Ask two different real estate data sites what happened to home prices in Hummelstown this year and you will get two different answers. One says prices are up 27 percent. Another says 9 percent. Neither is wrong. They are measuring different things, and the gap between them tells you more about how to shop this market than either number does on its own.
As of June 2026, Redfin listed Hummelstown's average home price at $440,000, up 27.5 percent from a year earlier. The same report put the median sale price, calculated over the three months ending in May 2026, at $262,000, up 9.3 percent over the same period the year before. A gap that wide between average and median usually points to one thing: the market is small enough that a handful of expensive sales can pull the average up without moving the middle at all.
Two Sales, One Day Apart
Redfin counted just 14 closed sales in Hummelstown in May 2026. In that same small batch, a four-bedroom home on Thrush Drive closed for $1,070,000 on May 29, a 4,368-square-foot property. One day earlier, a two-bedroom on High Pointe Drive closed for $259,900. Same month, same borough, more than a four-fold difference in price. A week into June, a four-bedroom on Waltonville Road closed for $800,000, keeping the average elevated even as most of that month's other closings landed well under $400,000.
That kind of spread barely registers in a large market. Harrisburg or Philadelphia can close a million-dollar home and a $260,000 home in the same week and the average will not budge, because thousands of other transactions absorb the difference. Hummelstown closes maybe a dozen homes some months. One outsized sale can move the average by tens of thousands of dollars while the median, the price sitting at the exact middle of that stack of closings, holds nearly still. This is not a sign the market changed its mind about what a typical Hummelstown home is worth. It is a sign the sample size is small enough that the loudest number in the room does not represent the room.
One Zip Code, Two Housing Markets
The reason Hummelstown can produce a $259,900 sale and a $1,070,000 sale in the same month is not randomness. It is inventory. The borough's walkable core along Main Street and Quarry Road is built out with older Victorian, Federal, and craftsman homes, the kind of housing stock that gives Hummelstown its character and its lower entry price. A buyer looking at that part of town is within walking distance of Main Street spots like The 1762, Soda Jerk Diner & Dairy Bar, Hidden Still Spirits, and Reunion Cocktails Provisions, and the homes reflect the age of the neighborhood around them.
The borough's edges tell a different story. Newer construction and townhome product, including the Hershey High Pointe community, sit closer to Hershey Medical Center and the Hershey employment corridor. Detached single-family homes on larger lots, including neighborhoods like Deer Run near Schiavoni Park's 2.5-mile paved trail, push into a higher price tier with more square footage and more recent construction. Two products, two very different price points, one Hummelstown zip code.
This is not unique to Redfin's numbers. A separate market snapshot from March 2026 showed the same pattern: a median home price of $350,000 against an average sale price of $389,291. Different month, different source, same underlying story. The gap between average and median in Hummelstown is not a one-time statistical fluke. It is a structural feature of a small town with two distinct housing products sold under one name.
What This Means If You're Comparing Hummelstown to Somewhere Else
If you are weighing Hummelstown against another Hershey-corridor town using a single headline price, you are comparing an average that could be quietly inflated by one large sale against a median from a town with a different mix of housing stock entirely. A few things are worth doing before you draw a conclusion:
- Ask for the range, not just the headline number. A $1 million sale and a $260,000 sale in the same month tell you the town has two products, not one.
- Ask what specific streets or developments recent comps came from. A comp from Hershey High Pointe means something different than a comp from Main Street.
- Look at price per square foot alongside the sale price. Redfin listed Hummelstown's median sale price per square foot at $175, up 3.5 percent year over year as of its June 2026 report, a steadier figure than either the average or median dollar amount because it accounts for the size difference between the two housing products.
- Watch days on market as a temperature check. Redfin's May 2026 data showed homes taking an average of 20 days to sell, compared to 5 days the year before. That slower pace suggests a bit more breathing room for buyers even as headline prices climb, which matters if you are trying to time an offer.
None of this means Hummelstown got cheaper or more expensive by some fixed amount this year. It means the town is small enough that a single number cannot describe it honestly. The real question is not "what is the average home price in Hummelstown," it is "what does a home like the one I want actually cost in the part of town where it sits."
A Couple of Questions Worth Asking Directly
Is Hummelstown's market cooling down or heating up? Both, depending on what you measure. Prices by most counts are still climbing, but the pace at which homes are selling has slowed from 5 days on market a year ago to 20 days as of May 2026. That is a market that remains competitive without the frantic urgency of the year before.
Should I trust the median or the average when comparing Hummelstown to another town? Neither one alone. The median tells you what a typical closing looked like, but in a town this size a typical closing can shift month to month based on which product happened to sell. The average tells you the dollar-weighted picture, but a single large sale can distort it. The honest answer comes from looking at both numbers side by side and asking which part of town they are actually describing.
Comparing towns on price alone will always miss the texture that makes one Hershey-corridor community feel different from the next.
