I see it as a gamble, and not an investment.

Anything less than that is risky and gambling.

To me it would only make sense to keep your current property if you believe there will be more price appreciation on this property than another one you could buy with more cash flow, but that's a gamble.

@Gamble LiAround here (Fredericton), the inventory on 6-10 unit buildings is pretty tight  - though there are a couple for sale at the moment in a part of the City that is a little less desirable.  

Our biggest challenges are 1) tenant friendly (impossible to increase rents to keep pace with market) 2) High price per door 3) Poor rent to price ratio  If your approach is to gamble on appreciation, Metro Vancouver may be a fit, but I've found better overall returns elsewhere.

Stock and crypto are legalized gambling, as far as I am concerned and, like @Scott Trench, I am sure glad that my retirement is based heavily on real estate. 

Banking on appreciation is gambling

Investing for appreciation only is gambling.

1) Buy a business that suffered during COVID but has sound non-pandemic fundamentals2) Buy in markets where cap rates still make sense (i.e. not Canada)Investing for the hope of appreciation is not an investing strategy, its gambling. 

I'll chime in.... this strategy isn't investing, it's gambling.
