I've never had good luck with any of those online foreclosure lists. Just cuz some of them can still have tenants or be shown actively to potential buyers. And it seems like all the lists I've seen were very incomplete.
What are you looking for with tax records usually? Delinquent payments, that sort of thing?im assuming youre looking for potentially squattable properties not to buy a foreclosure:
look for tax records in your county. depending on where you are, it might be online. otherwise youd have to go to town hall or the county clerk. either way its public information.
