Mortgage interest not deductible here (Canada). Our current mortgage rate is 3.8% so given marginal taxe rate of 46% I would need to have a guaranteed return of at least 8.3% just to match wha I would save by "investing" in my mortgage. You tell me where I can get a 8.3% return over the next 5 yrs, guaranteed. PS here in Canada (maybe exception is Vancouver) our housing market is v stable, in my City house prices did not even dip during 2008 crisis. Yay Canada!
