Mobile real estate listing company Smarter Agent has closed $6.2 million in an over-subscribed first round of funding. The round was led by private equity magnate Ira Lubert, who co-founded Lubert-Adler’s multi-billion dollar real estate fund, LLR Partners, Quaker Bio Ventures and Versa Capital. The funding will support the roll-out of Smarter Agent’s GPS real estate searches including a Homes for Sale application due to launch at the beginning of Spring. Smarter Agent has a service which lets people find houses for rent or sale near where they are when they make the enquiry—it launched on Sprint (NYSE: S) a year or so ago and gains subscription revenue though a monthly fee. It claims that over 25,000 people used the service over the summer and 35 percent placed calls to the agent/property owner, which is a good click-through level.
