Good luck at the auction, make sure you have all the inspections done that you want done up front, as unlike a purchase an auction sale is final and if you then find any issues you can't back out of it.
I also recommend making sure you have some money left over to make changes/updates prior to moving in, maybe a new lick of paint or carpet or something along those lines.
Make sure you stick to your limit at the auction too, the last thing you want is to be struggling to pay off your mortgage in a couple years because you got too excited.
remember it's just like eBay only on a bigger scale, if you don't get this one, there will be another one you like on the market next week, especially now that we're moving into spring.
I wish you all the best with it.
