Many loan officers hand out their cell phone number. This is a way of selling themselves to potential clients and beginning a professional relationship.
Think through what you are going to say before you place the call. When men hear the beep, they often freeze up and forget what they wanted to say. If you want to be the go-to guy at work, then you have to exhibit competence on all levels. Don’t spoil your confident image by hemming and hawing and filling your messages with “uhhhhs,” and “ummmms.” If it’s a really important call, consider writing out what you want to say beforehand. If the person picks up, great, you now have some notes to remember what you wanted to talk about. If they don’t answer, you can leave a clear and concise message.

In an email, you may end by telling the contact what you want them to do next. In a voicemail, though, ending with something like, “Call me back,” or, “If I don’t hear from you, I’ll call next week,” can discourage the person from responding.
So, leave "Call me back when you get this," at the door, and try, "Talk to you soon," "Thanks for your time," or a good old-fashioned, "Have a great day."
