Found your thread researching the same passage in J's book. I'm a newb but I do have access to MLS. It took me a minute but I am able to demonstrate a clear variance between sale price of listings with distressed signals attached to them vs. listing without distressed signals.
I checked out Realtor.com and Zillow to see how I might do the same on their sites. I suggest you make this a search for your real estate agent. Its really not difficult once you know what to ask/look for. Its a standard median sales price report with a few tweaks.
First I set base criteria (residential detached, # of bed/bath, city, county)
Then in a field called "Special Circumstances" that has some recurring keywords listed as options, I select the keywords that suggest a distressed property. (corporate owned/fixer upper/foreclosure/gov't owned/HUD Listing/No Disclosures/Potential Short Sale/Short Sale Pre-approved/Sold AS-IS)
The report returns median sale price, by month over last year for all sold listings that match my base criteria and were flagged with one or more of those keywords in the Special Circumstances field.
Then run the same report, but this time I select the "NOT" flag in the Special Circumstances field, which returns data only from listings that have NONE of those previous keywords.
Then run it a third time with the Special Circumstances field removed all together. This report returns median sales price for all listing regardless of circumstances.
Chop the data up in Excel and it comes out like this.
Should take an agent, or an agents assistant 10-15 minutes to get this setup, and if they save it for future use, even less time. I'll be running the same reports across a number of target cities.
