A newly built home in Sydney’s inner west sold under the hammer for $6.463 million – more than half-a-million dollars above its $5.9 million reserve – as tight supply continues to offset buyer angst caused by dwindling hopes of an interest rate cut this year.

The Strathfield sale helped push the preliminary clearance rate to 72.9 per cent across 2232 auctions in the strongest national result since the first week of May, according to CoreLogic.
