You need to actually look at the property and it’s condition.

I’m currently in the same boat🚣♀️, having been self-employed for most of my adult life.

Buttttt it all depends on the area, kind of tenants, condition of the properties etc....

If it is a flip, also include your goals, condition of property, etc.

Selling land to contractors (not sure yet about the market conditions yet)3.

I'm biased though because I have lived in middle/upper middle class area my whole life and would never live in a lower middle class/low class neighborhood area.

Just diversify your portfolio a bit.Then youd be able to live off the cashflow from your 3 other 4plexs, since you have no living expenses, yes you wouldnt be rich or anyhting but you could live a comfortable frugal life without having to work.This way you'd have money thats fairly liquid as well in your TFSA, in case you had to do any repairs or to account for miscellaneous problems that could occur, and in the very worst case you could do a HELOC  to pay for any major major disaters that could occur with all the equity youve created in your home by using the BRRRR investment strategy.These numbers are just examples, however its not unheard of to BRRRR a property and actually come out with more cash than it cost for the DP and Renos, which would help acquire even more property.And if you can get 50K into your TFSA and get a return of 8% from a dividend then thats an additional $350/month roughly, all while living for free. 

If you are good with people, focus on getting into a restaurant, possibly work for a local pizza delivery and stow away AS MUCH MONEY AS POSSIBLE (Go read Set for Life).

The seller is willing to owner finance on conditions a regular lender would not touch.

Of course, the condition may not be top notch, but all look inhabitable while you work on them.
