As a real estate professional, you're always on the go. Whether showing homes and apartments to a prospective client or staging a home for sale, it's likely that you're out of the office quite often. Anyone in the industry knows that, out of the office is a good place to be. Unfortunately, it makes staying professional just a little bit harder. What happens when you're working with one client and another one calls? Most likely, you send that call to your voicemail box, but what does your voicemail greeting say? What should voicemail messages include? If you're voicemail isn't offering the right information, you might lose a sale.
Whether you are trying to be funny or want your friends to know your favourite song, chances are your Placement Consultant or Hiring Manager will not be impressed by an unprofessional voicemail. You should ensure that you record a professional voicemail message (with no background noise) such as, “Hi, you’ve reached [say your full name]. I’m sorry I missed your call. Please leave your name, number and a brief message after the tone and I will call you back as soon as possible.”
