Capital Gain Tax

Hi All,

I have a question hope some of you could shine some light on this one.

Please allow to go straight to a scenario example.

Bought first house, as a primary residential for $100,000.
First year, lived there, in the second year, rent it out. Now live with parents (pay the rent too)
Declared rental loss including raw materials.
If I decide to continue renting it out for another 3 years. And move back there and live there again in the future.
Later, after seven years, property worth $200,000 and if i decide to sell the houset hen, do I still have to pay captial gain tax because there were 3 years worth rental?

Any help would be good,

Thanks in advance.
