If you are a non resident of Canada and are trying to purchase a residential property that requires mortgage financing, then you should likely speak with a mortgage broker about condo mortgages for non residents.
These mortgage programs are equity based with at least 25% down payments required along with a third party property appraisal that supports the value of the purchase.
The funds for down payment need to be validated before mortgage proceeds can be advanced and the signing of the mortgage documents must be done in person by the borrower and cannot be done via a power of attorney given to a lawyer or business representative.
