Getting the Answer from the Maricopa County Assessor’s Office:
After being on hold for about twenty-five minutes with the Maricopa County Assessor’s office, I finally got the answer to my question about my own Limited Property Value: and guess what? I was wrong!
I should have dug a little bit deeper in my research, but I partly blame iMAPP, a third party provider to the Arizona Multiple Listing Service, for throwing me for a loop.
Using iMAPP’s Tax Report for my own parcel, I based my assumptions on the LPV they provided for my calculations about the assessed value of my own home. Granted that “the LPV cannot ever get smaller” was a hint in and of itself. However, I should have checked the horses mouth (the original data source).
Now I feel a little stupid, but that will pass. Making mistakes is an inevitable part of blogging and even though I try real hard to avoid mistakes, they happen. On the other hand, making mistakes also has some benefits. How else would I have found out that iMAPP is not perfect?

A Question of Value or a Question of Error: at the end of the day ends up being a user error aided by incorrect data provided by a third party provider.
Yes, maintaining the public trust is not only difficult when market conditions are changing, but it gets a little tougher when a data vendor throws in a little wrench.

An important factor to note about IMAPP is that they are required by ARMLS to use the same data vendor that originally was providing data to Net Value Central (previous ARMLS Tax provider), Whereas with almost every other state that IMAPP covers they normally are purchasing data Directly from the county and processing it themselves. The chance for more errors occurring increases as more “hands”, so to speak, are touching that data before it’s ever displayed. IMAPP will gladly fix anything that’s not displayed properly but the error has to be routed to the source of the problem first before it’s fixed on the IMAPP website! Hope this helps!!!!
