Looking for the average commercial rental rates per zip code.
Hey guys, working on a development project, and via API we'd like to run the average rental rates for each zip code (or city) in the US. Understanding this comes at a cost, so any buying recommendations are greatly appreciated. I can't use CoStar's info as it violates their terms of service. Data doesn't have to be fresh, just relatively accurate between zip code / cities.

I've used the webscaper app for chrome on a similar project with residential listings. I know this is not the answer you're looking for, but could be a free option that is a little work intensive.

Most asking rates are TBD, so yeah. \n\nYou can scrape market report information from brokerage companies, they post that on their websites. That would at least get you cities or as close as you can get with data. \n\nREIS does something similar, they take everyones market reports and then resell it. \n\nSeems like a huge waste of time, but sure, good luck.\n\nThere is also compstack, but getting that data regularly would be a huge challenge.
