Pittsburgh PA Data? Where do you find accurate Lists?

[Lauren Hardy]

Hi Everyone! We were looking to pull some marketing lists in PA but we noticed the normal data sources like Listsource and Propstream are pulling incorrect data. We were trying to pull the last 6 months of market sales that were absentee owned to see the top zip codes, but data seems off. We were pulling comps, and it seems to be missing sales that happened. Is there something in PA that's stopping us from getting data there? How are investors pulling data?
