Union County PA Real Estate Market Report: June 2026

A 17.7 percent increase in median sale prices is not a number that shows up in a healthy, balanced market. It signals something more specific: a market where demand has outrun supply long enough that buyers have had no real choice but to move the price ceiling upward. That is where Union County stands as of June 2026, and the rest of the data confirms it.

The median sale price in Union County reached $372,500 this month. The median list price was $389,500. Homes sold in a median of 18 days, and there are only 54 active listings countywide. Taken individually, each of those numbers tells a piece of the story. Taken together, they describe a market that remains firmly in seller territory with little near-term relief in sight for buyers.

Sellers in Union County are receiving an average of 96.8 cents for every dollar they list at. That list-to-sale ratio reflects how much negotiating room currently exists in this market, which is to say, not much. When that figure is close to 100 percent, it tells you that buyers are not finding leverage at the offer table. Concessions, price reductions, and extended contingency periods are the exception here, not the rule. Sellers who price reasonably are not waiting long for results, and they are not walking away with much less than they asked.

The 18-day median days on market reinforces that picture. Eighteen days is not an unusually long runway for a property to sit before going under contract. In most balanced markets, particularly in rural and semi-rural Central Pennsylvania communities like those found throughout Union County, you would expect homes to take longer to sell depending on price point, condition, and location. The fact that the median sits at 18 days suggests that well-priced homes are routinely receiving attention within the first two to three weeks, and that waiting for the right buyer is not costing sellers much time.

Because we do not have a full three-year historical data set for Union County specifically during the April reporting period, some of the comparisons we would typically draw in a Mid Penn Market Pulse analysis are not available in this cycle. What we can say is that the current conditions as a whole are consistent with what a tighter-than-normal market looks like in practice: low inventory, strong price growth, fast sales, and minimal negotiating room for buyers. Those are not conditions that emerge from a single good month. They build over time, and a 17.7 percent price increase versus the prior period suggests they have been building.

With only 54 active listings across all of Union County, the available inventory picture is stark. Union County encompasses communities including Lewisburg, New Berlin, Mifflinburg, Hartleton, Hartley Township, and the surrounding rural townships. It is also home to Bucknell University, Evangelical Community Hospital, and a number of employers that draw both long-term residents and relocating professionals. Fifty-four listings spread across that geography and across all price points, property types, and conditions means that buyers are making decisions from a limited shelf of options.

The 2.08 months of supply reinforces this. A balanced market typically carries somewhere between four and six months of supply. At 2.08 months, Union County has less than half of what would be considered a neutral inventory level. That imbalance is what gives sellers pricing power, and it is what makes the 17.7 percent price increase less surprising in context. When buyers have few alternatives, competition for the available homes increases, and prices respond accordingly.

What the numbers are telling collectively is a story about constrained supply meeting persistent demand. Union County’s combination of access to Route 15 and Interstate 80, proximity to Williamsport, the Susquehanna Valley corridor, and the broader Lewisburg area’s community character continues to attract buyers from within and outside the region. Lewisburg in particular has a downtown district and a regional draw that is not typical of similarly sized boroughs in Central Pennsylvania, and that draws both buyer interest and price pressure into the market.

For buyers active in Union County right now, the market requires a specific kind of preparation. This is not a market where extended deliberation is rewarded. Homes priced at or near market value are moving in roughly two and a half weeks on average, which means that a buyer who waits for a second showing, delays a pre-approval, or spends too long negotiating price risks losing the property entirely. Coming to the market pre-approved and having a clear understanding of your acceptable price range before you begin touring homes is genuinely important in conditions like these.

Buyers should also calibrate their expectations around concessions. A 96.8 percent list-to-sale ratio tells you that most sellers are not motivated to make significant price adjustments, cover closing costs generously, or accommodate long inspection periods as a matter of course. That does not mean negotiation is impossible. It means buyers should prioritize homes where they can offer competitive terms rather than expecting the seller’s position to soften significantly at the table.

The good news for buyers is that 54 active listings, while below a balanced level, is not zero. There are homes available, and buyers who are patient and strategic can find properties that meet their needs. Working with a broker who tracks new listings closely and understands which properties in the county have been sitting longer than average can open doors that a simple online search might not.

For sellers in Union County, the April data is straightforwardly favorable. A 17.7 percent price increase compared to the prior period suggests that values have moved meaningfully, which matters both for what sellers can expect to net and for how they should think about timing. If you have been considering selling but waiting for the right moment, the current inventory environment is not creating additional competition for you. With only 54 active listings, your home will have a relatively clear field when it enters the market.

Sellers should also note that 18 days on market suggests correctly priced homes are not languishing. If you overprice relative to recent comparable sales, you will see that number stretch, and a longer days-on-market history can work against you with buyers who assume something is wrong. Pricing at or just below peak comparable values tends to generate more initial activity, which in a market this tight can produce multiple-offer situations that ultimately achieve a stronger sale price than aggressive initial pricing alone.

The one dynamic worth watching carefully in a market like this is the relationship between the list price and the sale price. The $17,000 gap between the median list price and the median sale price suggests some softening from the list, even in a seller-favorable environment. That gap is worth monitoring. If it begins to widen, it could be an early signal that buyers are starting to push back on pricing expectations, even if overall conditions remain tight.

The broader takeaway from Union County’s June 2026 data is that this market has not loosened meaningfully. Prices are up substantially, inventory remains well below a balanced level, and homes are selling quickly relative to what most Central Pennsylvania communities would consider a normal pace. Buyers are competing for a limited number of homes, and sellers hold the stronger hand at the negotiating table. That dynamic does not reverse quickly, and nothing in the current data suggests it is in the process of doing so.
