Capitalization.  

There is something called Active Listening.  Several commenters have talked of listening, but how does the client know they were heard?  Active Listening.  To do this, do as Richie Alan Naggar said and repeat what you heard.  You don't need to repeat every word, and not as faithfully as a mimic, but don't change the words a lot or they won't seem like the speaker's.

If client says something, and hears the point being repeated by you, they will feel heard, and it builds trust.  If you then follow through with whatever was said, you will create a fan.

ROFL - nice one Amanda and Jared Christiansen !

Understand that we've been given 2 ears and 1 mouth for a reason!  Also, those 2 eyes we've been given will observe the secrets of the soul !

Profile pics are helpful in building trust.

learn how to LISTEN.....

The most important skill is being able to produce a grammatical and properly punctuated written communication.

Listen 

Abby, People confuse talking or writing with communicating.  What we say, how we say it, why we say it and when we say it all matter. What the client is wanting to hear, needing to hear, able to hear all matter.  Communicating EFFECTIVELY is a skill, it must be learned, developed and not assumed.

#1. You need to be able to smile, "I want to meet you."

#2. You need to write in a fashion you can not be misunderstood.

#3. Effective communication is not about transmitting data but collecting data.

#4. Be your genuine self. Limps, scars and all. When you are at home in your skin others will trust you. That is the goal of communication. Read that again.

I once signed someone while holding a donut.  I was accused of talking with food in my mouth.

Basic manners.

These skills are mandatory for success.

Carol Wilson points out an important one.

I believe all licensees should have very good communication skills and be able to answer their phone, return emails and text messages quickly!

All - verbal and writing skills, as well as recognizing non-verbal signals.

All of them

Good skills

 Press 1 for English.

You need to be able to communicate with a wide variety of people on many different levels and in many different ways...texts, email, on the phone, in person. You get the idea. 

Ability to communicate effectively.

Listening to what they are saying and asking qualifying questions.

Good ones.

They should answer the phone when clients call and/or return calls in a timely manner. It really helps close deals faster.

abby tiscareno I would say a top communication should be the skill of negotiating. Your clients wll be pleased with your expertise.

It depends on the target audience.

Great ones, verbal and written, and know how to listen!

LISTEN....then repeat

They should be able to listen to what others are saying abby tiscareno, because what 'they think' may not be correct, and really 'hearing someone' is very important!  Best of Luck!!
