Go into every negotiation looking for solutions - be a problem solver, not a problem creator - strive for a win / win deal and not just a win for your customer - use a give get strategy - think outside the box.

Leave your ego out of the negotiation.

I learned a term years ago in a negotiation book...I use it with my clients..."what is your best alternative to a negotiated agreement?" I have found that it really helps focus my clients on their bottom line.

Listen.

Hank Dugie there are quite a few books available on negotiations. There are few different negotiation styles that you should know about - and act accordingly!

Overall, negotiations are for win-win! Always be ready to give up something to get something! Meeting half-the-way is another trick for a late stage in negotiation. Asking for more than what you really want is another trick - again in case of multiple offers, this may not work.

I'd say, negotiations is an art. Play smart  to win for your clients.

LISTEN. You can hear and sense what is on the table that might be movable and what are the real sticking points. Don't present a rigid position on anything. Discover the best win-win that's possible for all parties.

Hank,

Always have something in your pocket to give up.  A

Make them like you first.

Just say NOTHING!

I'll give you 3 negotiations tips,  Be Truthful, Honest, and of course, be friiendly.

This is very useful.  I like the win/win goal, and the preparing your clients to understand the value of giving and getting.  What is the ultimate goal?  Everyone satisfied with the outcome.

Cooperate with the other agent and work towards a win-win situation for both buyer and seller.

I got some tips from the answers here. 

It's a philosophical one, Hank -- I believe everyone has to walk away from the negotiating "table" feeling like a winner. If you keep this in mind and make it a win-win for all the parties, odds are you'll get it done.

Negotiation of what?

Know your facts, be confident, and just do your job the best you can.

The best negotiation tip in my book would be to be yourself.

In this market it can be tough, somtimes its just about getting the home.  know what motivates the seller. moving quick, information, strategy and the ability to change directions if necessary Will get you the home.  

I like Cindy's answer: BATNA...best alternative to a negotiated agreement. When I have a BATNA discusion with my clients, it helps them get clarity before going into the negotiation. As a result, they tend to get more/give up less, and stay cool-headed.

Stay calm, assertive and professional. 

I like Gabe's , Alexandra's and Annette's comments.  It depends on the situation and the client for me.

With whom am I negotiating? Are they sensitive to the power of NO!

What do I know they really want?

What did I pre-stage for them to need?

Not knowing more, the #1 resource is the communicated desire to make a deal with assurance we are all working for a suitable solution.

Moral to the story: Don't enter negotiations unprepared.
