Hi Ed,
How are you? I'm doing a pre-construction syndication for investors @BISHA or BISHA.com check them out. I can provide investor package if you like. For more info info@cjrealestateinvestments.com
Now for your questions.
1. Tax is included in the purchase of condos, that is the price listed by realtors or developers.
2. As the end user you will be charged a land transfer tax, if you are in Toronto, that is now doubled! On a 500k condo lets say you are going to be looking about 10-15k closing costs.
3. You can do an assignment on the condo, if you are looking to flip it, that means that you don't atcually close on the condo, come time when the development is done. This is great if you are flipping, because you don't do step 2, the end user does step 2.
4. HST Rebate, this is only for first time home buyers, looking to purchase their principle residence. If you have a principle residence, this doesn't apply to you. If you plan to invest and flip, this also doesn't apply to you.
Hope that Helps
