I just noticed on Larrys blog that April 9th marks the beginning of a new rule for CMHC insured mortgages going to self employed people. I hadn't seen this change in the list of new rules yet, so it's new to me, but this could be another one to have a fair amount of impact on the Vancouver market.
The new rule states that if you have no proof of income you can no longer buy with 5% down - you now require 10% down, and if you've been self-employed for more than 3 years you have to provide proof of income.
If you're just starting a new grow-op though, you can simply state your income and put down 10% for your CMHC insured mortage.
