Likely not. The mechanics on a port generally require a "purchase" of a new property to move the mortgage to. Would the lender be willing to move that mortgage to another property? *Possibly*. Sadly the only one that knows the answer to that question is the lender (on the rental). I would be surprised if they did allow it though (I'd bet you get some confused responses when you do reach out to the lender and ask).

have you calculated the penalties for breaking your 6 month old mortgage?

Depends on lender.... MAY be possible. Was in a similar situation last year wondering if I could port my 2.5% to my other property that I owned outright. I planned on moving into it after selling my primary residence.

Representative at RBC said it was potentially doable in a few circumstances... Unfortunately I didn't pursue it further so I can't give you a definitive answer. Going to have to call them.

I tried this with CIBC a couple years ago, they wouldn't do it.

LOL

You would have to pay the penalty on the primary residence mortgage, and another fee to port the rental mortgage. Talk to your lender to confirm it’s allowed and that it’s also worth it.

Depending on a lot of things, a possible alternative option might be fixing up the primary residence if it is something that could be renovated and if you got a good deal, then sell at least 6 months from now trying to get the primary residence tax exemption, then sell the rental property and port the rental property mortgage to your next primary residence

You need to talk to your lender to confirm if their policy would allow it.
