Ruffling a Few Feathers

Apparently I have ruffled a few feathers over on Trulia when I asked if their heatmap data was based on RMLS (inflated) figures, or on assessor data (more accurate IMO).

The thread is here if you'd care to join in.

Frankly I'm tired of having to keep portlandmaps.com up whenever I see a house listing, to get the true picture of the size of the house. I heard from a Realtor that RMLS requires Realtors to input the total size of a house (including unfinished basements and attics) not just livable space.

I realize that the assessor data can be wrong, but I feel that it's more accurate than the size data that RMLS posts. I'd like to see them change this policy, what do you think?
