If you are an agent working for a well-established real estate
brand; they ought to have their own mobile app. If that can be
branded with your own information it may be a neat tool to
show customers and keep them searching.
In person networking takes 'mobile' literally. Get out there and
mingle at events and do business lunches at least a couple
times a week. Just beware of all the small travel and
entertainment expenses. They may be great tax write-offs, but
only if you are generating real income to count it against.
