What can I ask a broker? 

This video tells you what any real estate professional would tell you. Ask them:

• How long do homes in my neighborhood currently stay on the market?
• How would you price my home?
• What data did you use to arrive at that price?
• How would you market my home?
• What activities would you expect of me to market my home?
• How will you handle representation if one of your buyers is interested in my home?
• May I speak with sellers youve recently represented?
• How long a period would you want on a listing agreement for my house?

It is best to ask these questions, and be comfortable with your choices before signing a listing agreement.
