Fire him right away !!
My first agent was like that when we bought our first house. Till this day
I regretted a lot that I didn't fire her in the beginning because of "不好意
思". She wouldn't give us any suggestions regarding the house and the
offer price, always says something like "it is your own decision,
blahblahblah..." Thus our first house purchase was a really bad
experience, we ended up buying a way over-priced house.
My current agent is very helpful and gives us lots of suggestions. I can
feel a huge difference.
Not all agents are bad, go find a good one. Good luck!
