Purpose : To prepare for my Art auction next week.
If you were to ignore the fact that the collateral you are offering is almost certainly not worth the amount of your loan, the reason for your loan makes absolutely zero sense. You are going to repay your loan prior to next week so you might as well use the funds that you were planning on using to repay for your loan to "prepare for your Art auction"
Also, I cannot think of any expenses associated with auctioning any kind of property (including art) that cannot be paid for out of the proceeds of the auction
