Hi

Many auction houses do advances and they treat it like an advance and not a loan. They typically give up to 50% of their estimate of the item. A lot do advances on items as little as 10k that I am aware.
However if the auction house allows reserves they usually do not give an advance if you put a reserve since if it does not sell it could be an issues.
Also if you take an advance they usually either not give you points back if it is a card desirable to them that the want or my not give you as many points as they would since they are advancing you money
