You can make the transfer without a tax implication if you can show you were holding the property in trust for your corporation all along. But watch out when it is time to renew - your lender may want company financials and a personal guarantee, and, as Mike says above, they may at time of the transfer want a personal guarantee.
So why not just do up Trust Agreements for all your properties, defining that you are holding the properties in trust for your company. You may need to demonstrate that you bought them with this intent, in advance of incorporating the company. Talk to your Tax Accountant about this no cost no hassle method.
I have a sample Trust Agreement I could email you if you need one, or maybe I could post it here somewhere. Email me at my address below if you want it.
