Hey @Allende Hernandez - nice work with cross-checking the tax delinquent status.
I've heard this issue come up with a few other people over the past few months (specifically regarding the tax delinquent status not actually being up to date in their system, even though the data was pulled from a fairly recent date), but that's the first I've heard of the actual ownership being that far off... that is a little concerning.
I think the accuracy of some counties is somewhat dependent on the county itself (because some counties are very good at providing current data, others are pretty bad). If you've found that the information is this far off in that particular county, I think you can safely conclude that you should find another source of data from that county for your direct mail campaign.
I don't use AgentPro247 for my delinquent tax lists anymore... and it's for this exact reason. Even though their lists can work well for certain types of direct mail efforts (depending on what types of properties and owners you're targeting), they're not always the best fit for everything, and some counties (usually the more rural, sparsely populated ones) have issues like the ones you're seeing.
If current tax delinquent data is part of what you're relying on, I'd say your better option would be to go directly to the county and get it (because the county is always going to have the most current and accurate information on hand).
If you're looking for some other services that provide lists in a similar fashion (though, most of them don't even give the option of tax delinquent data), you can always check out this review I did on 5 of the more well-known services to choose from. You might find it helpful.
