It is but adding supply has a built in delay as things need to get zoned, infrastructure added (ie - roads, water, fire and police...), and then things need to get built - a multi-year solution.
Exactly. The system was in more or less a natural flow - families moved out of condos and into SFR and others in SFR moved into condos in a reasonable rate difference (ie. sometimes more one way and sometimes more the other). It's the high rate of investment flows is what knocked everything off the normal situation as any market will have some investment flows (ie. 'normal' landlords who buys extra properties and rents them out). So, the 'easiest' and probably safest and quickest way to get back into a normal flow is to focus on the high rate of investment.
