I highly recommend you NOT list your house with Dave Vallee. We always think it's best to go with the big guy in the market, but take it from my experience it's the wrong choice! The big guys (Dave Vallee) do not care to fight to negotiate the best deal for you.
In my circumstance during mid-negotiation, Dave threatened to not accept my opinion to make a counter offer. He said, that if we made the counter offer, he would take his name off the listing. Stating that if I did the client would back out and therefore he could not be of service to me. I disagreed and luckily I had two realtors on the listing, and was able to put the counter in with the other one. That said, I did counter and we did get more for our house, because WE pushed!
When in the moment of pure stress, you do not need your realtor to add more pressure. Then threaten to quit, and then on top of that expect to still get paid for his services? I don't know another industry where if you quit in the middle of job, you still expect to get paid!
In my opinion, Dave is used to listing houses and getting multiple offers, and doing very little negotiation. My big concern, is if he is threatening me an educated male in his mid-30's to remove his name from the listing, what is he saying to the 80 year old person whose spouse just pasted???
Find yourself a realtor who will fight for you, to get as much money as possible for the biggest investment in your life. Find a realtor who is hungry for your business and willing to negotiate the best deal possible!!
Don't let the first words out of a Realtors mouth,"I know the market, I have been doing this for (X # years)" sway you. NO ONE truly knows what is going to happen in a market, if they did they wouldn't still be working.
