Staying in communication with clients, team members, other agents, inspectors, appraisers, lenders, and everyone else involved in the real estate process is key to success. A second mobile number will help you sound more professional when clients call, no matter where you are.
Consider for a moment how your phone is currently being answered. Professional courtesy is quite often not the standard for many college students. An abrupt "Yeah!" could be listed among the more courteous greetings. The more outrageous remarks will often buy you a major black mark in the professionalism category—even if it was your roommate answering your phone and acting crazy. A simple "This is ____" is always a pleasant change for a college student call. Make the change today, before the next (or first) employer phone call. If you have a landline, you should also encourage your roommate to do the same.

When you’re closed for the holiday, it’s good to forgo your usual out-of-office greeting for a custom holiday message. Keep it cheery and brief, and be sure to let callers know when you’ll resume normal business operations.
When your small business is closed, ensure that your callers know that! If appropriate, you might want to reiterate your business hours to manage callback expectations.
