It's working already, and it's sending a very strong signal—a message that the Opposition refuses to talk about because members of the National Party don't want anyone to know about it. One of the best things this bill actually does is encourage investors to build more and more new houses and new homes to rent. If you are planning to invest in housing for the rental market: build new. Build new and help contribute to the housing supply. Because the more we build the more affordable housing becomes for more people. Even if you are a mum or dad investor who has a rental property that you are renting out, and may well have had for more than a decade, here is an opportunity to take advantage of interest deductibility by building new and investing in new, and selling your old one. Be part of fixing the housing crisis by selling your existing rental and having a modern investment by investing in a new build for the rental market.
