Have you spoken to your accountant about the capital gains event that is going to occur when you do this?

For everyones sake:

Please consult with your accountant before signing any contracts and be very skeptical about what the real estate agents' say to you.

I've had to deal with quite a few interesting situations due to clients taking the word of agents and not consulting with me first, a real estate agent writting something down on a piece of paper or the back of their business card 'does not', constitute advice 'and they know this', as they are not deemed to be a professional when it comes to the tax/cashflow implications of property transactions.
