Tell them what you think is accurate so you get the most accurate quote for a rate and cost.I also think the advice from Tim is a bit over the top so no wonder it's confrontational. 

When I am in the city, I am confronted by all the latest fads, cars, fashions, eateries, etc.  

Some folks get angry when I (we) confront ideas with some facts that will affect their plans negatively. 

I mean, you're super confrontational with replies, but my two cents is a good realtor will get you the deal and save you money. in my market those AVMs you say are "accurate" have about 8000 data points across the state.

And back to that phrase silence is golden,for the past weeks I have been confronted with a few circumstances that I know I can't share with too many people.

I’m not going to get into whether you should or shouldn’t try to hard-sell people in this e-book, only that there’s an easy-to-confront way of promoting yourself without having to ask others to give you anything.

Most people are non confrontational and will find it much harder to say no in person.

I feel terrible thinking how I need to confront my friend about his decision; however, I need to get him on this forum.

I'm sure it'll be a lot more difficult cold calling than direct mailing because of people's emotions and having to confront them directly.
