Public Information & Comps

Hello,
I have a question in regards to the following:

1. How come some listings show the entire pricing history where others do not?
2. How does Zillow determine comps?

I am asking these questions because there are 2 listings in the same building complex (different addresses) that are almost identical listings, but the zestimates are vastly different & the original purchase price of one of them is not showing & the other is. The 2 units I am comparing are: 301 Main St. #20F & 338 Spear St. #21F. 20F does not show the original sales price & 21F does. Also, the zestimate for 20F is higher even though the units are nearly identical. Why would the comps be different for each? Is there any way to make adjustments?

Thank-you

You can get an estimate of the previous sale price based on the property tax assessment value. I pulled the records and 301 Main #20F seems to have sold somewhere between $1.20M - $1.24M. 

Keep in mind that similar units are usually valued higher if they are on higher flooers. Also these 2 buildings are not exactly similar when in comes to views.

Looks like that building is pretty messy regarding accuracy on property history. If a home does not have any tax history, it likely means it was a user created property and not tied to public records. That building has lots of units. It appears the units labeled with a a "T" are the ones from public record.
