Auckland landlord Gary Lin, with 14 residential properties worth about $10 million, had planned to hold places longer and use expected valuation rises to offset capital gains tax.
"I've already got a strategy because we can't control what the Government does," said Lin of what he expects to be a punitive regime for landlords and who originally bought to play World of Warcraft on his computer all day.
He spoke in advance of Prime Minister Jacinda Ardern rejecting CGT. Lin had pondered a grim scenario of CGT coming in.
"On average, Auckland house prices double every seven to nine years," said the professional property coach and investor.
"If the Government taxes me 33 per cent on [investment property] valuation increases when I sell, then I will wait an extra three years because then the tax will be cancelled out by further gains," predicted Lin who has now sworn off games for real estate.
