Hi again - If the property has a mortgage - that means the property is used as a collateral - and to transfer the title to your own name - the property must be refinanced.
You may not transfer the title to your name - and refinance after that - these two transactions must be made at the same time.
The first step should be to contact a mortgage broker and get pre-approval for refinancing.
Then - you will provide all documents about your income to that broker - and they issue the new mortgage into your name.
On closing date - that your mortgage will pay off the mortgage of your boyfriend - and he will be released from mortgage obligations.
Then - all documents will be sent to country for title transfer - the broker will be able to help you to prepare the Documentary Transfer Tax Affidavit which must be included.
That might take a couple of weeks - and the deed will be in your name.
As an alternative
- you may break the transaction in several separate steps - but that might take longer. As you suggested - your boyfriend may add you to the title - but because the property is used as a collateral for the mortgage - that is subject of approval of the mortgage holder. Normally - banks require refinancing for any title changes - in this case - in both names - so that might trigger additional cost.
So - I suggest to contact a mortgage broker and try to complete the transfer in one single step.
Let me know if you need any clarification this matter.
