Hello, myself and my wife bought an apartment in 2005. Then in 2010 we needed more space because we started a family. We were lucky enough to get a mortgage and the bank allowed us to keep the apartment. We then bought a house and rented out the apartment. My question is will the fact that the apartment was not our PPR for a number of years have any bearing on the tax situation? In turn, if we sold the apartment now (after 10 years of paying down mort) for less than we paid for it would we have any tax liability on the difference bewteen the mortgage value and the selling price, seeing as we would be receiving less than the purchase price? I ask because I am hoping to avoid any nasty surprises when we sell the apartment. Thanks in advance.
