@Inna Los here is an example from my county http://www.lake.iviewauditor.com/It is an online database of all houses in the county with details, tax bills, etc.

Get on the DC Real Property Tax Database, type in the address and hit search.

For instance, I own the two most prominent office buildings in a local tertiary market and those properties are not anywhere in the CoStar database, not even showing just minimal info.I do have a CoStar subscription, though have found that our personal market research for multi-family through online sites (Apartments.com, etc.), Craigslist, and local brokerage listings are much more informative, complete, and can be honed much more specifically to align with any particular property you are looking for.

I will say Attom has upped its game in the last few years concerning ML and AI.... so who knows, they might actually have cleaner data now, and overall it might be cheaper to buy from them as a reseller.First American are quality people, and they are scrappy... they have a huuuge database of scanned doc images that they have run ML against for the juicy tidbits of data a county/city does not collect or load onto public-facing .gov sites.Most of the data you are looking for, like accurate monthly parcel/assessor/people ect data can be had just by googling your county name with 'open data GIS' in the search string.

This clarity and focus enabled me to successfully analyze options and make educated judgments.One critical lesson I learned early on was not to wait until I felt completely prepared.
