The realtor we use has a service that provides us with listings that match what we're looking for. I think that realtors have access to more details than the general public can..Most of my experience's with realtors has not been stellar. Constantly showing me houses that did not match my must have list. However when I was looking for my first bungalow I did have a great realtor, and he told me I would have to be patient as there simply wasn't many houses with oversized garages and the other must haves in my desired neighbourhood. So I was patient, and after quite a while he called me with a perfect match. He did not waste my time showing me houses that dud not match, I appreciated that.
When we see something that we like we call her and talk about it before we ever bother looking at it.
All that said, the market has softened here and we're not planning to move anytime soon.
