You are  planning to retire to your modest cottage on lakeside.
Now you are buying a lakeside condo and hopes to travel for two
or three months every year.
If the value of your secondary residential property-such as a cottage or rental condo-
has appreciated more than the house you live in,
you can reduce your tax bill by declaring the cottage your princiapl residence when you sell.
Your home then becomes a secondary residence and subject to capital-gains when you sell it.
But if its value hasn't grown as much as your other property, you'll take a smaller tax hit.
