I had property management once tell me they couldn't do anything because the tenant hadn't given notice yet and still had some property inside when they posted pay or quit, but the power company had told me the heat had been turned off when I called to check (apparently landlord utility revert doesn't work properly if tenant just doesn't pay). 

There are also alot of podcast these days with Canadian specific content you should check out the andrew hines podcast, rise podcast and Erwin Szeto.

I am not shy about it on BP and routinely point out the differences between Turnkey promotional companies earning referrals and Turnkey operating companies who earn on the goods and services they provide.What you described in your question is different than most turnkey promoters and different than rent to retirement. 

They also should have been doing regular checks on the home. 

One of my clients has an etrade with about 650K in securities - 350k LOC at 7.25% last I checked with him two weeks ago. 

Now, this seems like a model of retirement that’s worth spending more time on than spell check.

In my experience, income criteria, past rental & background checks works 90% of the time.
