I wasn't in ATL during the peak, so I don't have a ton of empirical data, but I agree that the parts of ATL that I've been investing in (west surburbs) are down WAY more than 15%.I'm picking up REOs left and right at 20-30% of peak market prices, and even properties in very good condition appear to be down 30-40% the past year or two.

Where did you get the data from that 2006 was the boom?

Based on the last year or so of Case Shiller data, it appears Denver has leveled out.

Start calling homeowners with homes for sale (off market) and pull data (HOA fees, neighborhood info etc.)

In just the past month, I've met a handful of clients who match that exact demographic: young professionals who are ready to get their piece of the American Dream, but see how much a piece of crap 1950's tract-home is going to cost them in the Bay Area, and think to themselves "you've got to be kidding."

So we can then analyze the data, view the property, and make an offer.  

We are currently working in CA, GA, AL, PA, IA, and IL, and are willing to expand.We need agents who can provide us MLS one-line data for their markets in csv or xls format. 

@Heidi Wills so I would add a bit of perspective to the "winter low to summer high" data.

It's funny because whatever point of view you have, you'll find news and data to support that point of view.  

So, what data would you go by?
