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.
