Best Realtor in Sunbury, Ohio: Buying on Delaware County's Growth Edge

Sunbury is a town you can watch change in real time. It spent most of its history as a small village around a classic town square, and in 2026 it officially became a city. That does not happen by accident. It happens because people keep moving here, and the question every buyer should be asking is whether they are arriving early or late.

I think the answer is nuanced, and it depends entirely on what you want the town to be. Let me lay out the growth, the numbers, and the trade-offs, and then what the right agent does with all three.

Why is Sunbury, Ohio growing so fast?

Sunbury sits in Delaware County, one of Ohio's fastest-growing counties, up near the meeting of I-71 and US 36/SR 37 on the northeast edge of the Columbus metro. By population count it has been among the fastest-growing communities in the state for years. Reported figures put the population above 11,000 and up roughly two-thirds since the 2020 census. New subdivisions, new retail, new school enrollment, and the I-71/Sunbury Parkway interchange project meant to unclog the connection to everything.

That is the setting. A place adding rooftops faster than almost anywhere in Ohio, still close enough to a classic square to remember what it was. For a buyer, that motion is the opportunity and the risk in the same sentence.

Why does Sunbury's town square still matter?

It would be easy to sell Sunbury as nothing but new subdivisions, and that would sell it short. The town grew up around a real village square, the kind of nineteenth-century core that most exurbs never had and cannot fake. That old center is why Sunbury feels like a place and not just a collection of cul-de-sacs off a highway ramp.

I point this out because it changes how you should shop here. There are effectively two Sunburys competing for the same buyer: the established homes near the square with mature trees and walkability, and the new-construction rings pushing out toward the interstate with more space and less history. They are different products at different prices with different resale stories, and the listing photos will not tell you which one you are standing in. A buyer who wants the square-adjacent feel and a buyer who wants a half-acre and a three-car garage are shopping in the same ZIP for two different towns.

What do homes cost in Sunbury, Ohio?

Per Redfin, the 43074 ZIP that covers Sunbury and its surrounding build-out carries a median sale price around $545,000, up about 6 percent year over year, at roughly $217 per square foot, with homes averaging about 42 days on market in a market Redfin rates somewhat competitive. (The incorporated-city sample is thinner and swings more, which is why the ZIP is the steadier read.)

Look at that price per square foot. $217 is below the inner northwest suburbs, where Worthington runs $257 and Dublin sits higher still. That gap is the whole reason to be out here. You are trading proximity for space, and the math rewards the trade with more house and more land per dollar than the bid-up corridor closer to downtown. Sunbury is where land is still part of the deal.

How are Sunbury's schools rated?

Here is where I will be plain, because a lot of Sunbury marketing is not.

Big Walnut High School grades B on Niche's 2026 rankings, ranked #7 among Delaware County public high schools and #189 in Ohio, with a 93 percent graduation rate across roughly 1,300 students. That is a solid, above-average district. It is not the top-of-the-state, five-star Olentangy operation a few exits west, and you are not paying Olentangy prices for it either.

That is the honest frame. If your top priority is a nationally ranked district, you would look at the Olentangy towns and pay for the privilege. If your priority is land, space, and value with a good district attached, Big Walnut is exactly that. As always, confirm the assigned school for the specific address before you write, because in a fast-growing area boundaries and buildings change.

What are the trade-offs of buying in Sunbury?

Growth cuts both ways, and a good agent tells you the second half:

• It is farther out. The commute to downtown Columbus is real, and US 36/37 plus the I-71 ramps carry the congestion of a corridor still catching up to its own growth. Drive it at rush hour before you fall for a floor plan.
• It is new-build heavy. A large share of what sells here is recent construction, which is a strength if you want turnkey and a caution if you assume newer means problem-free. Build quality varies by builder and by phase.
• The resale market is thinner and slower. Those 42 days are not the two-week feeding frenzy of the inner suburbs. That is not a flaw. For a buyer it is leverage, if your agent knows how to use it.
• You are buying a moving target. The town you tour in 2026 is not the town you will live in by 2030. That is a feature if you like the trajectory and a risk if you assumed it would stay quiet.

What does the best realtor in Sunbury actually do?

A fast-growing exurb rewards a specific skill set. Whoever you hire should show you:

1. New construction fluency. Builder contracts are not resale contracts. Deposits, upgrade pricing, warranty terms, and the fact that the builder's rep works for the builder. You want your own representation at that table. The full buy-side standard is here: what a great buyer's agent actually does.
2. A read on which developments hold. In a town adding subdivisions this fast, not every phase ages the same. Lot position, build quality, and how a development finishes out all move resale value. That read is worth more here than in a settled suburb.
3. Using the clock as leverage. Longer market times and a somewhat cooler pace mean a buyer often has room to negotiate that the inner corridor does not offer. An agent who treats every listing like a bidding war leaves your money on the table.
4. Marketing that fights the distance. If you are selling, you are competing for buyers whose eyes default to the closer, more famous suburbs. That is a solvable marketing problem, and the answer is not phone photos. Here is the standard I hold my own listings to: what a great listing agent actually does.

My Honest Pitch

I work the whole Columbus and Delaware County map from a Westerville base, and Sunbury is a town I put in front of buyers who want space and value and are willing to trade a longer commute for it. I came up in residential construction, which matters in a new-build market, because I can read a builder's work and a builder's contract, and both of those decide whether the deal is as good as it looks.
