Investing in Ottawa, Canada rentals... as a non-resident.

I’ve basically lived my whole life in Ottawa/Gatineau and then went off to live in a tax free country to hoard some savings. I’ve been registered as a non-resident for the past 5 years.

I’m estimating I’ll probably stay here for another 5 years before going back. But I’d like to come back with already a few doors under my belt, kickstarting a career switch “nest”.

Which kind of difficulty am I looking at to start with the first property from a distance, then to eventually have around 30 by the time I get back?

All I know is that a property manager is a must, but home inspection before purchasing and rehabbing with videos/images from a contractor I have no idea where to start.

25% withholding tax is a killer but an accountant could help apply for tax reduction, etc...

What kind of team would a first time investor from distance start with?
