I understand that currently capital gains are exempt on a principal residence in Canada. We are in a situation where we could purchase my FIL's property which is his principal residence but do not want to take a mortgage on the property to do so. We are considering having the terms of the sale be structure as a partial sum is paid now and the remainder in installments. We can afford to do so without taking loans. Any concerns in doing a sale in this way? In particular, would the future installments be considered taxable for my FIL? I have a few other questions, thoughts and concerns but have tried to keep it simpler for now but would be able to provide additional information if needed.
