"With more competition on the market, the starting price matters more than ever," 2026 Columbus REALTORS® President Gloria Alonso Cannon said in the Central Ohio Housing Report for September 2026, released October 13. Inside Westerville city limits, starting prices are the very thing a buyer has to question this fall, because the headline numbers point two ways.
According to the Columbus REALTORS® Westerville Corp. market update for September 2026, homes for sale in the city rose from 47 to 67 year over year, a 42.6% increase. Homes that went under contract fell from 46 to 33, down 28.3%. More supply and fewer signed buyers usually cool prices. Yet the September median sale price rose 6.3% to $425,000, homes sold in a median 16 days, and sellers received 98.8% of their original list price.
The median and the contract count describe two different months. The median comes from deals buyers agreed to in late summer. The contract count shows what buyers did in September.
A September Closing Was Usually Priced in August
A sale that closes in September reflects a contract signed weeks earlier, and an offer written at that earlier mortgage rate. The contract count reflects what buyers decided during September itself. Those two months were not the same market.
Freddie Mac's weekly Primary Mortgage Market Survey shows how far the average 30-year fixed rate moved over that stretch:
- August 2026: steady between 6.65% and 6.69% every week
- September 3, 2026: 6.71%
- September 17, 2026: 6.95%
- September 24, 2026: 7.03%
- October 8 and October 15, 2026: 7.40%
Columbus REALTORS® tied the regional drop in contracts, down 12.7% across Central Ohio in September, to that climb, saying rising rates "prompted some buyers to pause." Westerville's contract drop was more than twice the regional figure. So September's 49 city closings, up 19.5% from a year earlier, mostly show demand left over from the summer. The 33 new contracts show demand at roughly 7%. By mid-October, a buyer writing an offer faces a rate about three-quarters of a point higher than the buyers whose closings produced the $425,000 median.
The 6.3% Gain Is Measured From a Soft Month
The year-over-year comparison carries a second distortion. In September 2025, Westerville's median was $399,900, well below the city's 2025 year-to-date median of $430,000. The September 2026 median of $425,000 is actually lower than the 2026 year-to-date median of $444,001, which rose only 3.3%.
Put another way, September 2026 was a cheaper month than most of 2026 so far. It only looks like a jump because September 2025 was cheaper still. The report itself warns that "percent changes are calculated using rounded figures and can sometimes look extreme due to small sample size." Forty-nine sales is a small sample. A few larger homes closing in one month can move the median sharply.
That appears to be what happened. The city's average sale price rose 13.0% in September 2026, to $441,371, while average price per square foot rose only 3.2%, to $233.69. When the average price rises about four times faster than the price per square foot, the homes that sold were mostly bigger. They weren't worth that much more per foot.
The Wider Westerville Area Shows the Cooling First
The pattern is clearer in a second Columbus REALTORS® report, the one for the Westerville City School District. That's a separate reporting area, not city limits. It spans Franklin and Delaware counties. According to the district, its boundaries take in all or part of the City of Westerville, the City of Columbus, Blendon, Genoa, Plain and Sharon townships, and the Village of Minerva Park. With roughly twice the city's sales, its figures are steadier, and they point the same way the falling contract count does.
| September 2026 | Westerville city | Westerville City School District area | Central Ohio |
|---|---|---|---|
| Median sale price | $425,000, +6.3% | $412,500, +7.1% | $334,250, +2.8% |
| Price per square foot | $233.69, +3.2% | $219.17, −2.6% | n/a |
| Days on market | 16, down from 17 | 27, up from 22 | 33, up from 30 |
| Share of original list price received | 98.8% | 97.0%, down from 99.5% | 96.3% |
| Months' supply | 1.6, up from 1.2 | 1.7, up from 1.6 | 2.6, up from 2.3 |
Across the district area, the median rose 7.1% while price per square foot fell 2.6%. That's the size effect again, and a stronger one. The median list price of new listings there jumped 14.7% to $430,000, so sellers are bringing larger or more ambitiously priced homes to market. Buyers are taking longer and paying less against those asking prices. A 2.5-point drop in the share of original list price received comes to about $10,000 on a $412,500 home.
Inside the city, sellers are still close to list. Across the wider area, the asking price has started to slip.
Why the City Core Holds Tighter
Westerville city still has only 1.6 months of supply, far below the 5 to 6 months Columbus REALTORS® describes as a balanced market. That tightness comes from geography. The City of Westerville's September 8, 2026 work-session presentation says only 5%, or 409 acres, of the city's 12.74 square miles remains developable greenfield without an active approved plan. Most of it sits in the far north along Cleveland Avenue and Polaris Parkway. The city states that future growth "must transition to redevelopment and infill."
The city's 64 E. Walnut Street project page shows how slow that path can be. The site formerly housed City of Westerville offices. City Council voted unanimously on June 2 to reject a sale agreement for its redevelopment, then held a community workshop on August 11 and a work session on September 8. The city's September presentation says there is "no current project" for the site, and it lists sale, conditions, developer selection and public process as steps still ahead.
So the 20 extra listings in Westerville this September are resale homes, existing houses whose owners chose this fall to sell. That limits how far city prices can fall, because no wave of new construction is waiting behind them. It also means that once a resale home sits unsold, the seller doesn't have a builder's incentives to compete with, only rate-sensitive buyers.
What This Means for a Fall Offer
For a buyer comparing Westerville with other suburbs, several practical points follow:
- Price the home, not the median. The $425,000 citywide figure reflects summer contracts and a shift toward bigger homes. Price per square foot from recent sales of similar homes nearby says more about what a specific house is worth.
- Treat days on market as a signal. In a city where the median home sold in 16 days in September 2026, a listing that has sat noticeably longer, especially one listed after rates moved past 7%, is more likely to have a seller open to negotiating.
- Expect the city and the wider Westerville area to behave differently. The district-area figures, with 27 days on market and 97.0% of original list price, describe a softer market than the city figures do. Homes just outside city limits may offer more room to negotiate.
- Read the tax line with its date in mind. Franklin and Delaware counties are both in the middle of 2026 property value updates. Franklin County reported in June that tentative residential values were up about 10% on average, while noting that a value increase does not mean the same percentage increase in taxes. The Delaware County Auditor says new tax amounts won't be available until mid-to-late December 2026, after November election results and tax rates are certified. The tax figure on a listing this fall therefore reflects pre-update values. For Delaware County owners, the online informal-review deadline is October 30, 2026.
The tax points above are general information, not tax or financial advice. Confirm how the updates affect a specific property with the county auditor or a qualified tax professional.
A Few Questions Buyers Ask
Is Westerville becoming a buyer's market? Not by the usual measure. At 1.6 months of supply in September 2026, the city remains well short of the 5 to 6 months Columbus REALTORS® associates with balance. The change is in direction. Supply is rising and signed contracts are falling, which gives buyers more time and room than they had in the summer.
Why do the city and school district reports show different medians? They cover different areas. The Westerville City School District area includes neighborhoods outside city limits, and it recorded 96 September closings compared with 49 inside the city. One figure can't stand in for the other.
When will October's numbers show the effect of 7.40% rates? Columbus REALTORS® published its September report on October 13, 2026. When the October report comes out, watch closed sales. Many of October's closings will come from September's smaller pool of contracts.
