Foreclosures in North Carolina

[N/A N/A]

I'm going to be visiting my county courthouse this week to watch the preceedings of several foreclosed properties. I had planned to just watch and ask questions but a few of the properties look like that have a good amount of equity in them.

Below is a copy of the legal notice. I'm not sure if I understand the wording 100% and have some questions about it and how it relates to the foreclosure process here in North Carolina ...

In addition to the winning bid purchase price I would be responsible for the excise tax and court cost. For example if the winning bid was $100,000 I would end up paying $450 in tax and court costs?
Since no personal checks are allowed does this mean I have to bring cash to the auction? Are the funds paid to the attorney handling the auction or they paid to clerk of courts or something? Is it normal practice to get a cashiers check for 5k or so as was indicated in another thread and sign it over if I have the winning bid?
I'm guessing I have 10 business days to pay off the remaining balance.
Since I can't gain access to property prior to the auction I'm purchasing it pretty much unseen since I can only view it from a distance from the exterior. Also any effects or personal property left at the described lot will now transfer to the winning bidder? Does this include cars that are left in the driveway or backyard?
I did look up the properties and to the best of my knowledge it is the first mortgage that is being foreclosed on (VA Loans for two of them). There aren't any deliquent property taxes on the properties so that is a plus. I'm not sure what other kind of liens I would have to be concerned with if it is indeed the first mortgage that is being foreclosed since it wipes out junior liens (2nds, mechanics, etc). Or am I missing something?

One last bit is about the current resident. In 3 out of the 4 properties that are coming up for auction there are people still living in the properties. What happens to them after the auction, redemption period passes and they don't file bankruptcy or bring their loan current? If they are still in the house when the deed effectively transfers to me I guess I could give them a friendly notice to move themselves and their possessions quickly. I would think approaching them negatively could only incite them and in some cases cause them to vandalize the place before leaving. I dunno maybe worst case thoughts there.

Woah, got a little off track there. Anyhow if you are in North Carolina and have had any experience with these foreclosure auctions any help would be greatly appreciated. Thanks.
