A change in government at this year's election could prompt a drop in house prices, real estate experts say.
David Whitburn, the president of the Auckland Property Investors' Association, has been scrutinising political parties' policies and how they might affect the property market. He said if National were to remain in government, people could expect the status quo. But if they were in coalition, or if Labour pulled together a "grand coalition", there could be changes.
Whitburn said there was a lot of attention paid to Labour's capital gains tax plan but less on ringfencing, which would have a more extreme impact.
Ringfencing would mean people would no longer be able to offset a loss from their rental properties against their salary or business earnings. Whitburn estimated tens of thousands of investors in New Zealand who held negatively geared investment portfolios would be hugely affected.
He said when Australia implemented ringfencing in the 1980s, rents in some parts of Sydney increased 35 per cent.
