Best Time to Buy or Sell a House by County in the Philadelphia Region

If you're trying to decide whether to buy or sell a home this year, timing probably feels like one more variable working against you. You don't want to buy right before competition spikes, or list your home during a stretch when buyers hold all the leverage. And if you're weighing options across Bucks, Chester, Delaware, Montgomery, or Philadelphia County, you've probably noticed that what's true in one county doesn't always hold in the next.

At Premier Home Team, we help buyers and sellers across all five counties in the Philadelphia region every day, so one of the questions we hear most often is simple: “Is now a good time to buy or sell?” To answer it with more than a gut feeling, we analyzed three years of monthly market data from Reventure, covering 2023 through mid-2026, for each county.

Below, you'll find the best month to buy and the best month to sell in your county, along with the data behind each recommendation, so you can time your move with real numbers instead of a guess.

Here's the quick answer before we get into the data:

Looking for a broader explanation of why buyers often find more negotiating power in the fall? Our guide to When Is the Best Time of Year to Get a Good Deal on a Home? explains the seasonal trends behind inventory, competition, and pricing.

How We Determined the Best Months to Buy and Sell

Every local market follows its own seasonal trends. Using several years of monthly listing data from Reventure, we analyzed Philadelphia, Delaware, Chester, Montgomery, and Bucks counties to identify the months that have historically favored buyers and sellers.

Our analysis is based primarily on data from 2023 through June 2026. Because 2026 is only partial-year data, averages for July through December use data from 2023 through 2025. We averaged days on market, inventory levels, and price reductions for each calendar month to identify the periods that consistently offered buyers more negotiating power or sellers stronger demand.

Data note: these figures reflect data current through June 2026. We'll refresh this analysis annually as new market data becomes available.

These findings identify historical patterns, not guarantees. Individual home prices and selling timelines are also influenced by mortgage rates, local inventory, neighborhood demand, home condition, and broader economic conditions.

Philadelphia County

Best Month to Buy

October is strongest for Philadelphia County buyers. Price cuts average 27.7%, the highest of any month, and inventory peaks at an average of 4,593 homes, the most available all year. Homes also sit for an average of 56 days, giving buyers more selection and more room to negotiate. Taken together, those trends give buyers more choices and more negotiating leverage than any other month we analysed.

Best Month to Sell

April is the fastest month to sell, with days on market averaging just 48.8 and price cuts holding at a modest 23.3%. New listings also surge to an average of 2,054 in April, yet homes continue selling faster than in any other month. That suggests buyer demand is keeping pace with the wave of spring supply, creating favorable conditions for sellers.

Delaware County

Best Month to Buy

September brings the deepest price cuts in Delaware County, averaging 22.5%, with inventory climbing to 715 homes, close to the yearly peak of 732 in October. Days on market average 38.3, giving buyers more room to negotiate than the spring rush allows. Combined, these trends point to more room for buyers to negotiate than the spring market allows.

Best Month to Sell

May is fastest, with days on market dropping to an average of 29.5 and price cuts staying moderate at 15.1%. New listings climb to an average of 659 in May, and homes still move quickly despite the added supply. This data suggests that demand is keeping pace with the added supply, a favorable sign for sellers.

Chester County

Best Month to Buy

September is strongest for buyers, with price cuts averaging 18.6%, the highest of the year, and days on market stretching to 39.3. Inventory is also building toward its yearly high, averaging 658 homes and continuing to climb into October. Looking across the three metrics, those trends suggest buyers have more leverage and more time to negotiate than during the spring rush.

Best Month to Sell

May is the fastest to sell, with days on market averaging just 29.0 and price cuts staying relatively low at 13.3%. New listings reach an average of 668 in May, and homes still move quickly despite that added supply. That indicates that buyer demand is strong enough to absorb the added supply quickly, a favorable sign for sellers.

Montgomery County

Best Month to Buy

November brings the deepest price cuts in Montgomery County, averaging 20.0%, with days on market stretching to 41.0, the longest stretch outside the slow winter months. Inventory stays high at an average of 1,006 homes, nearly matching the yearly peak. When viewed together, those conditions suggest buyers have more negotiating leverage in November than at any other point outside of the slow winter months.

Best Month to Sell

May is fastest, with days on market averaging just 29.5 and price cuts contained at 13.7%. New listings peak at an average of 978 in May, and the quick pace of sales shows buyers absorbing that supply as fast as it comes on the market. That suggests buyer demand is absorbing new supply about as fast as it arrives, a favorable sign for sellers.

Bucks County

Best Month to Buy

October brings the deepest price cuts in Bucks County, averaging 18.1%, with inventory reaching an average of 724 homes, the yearly peak. Days on market average 37.3, longer than the spring and early summer months, giving buyers a wider selection. Overall, those trends suggest buyers have wider selection and more negotiating leverage than at any other point in the year.

Best Month to Sell

May is fastest, with days on market averaging just 29.0 and price cuts staying moderate at 14.7%. New listings climbed to an average of 712 in May, and the fast pace of sales shows demand strong enough to absorb that new supply quickly. That points to demand that is strong enough to absorb the new supply quickly, a favorable condition for sellers.

Should You Wait for the "Best" Month?

Probably not. While our analysis found months that historically favored buyers and sellers, waiting several months isn't always the best financial decision. Mortgage rates, inventory, your personal timeline, and the home you find often have a much bigger impact than trying to perfectly time the market.

What These Seasonal Trends Mean for Buyers and Sellers

The data makes one thing clear: there's no single best month to buy or sell across the Philadelphia region. Timing depends on which county you're in, and the numbers show real swings in inventory, competition, and negotiating power from month to month.

That's the challenge if you've been trying to plan a move around national headlines or general advice that doesn't account for your specific market. What works in Montgomery County in November may not apply in Bucks or Philadelphia, and guessing wrong can mean paying more than you should, or listing into a slower stretch than necessary.

Your next step is to look at what's happening in your target area right now, not just the seasonal averages. Pairing these historical trends with current inventory and pricing in your specific zip code gives you a much clearer picture of when to move. If you're wondering whether the "best" month automatically means every other month is a bad time to buy, your next step is reading Is There a Worst Time of Year to Buy a Home? It explains when timing matters most, and when other factors like inventory, interest rates, and your personal situation are more important than the calendar.

At Premier Home Team, our team tracks these market trends across Bucks, Chester, Delaware, Montgomery, and Philadelphia counties year-round. Seasonal trends give you an edge, but they shouldn't decide for you. The best time to buy or sell is when market conditions and your personal goals align. Understanding both gives you the confidence to move without relying on guesswork. If you want a breakdown of what's happening in your specific area right now, reach out and we'll walk you through the current stats for your target zip code.
