About Gregory Karlson

Greg Karlson brings a wealth of knowledge and experience to the real estate landscape of Highlands County, where he has deep roots. A graduate of Lake Placid High School, Greg has dedicated decades to the listing and selling of properties in the Heartland area.

After earning a Bachelor of Science in Business Finance from Florida Southern College, Greg obtained his real estate license and began his career under the mentorship of esteemed professionals recognized by the MAI (Member Appraisal Institute) and CCIM (Certified Commercial Investment Member) designations. This foundation has equipped him with a strong understanding of both residential and commercial real estate.

In 2004, Greg established his own real estate office in Sebring, starting with a small team of four associates and $10 million in listings. Within a year, the office experienced remarkable growth, achieving $35 million in sales. Today, the firm boasts over 30 associates specializing in residential, commercial, agricultural real estate, and property management, including a dedicated division for residential rentals.

The synergy between Greg's real estate business and his wife Pamela’s law practice, Karlson Law Group, enhances the services offered to clients. Pamela's legal expertise provides invaluable support to both buyers and sellers navigating the complexities of real estate transactions.

In 2020, the firm achieved over $60 million in sales across commercial, agricultural, and residential properties. This momentum continued into 2021, with total sales volume exceeding $86 million, driven by an influx of individuals relocating from the Northeast in search of new opportunities in Florida.

With a dedicated team of over 30 agents, Greg Karlson is committed to helping clients realize their real estate aspirations and navigate the market with confidence.

If you need to reach working real estate agents in Highlands County, Florida, this list was built for you. Mortgage lenders, title companies, PropTech platforms, E&O insurers, continuing education providers, and real estate recruiters all rely on targeted agent data to drive pipeline — and a county-level list puts your message directly in front of the professionals most likely to respond, without paying to reach agents three counties away who will never send you a deal.

Whether you are launching a cold email sequence through a platform like Zap Contact (zapcontact.com) or another dedicated cold-email tool, running a direct mail drop, or building a LinkedIn matched audience, the foundation is the same: accurate, current contact data for licensed agents in your target market. This list includes {{AGENT_COUNT}} actively licensed Highlands County agents with verified email addresses, plus {{CELL_COUNT}} agents who also have cell phone numbers on file — giving you multiple channels from a single purchase.

Why Buy a Highlands County Real Estate Agent Email List From Dr Bill

Dr Bill has been selling real estate agent lists since 2005 and has delivered over 31,000 lists to lenders, vendors, and service providers across the country. Every record is sourced directly from the Florida state licensing board — not scraped from aggregator sites or cobbled together from outdated directories. New emails are added weekly, the full list is cleaned monthly, and the entire database is completely refreshed bi-annually, which is why Dr Bill can guarantee 96% deliverability — a standard most cheap data vendors cannot come close to matching.

Generic list sellers often bundle counties together or sell you a statewide file you have to filter yourself, and their data may not have been touched in over a year. With Dr Bill, you are buying a living dataset with a real deliverability guarantee behind it. If you buy a Highlands County real estate agent email list from a discount provider, you often get bounce rates that tank your sending reputation before your first campaign is even finished.

How to Use This Highlands County Agent List

Email outreach is the highest-volume use case — load the file directly into Zap Contact or a similar cold-email platform and launch segmented sequences by broker versus sales agent, which is a distinction included in the data. You can also use the list for direct mail, SMS campaigns using the included cell numbers, or upload it as a custom audience for LinkedIn advertising to reach these agents across channels simultaneously.

Segmenting by broker versus sales agent alone can double your response rates because the message that resonates with a team leader is completely different from what a solo agent needs to hear. The city and zip code fields also let you focus tightly on specific offices or neighborhoods within the county.

Why Highlands County, Florida Agent Data Matters

Highlands County covers a distinct market anchored by Sebring, Avon Park, and Lake Placid — communities with their own agent ecosystems that rarely overlap with agents working in Orlando or Tampa. With {{AGENT_COUNT}} licensed agents operating in this county, there is a real, reachable audience here, and no other vendor currently offers this list segmented down to the zip code level within Highlands County, which means you can target agents in a single zip without buying the entire county file.

Local targeting beats statewide blasts every time because relevance drives opens and opens drive responses. An agent in Sebring is not competing for the same clients as an agent in Sarasota, and your offer should reflect that. Highlands County-specific data lets you personalize your outreach by market, build credibility with local references, and avoid the noise of a 200,000-record statewide file where your message gets lost entirely.
