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 4 - Mike Orr now has a Skype number with a Phoenix area code, so you call call him based on local rates - it is 623-399-4889. He will receive this call as long as he is connected to the internet anywhere in the world. We still recommend email as a more reliable contact method in most circumstances.

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.

July 28 - Mike Orr has escaped the clutches of Verizon Wireless and is now in the clutches of BT in the UK. The old phone number 480-262-5839 is out of service and replaced by his UK mobile 011-44-7484-223929 which can receive calls or text messages. This is normally in a time zone that is 8 hours ahead of Arizona. Anyone wanting to reach a local Phoenix Cromford person is advised to call or text Tina Tamboer on 480-250-0587. You can also contact Mike via Skype where his ID is mike.orr5. Email is probably the most reliable and fastest way of getting a response from either of us - see the Contact page for details.

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.

Apr 9 - Introduction classes for the Cromford® Report are run roughly once every 2 months by Asel Nelson at the Arizona School of Real Estate and Business. The next one will be on April 12, 2017 1 p.m. at the Gilbert campus, followed by May 10, 2017 at 1 p.m. at Scottsdale campus. For registration please use this link:

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.
