Market temperature
What's this?Compared with Mercer County's own history
50 = typical for Mercer in September
Typical, leaning cool
Each factor compares this county with its own history (Sep 2016–2019, 2023–2025). 50 = typical for this county at this time of year (the mid-line on each bar). Under 40 = cooler than usual, over 60 = hotter than usual. When the factors pull hard in opposite directions, a middling score means they're cancelling out, so it's labeled mixed signals. Affordability is shown for context and isn't part of the score.

Typical rent is Zillow's Observed Rent Index for Sep 2026 (asking rent across all home types); “–” means Zillow doesn't publish one for that town.

What this means for you
What this month's numbers mean for buyers, sellers, and investors in Mercer County.
For buyers
Some Room to Negotiate- →Supply is tight (3.6 months of supply), so this counts as a seller's market, but a mild one: homes aren't being bid up over asking, so buyers have some room to negotiate. I'd still get pre-approved before you tour so you can act when the right house comes up.
- →Homes are selling at about the same pace as last year, with a median of 48 days on market.
- →Homes are selling right around asking (100.1%). Well-priced homes still draw interest, but there's less pressure to bid over list.
For sellers
Price to Market- →Median prices are down 3.5% from a year ago. An overpriced home will sit, so I'd price at market from day one to draw real interest.
- →Supply is tight (3.6 months of supply), but buyers are price-sensitive right now: homes are selling around asking and median prices have dipped. I'd prep the house fully and price to the latest sales of similar homes.
- →Spring (March–May) typically brings peak buyer traffic in this county. It's better to list fully prepared than to rush to catch it.
For investors
Best Rent-to-Price of the 12- →Median prices are down 3.5% year-over-year in Mercer County. I'd underwrite on current rents rather than past appreciation and look for sellers who've already cut their price.
- →Typical rent here is about $2,523/month (Zillow, Sep 2026, up 2.4% YoY). At the ~$434K median price, that's a gross yield of 7.0% and an estimated cap rate around 2.5% after property taxes and 30% of rent for other costs, before financing. That's 3rd of the 12 counties I track on estimated cap rate.
- →With a ~$434K median entry price, Mercer County comes closer to cash flow than most. Financed at today's rates, a purchase here still needs a large down payment or a below-median price to cover its costs.
