For example,  providing a heating source for your tenant is your responsibility as the landlord. 

The unit shares the same heating and cooling as my own house.

The first house that I bought was 17 years old, 3 br, 1.5 bath, brick ranch house with hardwood floors, Andersen windows, ceramic tile baths, gas heat and a brand new roof. 

If the tenant complains there is no heat, you should respond.

[I think someone else provided an example of this case earlier]-Now provided you do qualify for purchasing a house (4 units or less), you will have no problem qualifying for a mortgage with a Schedule 1 bank as long as you provide the down payment (35% minimum of purchase price) and confirm proof of fund and the source of it- On the proof and source of funds, the banks would want to see an income enough to cover the mortgage payment and other expenses. and in some cases, they would want to make sure they know how you're going to cover your expenses (housing, heating, etc..) where you live.This is usually where it gets annoying for some folks but if you can satisfy this, you should be able to qualify for a mortgage just likely any Canadian tax resident, albeit you will pay a little more in terms of interest rate, etc.

i do not however use it for heat mine is an AC only unit I believe not a heat pump unit.If you're whole unit is relying on one mini split for ac and heat that surprises me just given if you shut a bedroom door you'd not have heat from the split that I assume is in the living room. 

New floors, appliances, heating/cooling, etc.

Especially in the winter in heated apartments if they can see a warm place to sleep they are going inside.

yeah the tenant pushing back is my concern. it just so happened that this happened with the tenant that seems to not like paying. and the heating is electric and this winter has been extremely cold which caused the electric bill to jump up to $800!

We ended up replacing the AC unit as well as the heating/gas furnace for 15k in total with TMS.
