The headline

Prosper's median sale price came in at $702,000, down 18.7% year-over-year. Median days on market reached 70 days, up 8 days from last September. There were 335 active listings, up 21.8%, and 38 sold listings, up 18.8% compared to a year ago.

September 2026 metric	Reported value	Change from September 2025
Median sale price	$702,000	Down 18.7%
Median days on market	70 days	Up 8 days
Active listings	335	Up 21.8%
Sold listings	38	Up 18.8%

Put plainly: buyers have more resale homes to consider than they did a year ago, and homes are taking longer to sell. At the same time, more sales closed than last September. That's a market with ongoing activity, but one where pricing, condition, and the competition deserve a close look.

What changed from August

In August's report, the median price was $760,000, median days on market were 57, active listings totaled 335, and sold listings totaled 43. September's median price was lower, the median selling timeline was longer, active inventory was unchanged, and five fewer homes sold.

That month-to-month comparison is separate from the year-over-year changes above: September sales were lower than August's, but higher than September 2025's.

A lower median sale price does not mean every Prosper home lost 18.7% of its value. The median is the midpoint of the homes that sold, and it can change with the mix of price ranges, home sizes, and neighborhoods represented in those sales. With 38 closings in the report, individual properties should still be evaluated against recent comparable sales.

What buyers are seeing

• More options to compare. Active listings are up 21.8% from last September. Take time to weigh location, layout, condition, and total monthly costs rather than focusing only on the asking price.
• A longer typical selling timeline. A 70-day median suggests more breathing room across the resale market, but it isn't a promise that a particular home will remain available. A well-positioned listing may still attract interest quickly.
• A reason to discuss price and terms. More inventory and longer selling times can create negotiating opportunities. Recent comparable sales, listing history, and seller circumstances should guide any request for a price adjustment, closing-cost credit, or repair concession.
• Keep resale and new construction separate. These figures cover single-family resale homes, not builder inventory. If you're comparing a resale home with new construction, review the full price, incentives, taxes, and move-in timing for each option.

Builders are competing with resale sellers

One of the clearest shifts in September's market is who resale homes are actually up against. New-construction communities aren't simply adding inventory; builders are competing directly with sellers on price and incentives. Across Prosper and nearby areas, builders are adjusting prices and offering incentives such as mortgage rate buydowns, closing-cost help, and included upgrades or design-center allowances to make a new home's monthly payment and total cost more attractive than a comparable resale.

That changes the comparison for both sides of the transaction:

• For buyers, the question isn't only "resale or new build?" It's which option costs less over the first several years. A rate buydown can lower a monthly payment today, while an older resale may already have upgrades the builder would charge for. Run the numbers on price, financing, taxes, insurance, HOA fees, and the incentives you'd actually use before deciding.
• For sellers, a buyer touring your home may also be touring a builder's model down the road with a bought-down rate and a package of upgrades included. That doesn't mean you can't win the sale, but it does mean price, condition, and marketing need to be sharp enough to justify a resale over a fully incentivized new build.

Incentives change quickly, and what a builder offers in September may not be available in November. If you're weighing a new home, ask for the incentive in writing and confirm how long it holds; if you're selling, tell me which communities your buyers are comparing against and I'll factor that competition into your pricing conversation.

What sellers should know

• Price to the homes competing with yours today. Last year's sale prices are context, not a substitute for recent neighborhood comparables and current listings. A home valuation can help put the town-wide numbers in perspective.
• Plan for a realistic timeline. The 70-day median is eight days longer than a year ago. Build flexibility into your moving plans and review showing activity and feedback as your listing progresses.
• Presentation and marketing matter. With more resale listings competing for attention, clear photography, thoughtful preparation, and a strong marketing plan help buyers understand your home's value.
• Your competition may be a builder, not a neighbor. Rate buydowns and upgrade packages at nearby new-construction communities pull buyers away from resales at the same price point. If a comparable new home is offering incentives, your pricing, condition, and staging have to make the resale the easier decision.
• Sales are still happening. The 38 sold listings represent an 18.8% increase from last September. The goal isn't to chase every headline; it's to position your home well for the buyers shopping your price range.

What I'm watching

I'll be watching whether the longer selling timeline continues into fall, whether resale inventory stays near September's level, and whether builder incentives such as rate buydowns and upgrade packages keep expanding. The combination of more listings and more closings year-over-year is worth tracking, especially alongside the mix of homes that sell each month.

For now, September's takeaway is straightforward: buyers have choices, sellers need a clear pricing and presentation strategy, and a neighborhood-level comparison matters more than a town-wide median alone.
