I've used Zillow & Trulia, both buying & selling, to get a very rough estimate...ONLY.

What I do look for though, are homes in the general area that have actually been sold recently (sales prices are often posted on other homes nearby) and then try to compare the SF price, amenities, upgrades, Etc., Etc....to the house I'm interested in.

I think this sums it up for me exactly....
