I’m just trying to make sure this is perfectly normal!

Only one application passed, but that person chose a different house in the end.An agent that’s part of the brokerage I used to purchase this house stated he observed houses take 4-6 weeks to rent out but were in week 7 now.Is this timeline and # of applications “normal” for lower city Hamilton?

What I told myself is that I need 6 months of income plus some. 10k isn't a lot at all, if you live a normal life that'll probably get you 3 to 4 months living frugally and then what?

Is that normal practice, to charge sales tax for both labor and materials?

Normally, I would urge you to invest local for your first property.

But, yes you'll also have to be responsible if it breaks down through normal use.

Vacancy rates outside of large big box retail space are kinda normal. 

For normal rental investments I use 5-8% depending on the area...it can be even higher for a house hack since you're just renting out bedrooms and potentially shared bathrooms to people.

The leases the tenants sign have a clause stating the landlord reserves the right to make improvements on the property and the construction will be during normal business hours. 

Not much you can do if you do not get cooperation from the tenants in a normal situation never mind when they have local laws protecting them.
