@Claudia Diarte  Unfortunately because of the vast differences in how appraisers learned their stuff over the past few decades, one appraiser is going to use a completely different methodology than another.

@Kenneth Garrett thank you for your response, and it's very helpful to have concrete data points to give me some context! 

The most conservative assumption is to use purchase price as appraised value, but most other comps are lower without rhyme or reason for methodology.

Even if you use Z-wave, the devices will still transmit data over the internet.

Was 21% a few months ago.Oct closings down 46%, listings up 92% vs last Oct.As data catches up I expect YOY price increases to continue to fall.I am not a buyer at this time.

@George Gipson III, I think the various messages in this thread already have driven the point.

I just prefer to know exactly where my data is coming from so I can keep KPIs accordingly. 

It is driven by the market you are in.

That said, there are other places with lots of resources and data like a local REIA group, local forum posts here on BP, etc.
