Hi Berk..
You are absolutley right on the expenses and the rest of the costs,and it is like any other mortgage..you're in it til your sell and pay it off or you pay it out...But in my case it was a long term planned investment and I was getting compound interest and adding to my wifes RRSP as well as my own at a much higher rate of return than a standard mortgage...and I was paying myself..
It worked well when my wife wasn't working therefore no income to build RRSP contributions on..the mortage payment went in every month and that cash I used to build my stock portfolio..inside our spousal SDRRSP's..
Like I originally said ..I lost most people who couldn't fathom the concept,but you seem to understand quite well the concept..
It worked for us..
I'm happy...retired...and have $x,xxx,xxx.00 portfolio...so it must work..
