You reminded me of when I moved to Orange county, California in 1986 (ooh, I'm old!)- there were no houses for sale, per se- there were only houses which were sold.
Nonetheless, there is no real precedent for routine auction sales of homes in the US. But, when we finally found a house in CA to buy (it had been on the market for, no kidding, 45 minutes), we got it under contract within 2 hours, at $2k under asking price, and by the end of the day, there were two offer sheets to the sellers with offers substantially in excess of the asking price. Kudos to the sellers, who did not waver in their commitment to honoring the deal they'd made with us. A good deal, in the end, as when we sold the house almost four years later, the profit paid for law school.
Now (wacky market) all the houses which sell in my area of Dallas (good, solid houses, 3,000- 4,000 sqft [about 330-450 sq.m]), get torn down so massive houses can be put up in their place. Nuts.
Let us know how the auction turns out. And again, do you set a reserve price?
