Additionally, I’m curious about how this would apply to properties in provinces like British Columbia, Alberta, or Ontario.

Coffered ceilings, low corner additions etc.Anyone can slap lipstick on a pig, looking for high value add in high demand markets is where the $ is.

Whether the seller was open to a buyer commission or not, I wouldn't put an additional cost into any personal purchase.  

Give them a 60-day notice, then charge them a prorated rent for the additional 20-day extension.

Many lenders also impose additional requirements such as owner-occupancy, and/or that one lender make all of the institutional loans in the building.- Valuation: The variety of financing products available as individual tenant in common loans remains limited, and the terms are generally less favorable than either apartment building loans or condominium loans.

I should have ran the plumbing for it even if I didn't plan to add it.  

This is an additional step that would not be present for developing a lot where you are adding value.  

I also make sure to specify in the lease agreement that I need proof of coverage before move-in and that the policy should name me as an “additional interested party.”

That leaves an additional market demand of 780 units.

Part of that is adding additional cost for increase in building products.
