Who's data do you trust more Zillow or Trulia

[Gene Hacker]

I know Trulia is owned by Zillow but I find it interesting how the sales data they post are different from each other.

Examples:

Bakersfield CA Median home sale price change year over year:

Trulia: -2%

Zillow: +6%

Bakersfield CA Average price per foot:

Trulia: $136

Zillow: $141

Has anyone found something similar in their area?  Any insight into which of these two options to trust more?

That's interesting since Zillow bought Trulia in 2015.

However, Trulia claims 65m unlisted home estimates and Zillow claims 110m.

Both algorithms are supposedly based on physical characteristics, location, and recent sales.

Zillow also correlates its Zestimate forecasts in with the ZHVI forecast for the ZIP / County / State.

My best guess is that Zillow's numbers are more swayed by the general area and Trulia's are more based on the property itself.
