• Will interest rates  plummet? At the start of 2008 two-year fixed home lending rates sat near 10 per cent. They fell to 6.5 per cent in 2009, then 5.5 per cent in 2012 and now sit  below 4.3 per cent. 
• Will they fall to 3.5 per cent or 2.5 per cent? In the next few months falls to below 4 per cent are  possible given the slowdown in the Australian economy, which will  impact  inflation and interest rates here as they eventually cut interest rates further in 2019. But the big structural falls in interest rates, which have transferred into structural shifts in house prices,  have happened. For your guide, a just-released paper by the Reserve Bank of Australia concludes that every 1 per cent  cut in interest rates over there boosts average Aussie house prices by 17 per cent.
• Will net migration again rapidly turn from a net annual flow of -10,000 to a gain of a net 64,000 as happened between 2012 and 2016? That is  unlikely. The latest flow sits just below 50,000 and is slowly falling. A fresh surge seems very unlikely, not least because a surge seems usually to reflect a  shift in the trans-Tasman flow, and that flow is no longer headed for big negative territory — last seen as -40,000 in 2012. Lack of data due to the removal of departure cards at airports mean we will never again know what the Tasman flow actually is.
• Will we again start from a position of house construction being the worst since the 1960s, as happened in 2011? Maybe  this will happen again, associated with another global crisis — in which case house prices will probably plummet for a while. But in the next few years such a scenario seems extremely unlikely with all efforts being made to address house shortages in our major cities — shortages which will probably persist for years if not worsen in Auckland and Wellington.
• Will we again see the big loosening of lending rules that happened in the 1980s? No. The world is moving to more restrictions on bank lending. Rule loosening was not really a factor these past 10  years and instead we have seen the creation of loan to value ratios (LVRs) and eventually the Reserve Bank will impose debt to income rules (DTIs).
• Will we again see a large fall in the unemployment rate, such as happened from 6.7 per cent to 4 per cent between 2012 and 2018? Definitely once the next major downturn has been and gone. But not in the next few years with a wide range of factors underpinning NZ growth.
• And will we again see  new investors appear — foreigners and baby-boomers preparing for retirement and adjusting to low interest rates by investing in property? No. Foreigners are now substantially shut out, baby boomers will become net property sellers soon.
Given  already low interest rates, a world trend to tighter lending rules, low unemployment, high net immigration, and above average levels of house construction, it would be  unreasonable to expect the next housing cycle will produce the gains seen in this most recent one.
That  means the dissuasive effects of a capital gains tax or extended bright line  test on property investment may be far smaller than proponents hope.
Investors are probably  adjusting to a housing  model built more around good rental yields than  capital gain. That means higher rents.
