Off market deals. county lists

[Blake Dennis]

Was wondering if anyone has any experience talking to their county about getting specific lists of houses in a certain area they are investing in. If I were to find small multi-unit properties (2-4unit) that are owner absente? Is this something you can get from your local county assessor? I have heard of things like "list source" and whatnot, but was thinking there should be public information on these properties, because the tax information is public record. Am I missing something here? Thank you for your tome time
