Purchasing my 3rd property

[Ashar Syed]

Hello,

This question is for my fellow Canadians; I currently own two properties, and I am/have already purchased a new construction condo.  I have made the 20% payment to the developer and my closing is Sept 2020.  Should I prepare to put down an extra 10% to secure a mortgage upon closing or will the 20% down payment pretty much guarantee me a mortgage?  Which bank should I approach?  

Thanks,

Ashar
