1. Cares more about your priorities and your money than their commission. As your fiduciary representative, that is actually an agent's legal obligation. (And in a business based on reputation and referrals, it's also smart business.)

2. Negotiates effectively and, at your instruction, aggressively to achieve the best possible price and terms. (A good agent who knows how to negotiate can easily make a 5% difference in sales price when compared to a mediocre one).

3. Never makes decisions for you nor pushes you to make decisions a certain way, but lays out all the information, options and strategies for your consideration.

4. Ensures you understand what's happening, what's necessary and what's at stake at every step.

5. Tells you the truth as best as can be discerned: positives, negatives, upsides, downsides, changes in the situation, even what you might not want to hear.

6. Offers an array of qualified professional resources -- inspectors, lawyers, escrow and loan agents, etc. -- and advises you when their counsel is required.

7. Coordinates, manages and controls -- based upon your decisions -- every aspect of the process. Always with an eye to protecting your interests.

8. Knows the market in your geographic area and property type inside out: its values, market trends, neighborhoods, pros and cons, legal issues, its agents.

9. Gives you the time and attention you need.

10. Keeps his or her promises. Works hard. Works on your timeline.

11. Has excellent client references.

12. Ideally, loves the business of real estate -- because it's simply more enjoyable to work with someone who enjoys what they do.
