I do not know of any such sites; however, my clients, when talking to a potential seller, listened to their pain points and tried to understand and empathize with their core 'why?'

I am also going to talk to more of my family and friends to see if I could potentially work out a partnership.

Considering the local anti landlord laws what would be the best way to handle this to avoid any potential issues from the legal perspective?

Building equity and e­arning additional income are potential be­nefits.

More importantly was realizing that if I'm uncomfortable with the accessibility, then potential renters will be too.

I understand the potential value to convert but would like to use an outstanding calculator to actually show the value of different conversion options and investment percentages.  

Costs are up, but so are asset values and potential rent increases.

It's high risk potentially not so high reward situation. 

The realtor now can only work with half of their potential customers.

However, this comes with the caveat that you and your husband are prepared to cover any potential increases in mortgage payments after the renewal, especially if the new rate is significantly higher than the current 3.5%, which I ignore since I am not versed in the mortgage system in Canada (although it does sound a bit like an adjustable rate mortgage from what you described).Before making a decision, I recommend speaking with a financial advisor or a mortgage broker to explore your refinancing options and get a sense of what rates you might be looking at come June.
