Most Auckland properties sold within two years of purchase are "do-ups" being renovated by young couples working their way up the property ladder rather than investors, a mortgage broker says.
Prime Minister John Key said yesterday nearly one in five Auckland homes - 17 to 18 per cent - are sold within two years of being bought, data provided by officials shows.
But it is not known how many of those are investment properties that would be subject to a new "bright-line" tax on capital gain.
On Sunday Mr Key unveiled the new tax which aims to crack down on speculators who are turning a quick buck on the back of rising house prices. It will apply from October 1 to any property sold within two years of purchase that is not the owner's primary home. The tax will apply to domestic and foreign sellers, irrespective of whether they intended to buy the property to make a profit.
