When people search for a “top real estate agent in Catonsville,” they usually see rankings based on total volume or total transactions. The problem? Those rankings often include a lot of business done outside of Catonsville.
If you live in 21228, the only number that really matters is this:
What percentage of an agent’s transactions actually happen in Catonsville?
Below is a ranking of the top 10 agents based solely on the percentage of their transactions that occurred in the 21228 zip code in 2025. No volume hype. No countywide padding. Just focus.

Why This Metric Matters
Catonsville is not interchangeable with the rest of Baltimore County.
Pricing a house on Edmondson Avenue, Academy Heights, Westview Park, or near Frederick Road is different from pricing a house in Ellicott City, Towson, or Columbia. Buyer expectations, renovation payback, days on market, and even offer strategy change block by block here.
An agent who does most of their business elsewhere may be very successful, but they are still a visitor in Catonsville.
A local agent:
- Knows which renovations actually move the needle in 21228
- Understands how Catonsville buyers think and negotiate
- Prices homes based on real neighborhood demand, not countywide averages
- Anticipates inspection issues common to Catonsville housing stock
That local knowledge only comes from repeated, hands-on experience in this zip code.
A Note on Matt Totaro and Catonsville Living
At the top of this list is Matt Totaro, with 100% of his transactions for 2025 occurring in the 21228 zip code. That number is not an accident.
Matt’s business is built entirely around Catonsville Living, a brand and platform dedicated exclusively to Catonsville, Maryland. From neighborhood-by-neighborhood videos and weekly market reports to hands-on renovation guidance and pricing strategy, the focus is singular: helping Catonsville homeowners and buyers make better decisions in this market.
Rather than spreading business across multiple towns or chasing volume in adjacent areas, Matt works only in Catonsville. That concentration shows up in how homes are prepared, priced, marketed, and negotiated—and ultimately in results that reflect real, street-level knowledge of 21228.
The Bigger Takeaway
Several well-known, high-producing agents appear on this list with relatively low percentages of Catonsville transactions. That doesn’t mean they aren’t successful. It means most of their business happens somewhere else.
If you are buying or selling in Catonsville, that distinction matters.
When 70%, 80%, or 90% of an agent’s work is outside of 21228, Catonsville is not their primary market. It’s a side market.
And your home is not a side project.
