Need help finding sale price for comps before speaking to a broker to better arm myself with information. I need to keep my interest in selling on the DL because the local community is obsessed with my property and doesn't want any change.
I'm trying to find the sale price of a particular comp in LA county that sold a few years ago. Listing broker was not helpful. In order to request documents from the Los Angeles County Recorder/County Clerk Real Estate office I need to know:

1. The title of the document. ---Which document should I request Deed/mortgage? 
2. Property description-- Street address? Parcel number? Need the deed to know legal description. 
3. Last/business name- I don't know for sure what entity bought the property. I just know who developed it. 

Is this something any broker could find on Costar? 

Any suggestions would help. Thanks!
