Attending Tax sale... Advice?

[Ken Latchers]

Hi folks

I am planning to attend a County tax sale next month. 

I have never done this before. Assuming I do all the registrations and biddings right, 

It is a few thousand tax, plus all the listed transfer costs etc. And of course I have to win it if anyone else bids and pay with verified funds.

I know there is an existing mortgage, and I'm going to see if any other liens which I'm going to check with the county Monday for estimated amounts.

is there anything, like out of the blue, that I should be thinking or considering about?

the place is vacant but fully furnished and also on the market, so I guess I'm kind of clueless about what actually happens once it's mine.

like, is all the furnishings and appliances Etc become mine? Can I change the locks and make them deal with any remaining complexities?
