I've used it, you can opt out and it's not the most reliable info.

In most cases their nimbers are so inaccurate that advice would never be reliable. 

The smaller guys just don't seem reliable and I am worried about my personal info getting into the wrong hands.

Hi,Any recommendations of reliable property managers for Chicago Southside rentals?

Is your major problem just having crews show up reliably?

Best part is, unlike listing data, rents are typically not negotiated downward and owners tend to have a decent grasp of their market so, the values tend to be about as reliable as it gets.

Is that a decently reliable formula?

Having used a lot of platforms, Go Daddy has thus far been the most simple and reliable source. 

Contractors who were once reliable, started cutting corners and doing crap work.  

Not being on the ground really makes getting reliable information difficult.
