There was a huge hiccup with the combination for foreign 15% tax and mortgage stress test in 2017 that drop prices and took just over a year to recover and bounce back..Don't look at appreciation  look at ratios, areas close to transit, if condos buildings not too older and higher than average maintenance fees..Converted duplexes are usually investors delight in Ontario and has been for years..

Nonetheless a combination of both have really helped me understand things.

Having all of this combined knowledge is such an amazing asset. 

I forget the numbers above you used for appreciation above by why not combine your strategy?

In light of a $12,000 bill, a $900 security deposit, an underemployed tenant, and an impotent legal system are a toxic combination. 

Which "concept" you go with, or combination of them (Lay out your plan with numbers) as you go through your plan, is going to be dictated by the numbers$ needed throughout your plan.

Assuming it is included, here is the full picture:1 - Annual CF = $13k2 - Walk away after sell = $160k (combined with partner)3 - # of years with perfect CF to get to flip profit = 12.5 yrsQuestion:  If you took the $160k from the flip, could you use it for a DP('s) on new deal(s) that would generate better than $1100 in CF per month?

This is a side hobby for me, as I have a day job outside of the US, so I'm focusing on a buy and hold strategy which will give me a reasonable combination of cashflow and appreciation, while using local management companies to limit my time commitment. 

Is there some way to combine our powers other than a BRRRR that we’re not thinking of?

Depending on the location of the property and its condition those should be at minimum 20% combined, probably more like 25% with COVID potentially causing higher vacancy in the near future.
