August 15 - Cromford® Public has been enhanced to include a chart showing the percentage of home sales by intended use stated on the Affidavit of Value. This chart is based on recorded deeds in Maricopa and Pinal counties and allows you to track the percentage of sales to inventors or to iBuyers as well as primary residences and second homes. A few sales have unknown intended use because Affidavits of Values are not required for trustee deeds. If you have a subscription to Cromford® Public, please go here to request the new chart.

July 30 - The Agent Production table has been updated to July 28.

July 14 - Mike Orr is on vacation and off-the-grid from July 14 to July 23. Please contact Tina Tamboer if you need any assistance. Her number is 480-250-0587 and her email is

July 7 - We have added a tab to the Tableau chart showing List Price versus Sales Price. The new tab shows the median percentage of list price achieved by closed sales. Filters are available for Dwelling Type, Transaction Type, County, City and ZIP Code.

June 2 - Tina Tamboer has created a video analyzing the issues of affordability in 2018 versus the peak of 2006. You can download it here.

You can also download the accompanying slides as a Powerpoint file here.

March 26 - We have added 3 fix and flip analysis charts to Cromford Public

  • Monthly median acquisition and sale prices
  • Gross percentage gain map
  • Median value by city

March 25 - We have added a Tableau chart covering seller paid or assisted closing costs.

March 13 - We have added the year 2006 to the ZIP code charts showing the annual average price per square foot and the annual median sales price. This is intended to allow users to compare the current price levels with the peak during the bubble years. Although some ZIP codes peaked in 2007 and 2007, the majority peaked in 2006. The writing was on the wall long before the financial collapse of 2008.

February 10 - Mike Orr is taking a week of vacation between Feb 10 and Feb 17 to cruise the English canals with his family. He expects that internet connections via mobile phone will be a little spotty. Tina Tamboer, who just returned refreshed from a long weekend skiing, will be manning the fort and is recommended as your main contact on or 480-250-0587 for all things Cromford. Normal service will be resumed on February 17 when both of them will have a good internet service again.

January 30 - An Agent Production Table is now available for 2018 - year to date - you can find it here.

January 28 - An Agent Production Table is now available for 2017 - you can find it here.

January 20 - A comprehensive Powerpoint presentation - Year in Review - has been added to the Downloads section.

In addition a video using these charts is available in our Video section.

January 19 - More education is now available. One on one help is now available for a modest fee from Michael Murriett. Michael can advise you how to use Cromford Report content on social media and apply your own branding or watermarks. Please contact Michael for details at

January 5, 2018 - We are removing some of the charts focused on distressed sales since these are such a small percentage of the market these days. We will re-introduce them at a later date if distressed sales start to become an issue again. If this is a problem for any subscriber please let us know. However we thought that the time spent keeping them up-to-date can probably be better spent on creating new and more topical charts.

December 8 - We have uploaded our first video for subscribers. Tina Tamboer discusses the luxury market over $1 million using a variety of Cromford charts. You can watch it here.

December 5 - We have added 5 new charts to Cromford Public covering multi-family permit counts in Arizona since 2002.

October 29 - We have added a new Tableau chart showing List Price per Square Foot versus Sales Price per Square Foot.

October 14 - We have changed the Weekly Appreciation chart to use the annual average $/SF instead of the monthly average $/SF. This gives us a less volatile reading and allows us a much better interpretation of the underlying data.

August 19 - We have added charts about OfferPad sales and purchases to Cromford Public.

August 8 - We have received several requests from Cromford Report subscribers to see if they can subscribe to Cromford Public as well for a bundled price. We have decided to offer both together for an annual rate of $450, starting today. It is also possible for existing annual Cromford Report subscribers to add Cromford Public for the upgrade price of $150. Since Cromford Public subscriptions are annual only, we are not offering bundles for quarterly or monthly subscribers to the Cromford Report. However you are welcome to convert to an annual subscription and add Cromford Public at the same time.

August 3 - We have added a weekly active listings chart by city that excludes listings with UCB and CCBS (and the now-defunct AWC) status. You can find it here.

May 8 - We have updated our list of Canadian Owned Properties with the data from the 2018 tax year files from Maricopa County. We have also found a new way to integrate the Canadian Postal Codes with this file to make it more useful than the old version. This data comes from Maricopa County files maintained and supplied by the Information Market. It is not error-free, but reflects what the county has on file for sending tax bills. Therefore they are well-motivated to try to keep it as accurate as they can. You can purchase the list here.

May 5 - We have added a new Tableau chart - Dollar Volume. This shows quarterly dollar volume for closed listings within Greater Phoenix since 2001. It has the usual filters for county, city, ZIP code, dwelling types, transaction type

May 3 - We have added a new Tableau chart - List Price per Sq Ft for Active Listings. This plots the average $/SF from 2011 onwards on a weekly basis and has the usual wide range of filters for county, city, ZIP code, dwelling type, transaction type and price range. There is also a second tab that allows you to see the percentage change since last year. Thanks to Tina Tamboer for developing this chart.

Jan 1 - In a major development for 2017 we are introducing Cromford® Public - a subscription service that does not require membership of the Arizona Regional Multiple Listing Service. It relies entirely on data extracted from public records so anyone can sign up for this information, including ARMLS members. This in no way replaces the original Cromford® Report, but provides additional information that was not available before. There is data extracted from the county recorders in Maricopa and Pinal Counties, from the County Assessors, and from the US Census Bureau, Freddie Mac etc. Because of the nature of public records, the reports are not quite as timely as ARMLS data, but they are more complete since almost all sales are recorded. Cromford® Public includes information for Maricopa and Pinal Counties for:

    • Home sales (including non-MLS transactions)
    • New home closings (the majority of which are non-MLS transactions)
    • Average sales price per square foot
    • Average sales prices
    • Median sales prices
    • Home sizes
    • Interest rate history
    • New home permits (for all 15 counties within Arizona)

Please note that there is no information on housing supply, since that requires access to the ARMLS data. Hence our commentary on the market will still be confined to the usual sections within the Cromford® Report.

Most charts within Cromford® public have a filter which allows you to include or exclude 55+ communities, a function which has been desired for a long time. Other filters include transaction type, including MLS and non-MLS normal sales. It is possible to distinguish between pre-foreclosures and short sales with no active notice, and between bank owned and GSE-owned REOs.

We will be developing and adding to the charts in Cromford® Public over the next several months. We welcome requests from users.
