe in Orange County, New York adds a third possibility. It is downstate, near the Hudson Valley, hundreds of miles from Henrietta or Pittsford. Same state, same county-sounding name, entirely different market.

Three things to check on any page before you read the number:

• Does the page name a state, not just "Monroe County"? If it only says Monroe County, treat it as unidentified.
• Does it name towns you recognize? Rochester, Henrietta, Brighton, Pittsford, Irondequoit, Greece. If it names Stroudsburg or Tobyhanna, you are in Pennsylvania.
• Does the URL or breadcrumb carry a state abbreviation? Aggregator URLs usually do, and they are harder to fake than page copy.

Monroe County months of supply is the anchor number, and it is small

Months of supply tells you how long the current pool of listings would last at the current sales pace. It is the single most useful number for a relocating buyer, because it predicts how much room you have to negotiate.

For Monroe County, New York, I was able to verify 0.33 months of supply for July 2026. That is roughly ten days of inventory. It is not a typo, and it is not the same universe as the 2.8 months reported for the Pennsylvania county. If you see a supply figure for "Monroe County" anywhere north of about one month and it claims to describe Rochester, check the state before you do anything else.

A related claim I could not verify: a specific count of 169 active listings. That number appeared in material I was asked to check, but it never showed up in the sources I retrieved. I am not going to print it as fact.

Same market, same month, three different medians

This is the finding that should change how you read relocation research. For July 2026, in the same market, three aggregators published three different median sale prices.

The spread between the low and high median is more than $56,000. Sales volume is just as messy. One source reported volume up 78.6%. Another printed "643 homes sold, up from 707," which is a decline described as an increase.

When you see a headline claiming Rochester is heating up or cooling off, and it rests on figures like these, you are usually looking at a data-quality problem rather than a market turn.

When a site contradicts its own definition

Houzeo's July 2026 page for this market reports a 120.57% sale-to-list ratio and a 51-day median time on market. The same page publishes a rule of thumb that 45 to 70 days indicates a balanced market.

Both cannot describe the same month. Homes closing at more than 120% of asking price are not sitting in a balanced market. Either the days figure is measuring something other than what buyers assume, such as a list date that predates a relist, or one of the two numbers is stale. I do not know which. What I do know is that a single page gave two answers that point in opposite directions, and it takes about thirty seconds of reading to catch it.

For a fairer read of what is actually happening, a local brokerage, Elysian Homes, published a post on July 13, 2026 describing more traditional conditions returning, then followed it on August 5, 2026 with a post describing a widening split: some homes selling quickly, others sitting. That split matches what I see inside houses here. Condition, layout, and pricing decide the outcome, and averages hide both ends. An inventory change of about 28% appeared inside the July post, but I could not confirm that figure in anything I retrieved, so treat it as unverified.

Check the calendar before you check the number

Closed-sale data lags. As I write, there is no complete set of August 2026 closed sales for Rochester, Monroe County, or Henrietta, because the month has not finished settling. The newest complete sold month I found anywhere is July 2026. For Henrietta specifically, sold data stops at June 2026. Only listing-side data, meaning what is currently on the market, carries an August 2026 date.

So if a report headlines "August 2026 sales" for this area, ask what it is actually counting. Mixing July sold prices with August active listings and calling the result one month is a common shortcut, and it makes a market look like it moved when it did not.

School district fields get copied, not checked

Movoto lists Henrietta's school district as "Monroe County R-1." That is a district in Missouri. It is a database join gone wrong, almost certainly triggered by the county name.

Henrietta and West Henrietta are served by the Rush-Henrietta Central School District. I am not going to characterize any district as good or bad, and you should be suspicious of any agent who does. What I will tell you is to confirm the district and the specific attendance boundary for any address you are serious about, directly with the district office or through New York State Education Department records. Aggregator school fields are among the least reliable data on the page, and boundaries do not follow town lines.

What I could not verify, stated plainly

Transparency means listing the gaps, not just the findings. In the research behind this post:

• No data from the Greater Rochester Association of REALTORS was retrieved, which is the primary local source and the one I would normally lead with.
• Mortgage rate figures of 6.67% and 6.58% could not be confirmed. Check current rates against Freddie Mac's weekly survey directly.
• A claimed 43.87% drop in new listings could not be confirmed.
• Nothing was retrieved for Pittsford, Brighton, Mendon, Rush, Honeoye Falls, or the nearby Finger Lakes towns.
• At the town level, Henrietta figures exist for median sale price, days on market, and active listings, but months of inventory, new listings, and sale-to-list ratio do not exist in any source I found. County numbers are not a substitute, and I did not swap them in.

A five-step housing data verification routine

1. Confirm the state and the named towns before reading any figure.
2. Find the reporting period. If it is missing, the number is unusable.
3. Ask whether it is closed-sale data or listing data. They describe different moments.
4. Get the same metric from a second and third source. If they disagree by more than a rounding error, stop treating any of them as fact.
5. Check the primary source: the local association of REALTORS for sales, Freddie Mac for rates, the district or the state for schools.

Run that on any report and most of them will fall apart. The ones that survive are worth planning around.

If you are relocating and want the numbers for a specific town, street, or price band, with the source and reporting period attached and the gaps labeled as gaps, I am glad to walk through it with you. I will tell you what I do not know. Book a time with me, Khem Kadariya, and bring the report that confused you.

About this data

The figures in this post were compiled from publicly available sources including Houzeo, Movoto, Zillow, FRED (Federal Reserve Bank of St. Louis) and RochesterFirst, along with other public market data. Real estate numbers change quickly, and these were accurate as of August 2026. For current figures on a specific home, street, or town, ask me directly rather than relying on a published average.
