If you have spent a few evenings searching for homes for sale in Henrietta NY, you have probably noticed that no two websites agree on how many houses exist. One page says a few dozen. Another says a few hundred. A third gives you a number with no date attached at all.

This post explains where those counts come from, why they disagree, which figures in the current data are trustworthy and which are not, and what a buyer in Henrietta, West Henrietta or Rush should actually do about it. I am going to show my arithmetic and name the gaps rather than paper over them.

Two counts for the same month, and neither one is a full count

Here are two published active-listing figures for July 2026, both labelled Rochester.

The 169 figure comes out of the Houzeo data. Multiply 509 sales by 0.33 months of supply and you get 168. Divide 169 by 509 and you get 0.332 months. So the listing count and the months-of-supply figure are not two independent confirmations of a tight market. They are one fact stated twice. That matters, because a stat repeated in two forms feels twice as solid as it is.

Now the bigger problem. Rochester has a population of roughly 210,000. Neither 56 nor 169 is a plausible count of everything on the market in a city that size. Both are almost certainly filtered subsets: single-family only, or a partial set of ZIP codes, or a snapshot taken on one day and never refreshed. When a site does not publish its filters, you cannot tell which.

The filters that quietly shrink a listing count

A listing count is the answer to a question. Change the question and the answer changes. These are the filters that move the number most, and most sites apply at least a few of them by default without telling you.

• Property type. Single-family only excludes townhomes, condos, two-family properties and manufactured homes. In the south county corridor that can remove a meaningful share of the entry-price stock.
• Status. Active only versus active plus pending, contingent and coming soon. A contingent listing can come back on the market next week.
• Geography. ZIP code versus town line versus school district. These three boundaries do not overlap in Henrietta, and searching by one of them will hide homes that sit inside the other two.
• Price band. A default cap set by the site, not by you.
• Land and new construction. Vacant lots and to-be-built homes are frequently excluded, which matters in Rush and West Henrietta where they exist.
• Refresh date. Some aggregator pages show a count generated days or weeks earlier and carry no timestamp.

Why none of these numbers describe Henrietta, West Henrietta or Rush

This is the part most articles skip. Every inventory and price figure above is labelled Rochester or Monroe County. None of it is town-level data for our area.

The word Rochester is doing a lot of work in these datasets, and it does not mean the same thing twice. For July 2026, published median prices for Rochester ranged from $199,000 (Movoto) to $230,000 (Houzeo) to $255,000 (Resideline). Realtor.com data via FRED put the Monroe County median listing price at $319,900 in May 2026. That is a spread of nearly 61 percent for what is supposedly the same market at roughly the same moment. The gap exists because some sources mean the city and others mean the county.

Plenty of homes in Henrietta and West Henrietta carry a Rochester mailing address. Whether a given property lands inside a city-labelled dataset depends on how that dataset was built. So when you ask how many homes are for sale in Rochester NY and get 56, you are not getting an answer about Rush NY homes for sale, and you are certainly not getting a count of West Henrietta real estate listings.

The most authoritative local price figure I have is from the New York State Association of Realtors, reported by the Rochester Business Journal: the Monroe County median sale price hit $308,500 in May 2026, a record high. That is board-of-Realtors data rather than a scraped estimate. It is also three months old and county-wide.

The pace figures are more useful than the count

If you want to know how hard it will be to buy, look at speed, not inventory volume. Here the sources cluster tightly, with one exception.

• Zillow: homes going pending in around 8 days for Monroe County, as of 30 April 2026.
• Movoto: 13 average days on market in July 2026, the same as a year earlier.
• Redfin: 11 days on market for a Rochester neighbourhood over the three months ending May 2026, also unchanged year over year.
• Houzeo: 51 days on market, July 2026.

Three sources say 8 to 13 days. One says 51. The 51-day figure also contradicts other numbers on the same page: 0.33 months of supply works out to about 10 days of supply. Treat 8 to 13 days as the credible range and treat 51 as an artifact.

What that means in practice is that you need financing sorted and a plan for viewing a new listing within a day or two of it appearing. A listing count of 56 or 169 does not tell you that. Turnover speed does.

Sales volume is where I would stop trusting the aggregators entirely

Houzeo reported 509 Rochester sales in July 2026, up 78.6 percent year over year, which implies only 285 sales in July 2025. Movoto reported 643 sales in July 2026, described as up from 707 last year. But 643 is 9.1 percent lower than 707, not higher. One source contains a self-contradicting sentence and the other reports a volume jump that is far too large to be organic in a market this size. I would not use either figure, and neither should you.

What is actually current, and what is not

Mortgage rates are the one number that is genuinely up to date. Freddie Mac put the 30-year fixed at 6.67 percent for the week of 13 August 2026, down from 6.69 percent the previous week and up from 6.58 percent a year earlier. That is a 9 basis point increase over twelve months. On a $300,000 loan it works out to roughly $18 a month. The 15-year fixed averaged 5.96 percent, against 5.71 percent a year ago.

Local sales data runs behind. As of mid-August 2026, the freshest aggregator sales data is July 2026, and the freshest primary-source county figure is May 2026. August closings will not be published until early to mid September. Any page claiming to show you August home prices in this area is showing you a model, not a closing.

Direction is contested too. The Rochester Business Journal ran a June 2026 piece headlined that housing inventory was on the rise in Monroe County while prices also rose. Other summaries describe inventory falling sharply. Meanwhile, national mid-year coverage notes that the cooling story is largely a Sun Belt story, and that parts of the Northeast have gone the other way, with buyers competing over shrinking inventory. That is why the headlines you read do not match what you see at an open house here.

How to build a search that actually shows you everything

• Search by town and by ZIP separately, then compare. Henrietta, West Henrietta and Rush do not line up neatly with postal boundaries.
• Turn off the property-type default. Include condos, townhomes and two-family listings if your financing allows them.
• Include pending and contingent listings so you can see what is competing and what may return.
• Note the Rush-Henrietta Central School District boundary separately from the town line. They are not the same shape.
• Set alerts on the MLS feed rather than checking aggregator pages, so you see a listing the day it goes live rather than whenever a page refreshes.
• Ask for the sold sheet for the specific street or subdivision you are considering. Comparable sales beat any city-wide median.

I have walked through a lot of these houses in Henrietta, West Henrietta and Rush, and I can tell you what a listing photo will not: which basements stay dry, which lots drain, which 1960s ranches have had the panel updated and which have not. If you want a straight count of what is available in a specific town, with the filters visible and the reporting dates attached, book a time with me and we will go through it together.

About this data

The figures in this post were compiled from publicly available sources including Houzeo, Movoto, Redfin, Zillow and FRED (Federal Reserve Bank of St. Louis), 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.
