Just like any form of investment, diversifying is important. If someone is 100% invested in Loblaws stock, do you expect the government to defend Loblaws to protect their investment just because they’re relying on that to retire? The people made the choice to depend on a single volatile investment to retire, it means they took a chance that its value could drop.
Hell, it could happen for a bunch of other reasons, one bad neighbor fucking up their lot and your home loses value.
New homes means newly built, right? So if a model sells for 300k the company building it can’t just increase the price to 315k to compensate as it would mean losing the non-first-time home buyers who are willing to pay 300k as customers.
