How easy would it be to automate comparable market analysis?

[Antonio Lacava]

What is your opinion? Where would you look or how would you go about doing this? At the very least, we would need to know the differences in location, size, condition and amenities.

[Matt Lefebvre]

If a multi-billion dollar company like Zillow, Trulia, etc. can't accurately estimate the price of a property every time, I would say that its next to impossible to do.  Its impossible to aggregate every data point you would need to come up with a 100% accurate analysis each time.
