Court House Auction Question

[Jordan L.]

How do I know if a deal if is a good for a online court auction. I am looking at some potential properties for South Florida. I know sometimes if you are not careful you can pay for something that is not first in line to foreclose. I know HOA Associatioans, Mortgage company Lender can become in line. I know IRS can be first and then Property taxes. How can I do my research on this particular property and how all this work.
