1.  Pricing based on what you need — not what the market will pay

2.  Skipping pre-listing prep and leaving money on the table

3.  Accepting "we'll put it on the MLS" as a real marketing plan

4.  Waiting for the perfect market instead of selling strategically

5.   Being too restrictive with showings and killing your own sale

6.  Treating every offer like an insult — and walking away from good money

7.  Choosing an agent based on the highest price, not the best plan
