The other consideration is that we will submit the house, including the addition, on the as-built drawings. 

@Robert Hernandez Well with this time of year there’s many things to take into consideration.

Would the lender take the 3 units potential rental income into consideration when deciding how large of a loan I can qualify for?

@David MillerI think that perhaps the answer to your question would be determined after a long conversation that takes into consideration everyone's facts, circumstances and goals (read: there's no simple, direct, easy answer here)."

The system should take into consideration the Service (From Utility to Panel), the Branch circuits (individual circuits running through the walls) and the utilization devices (switches, Receptacles, and other devices).  

My only thought at this time is continue to try and persuade him to sign it or start raising the rent considerably. 

My challenge is figuring out how the real estate landscape is different in Canada than the US, and what major differences do I need to take into consideration when exploring topics such as BRRRR investing and using leverage to purchase property.

I think if you consider it for awhile it becomes obvious that a multitude of considerations come into play that make a property a good deal.One illustration, I happen to know an investor in Seattle that is and has been doing quite well for years buying apartments, holding them for 5 years or less and selling them.

And then there are special assessments, etc. to be taken into consideration.

Then the number of units you would need grows considerably.
