My expectation early in 2021 was that with LVRs returning from February and set to be strengthened from May, investor tax rule changes announced late in March, new density rules announced late in 2020, rising house construction, and hopefully an end to the covid environment, that house prices would rise maybe 5% and a bit more.
Instead, they soared by 23% in 2021. This extra 18% jump in prices reflected a wide range of things including continuing strong FOMO, too much money being pumped into the economy by the Reserve Bank, greater than expected strength in the labour market, a strong jump in net migration inflows, and rising construction costs.
The extra jump in prices was assisted by the complete absence of any solid evidence of a wave of investor selling in response to the tax changes and legislation strengthening tenant rights. But from just before the middle of the year fixed mortgage interest rates began rising and by June this year were 3.0% - 3.2% higher than back then.
