Residential Single Family – Our residential single family services connect buyers with sellers every day, and we do it with professionalism and a total dedication to our clients. This property type is the majority of our market transactions, but by far not the only one in which we have expertise.
Condominiums – While condominiums are residential, they’re a very different market focus, and we have experts in evaluating condos and helping buyers and sellers to cope with the special financing and homeowner concerns for this property type.
Multi–family – Investors are great clients for RealNet Brokerage. Multi–family properties are a very unique market. The detailed return on investment and valuation calculations investors need to evaluate properties for rental are second nature to us.
Commercial – Whether it’s a shopping mall, a small office building or a restaurant space, we’re commercial property specialists. Contact us for your commercial property needs in the Tampa Bay Area
Vacant Land – Land is a very special property class. It’s relatively easy to show a gourmet cook a wonderful commercial kitchen in a home and see their eyes light up. It’s more of a challenge to help a buyer or seller to realize the potential in a piece of land.
Residential and Commercial Property Management- Services include back ground and credit checks, tenant placement, move in and move out inspections, rent collection and evictions.
Specialized Services- Assistance to International E-2 Visa Investors, 1031 Exchanges, Reverse Mortgage Sales, Business Sales, Estate and Divorce real estate transactions, REO’S, Short Sales and Distressed Properties.

After several years of moving back and forth between Milwaukee, WI and Florida, Dan and his family have decided to take the final plunge and make there dreams come true right here in the Tampa Bay Area.
When the family finally settled in, Dan knew he wanted to follow his passion into his next career in life as a Florida Realtor. Over the years making several moves and several purchasing several he found that there are major gaps in service and relationship building that are missing in most transactions. With Dan’s experience and background he knew this would be a natural fit to make the home buying experience less stressful for other families looking to move into the area.
Coming from a strong background of Hospitality and Electrical Construction, and Real Estate Investing… this seemed like the perfect fit to Dan. “It just seemed like a really good fit to use my construction experience for home buyers. I understand where Buyers are at when they are moving & relocating to make that transition to the area.”
This strong focus on the personal connection has helped to make Dan a popular choice among home buyers. In Florida, there are so many realtors it can be hard to know how to choose the right one. With Dan’s attention to detail and passion for service, he is committed to using his experience to help people find their dream of the Florida Life.
