DISCOUNT BUYING opportunities are coming to the fore in the commercial property market as a flood of small shopping centres, factories, office blocks, hotels, B&Bs and spas hit auction floors. Industry players say last year it was mostly residential real estate owners who were scrambling to offload properties they could no longer afford. A second wave of distressed selling is now under way, but this time around it's commercial property investors and small business operators who are cashing in their assets.
