Can i just buy and Illinois tax certificate?

[Mike Chubb]

if a property is bought by a tax buyer and is about to be deeded can I buy the certificate from the tax buyer so I can own Said property at the tax bought cost?, Can those certificates even be transfered from one buyer to the next? Since I don't have any right to the property if I paid the taxes off I still wouldn't have claim to the property and couldn't fix and flip it correct? I'm under the assumption that I need to either get the certificate or have the owner/owners quit claim it to me before the property is deeded right???
