Join Gromadzki Real Estate — Florida's 100% commission real estate brokerage. $499 per closed deal, $0 monthly. Serving Casselberry and all of Seminole County.
Casselberry is part of the broader Orlando metro area — a market that combines tourism-economy stability with growing tech, healthcare, and professional-services employment. Transaction volume is reliably above Florida averages, and the buyer pool spans from short-term-rental investors to family relocations to retirees.
At Gromadzki Real Estate, the structure is straightforward: $499 per closed transaction. $0 monthly. $0 annual. You keep 100% of the commission on every closed deal in Casselberry or anywhere else in Florida. Full broker support, modern technology, and training are included.
Casselberry sits in the Orlando metro's mid-price band: the Seminole County median held near $400,000 in mid-2026, up 0.8% year over year (Redfin, mid-2026), while the ORRA five-county single-family median ran $451,922 (ORRA/Stellar MLS, June 2026). At the county number, a 3% side is roughly $12,000 gross. A 25% split brokerage skims $3,000 of that on every closing; a flat-fee brokerage like Gromadzki takes $499 and you keep the rest. In a Seminole County town built on 1970s–80s homes off Semoran Boulevard and US 17-92 — steady, financeable, entry-buyer inventory — that gap is the difference between a career that compounds and one that leaks.
Sources: Redfin Seminole County (median price, days on market, mid-2026); Orlando Regional REALTOR® Association / Stellar MLS (months of supply, June 2026); Florida Realtors/Stellar MLS statewide single-family (sale-to-list, May 2026). County and ORRA metro data are used as the anchor because Casselberry city-only medians swing month to month on a small, mixed sales sample.
Casselberry is a small, fully built-out city in central Seminole County, and the honest read on its market comes from county and metro data rather than the city's own thin monthly sample. As of mid-2026 the Seminole County median sat near $400,000, up about 0.8% year over year, with homes going under contract in a median 55 days (Redfin, mid-2026). Across the wider Orlando metro, ORRA reported a single-family median of $451,922 and an overall median of $416,308 in June 2026, up from $409,631 a year earlier — roughly a 1.6% annual gain (ORRA/Stellar MLS, June 2026). Supply has loosened to 4.1 months metro-wide, still under the six-month balance line but the softest it has been in years (ORRA, June 2026).
Why lean on county and metro figures? Because Casselberry's city-only median is genuinely noisy. In the same season, portals put it anywhere from about $348,899, up 2.7% (Zillow, June 2026) to roughly $359,000 (Broker One, July 2026) — a spread driven by how many small ranch homes versus larger lake-area properties happen to close that month, not by real price movement. Seminole County as a whole showed roughly 1,464 active listings and price cuts on 24.3% of them (MoveWithMomentum, 2026), a balanced, negotiation-friendly backdrop. For an agent, the takeaway is simple: price Casselberry off the county trend, not off last month's three closings on your street.
Casselberry's whole value proposition is location. State Road 436 (Semoran Boulevard) and US 17-92 cut straight through the city, feeding directly into I-4 and the 417 (Central Florida GreeneWay), which is why a buyer priced out of Winter Park or Maitland can still land a sub-$400k home here and be in downtown Orlando in twenty-odd minutes. That corridor is the market. Homes in the older neighborhoods off Semoran and US 17-92 — the entry-level ranches and split-plans built in the 1970s and 80s — move on affordability and commute, and they are the bread-and-butter listings a Casselberry agent takes.
The lakes give the city its second layer. Lake Concord anchors the civic core near City Hall and the Casselberry Art House, Secret Lake and its park sit just west, and the Red Bug Lake Road corridor to the east links Casselberry toward Winter Springs and Oviedo, with Red Bug Lake Park drawing weekend traffic. Homes with lake frontage or golf-course lots (the old Casselberry Golf Club area) carry a premium and a different buyer than the commuter tract homes — which means two distinct pricing playbooks inside one small city. Nearby SunRail stations in Altamonte Springs and Winter Park add a rail commute option that a well-informed agent should be quoting to Orlando-bound buyers.
The engine under Casselberry demand is Seminole County Public Schools, one of Florida's higher-rated districts, paired with a price point that undercuts its neighbors. Buyers who cannot reach Winter Park, Maitland, or Lake Mary — where medians run well above the metro's $451,922 single-family figure (ORRA/Stellar MLS, June 2026) — routinely trade down into Casselberry to stay inside the same county school system. That "same schools, lower price" story is the single most repeatable listing pitch in this market, and it holds even as metro supply loosens to 4.1 months (ORRA, June 2026).
Casselberry also runs heavy on renters and investors. With a Seminole County median near $400,000 (Redfin, mid-2026) and typical rents around $1,882 a month (MoveWithMomentum, 2026), the older Semoran-corridor homes and the condo and townhome clusters off Red Bug Lake Road pencil for buy-and-hold investors and small landlords in a way beachfront markets no longer do. That means a Casselberry agent works cash investor closings, first-time FHA buyers, and move-down families in the same week. Statewide, single-family sellers received a median 96% of original list price in May 2026 (Florida Realtors/Stellar MLS) — so sharp pricing and real negotiation, not a hot-market coast, are what actually close deals here.
Run the math at Casselberry's real price point. On a home at the Seminole County median of about $400,000 (Redfin, mid-2026), a 3% side grosses roughly $12,000. A 25% split brokerage keeps $3,000 of that on every single closing; a 20% split keeps $2,400 — before monthly desk fees, tech fees, and franchise dues. At Gromadzki, that same closing costs a flat $499, so you keep about $11,500 instead of $9,000.
Scale it to a working year. An agent closing ten sides at the $400,000 county median (Redfin, mid-2026) grosses about $120,000 at 3% per side. A 25% split hands the brokerage roughly $30,000 of that; at Gromadzki those ten closings cost $4,990 total, leaving about $25,000 more in the agent's pocket every year. At the ORRA metro single-family median of $451,922 (ORRA/Stellar MLS, June 2026) the gap only widens. In an affordability-driven market where you earn your keep on volume and negotiation — not on a single trophy sale — a percentage split quietly taxes the exact work Casselberry rewards. A flat fee doesn't.
One simple structure, statewide. The same $499 per closed deal applies to every Florida city, including Casselberry.
