Should I put more money down on one property and pay it off sooner or hold on to the cash?
I would go with the 2nd option (put down as little as possible) with a small caveat: avoid the mortgage insurance if you can and put down 20%. Holding your rental property(ies)'s mortgage has some benefits: You can write off the mortgage interest.  In Canada you cannot write off the mortgage interest from your primary residence. You can write off stuff renovations and new appliances.  You can use this to your advantage if you have both a primary residence and a rental property.  Get my drift? P.S. I do not think it's a good time right now to buy a property and rent it out simply because the housing prices are over-priced.  The rate of return of your investment is too low. P.S.2.  I get the feeling from your question that you would like to purchase several properties in the long-term future.  I would like to say that the key to good and low risk investing is diversification.  Don't put all of your money into one basket.  This includes real estate.  Like any other investment, real estate goes down too.  In the last 50 or so years real estate has only apprepriated around 2.5% per year.  While, real estate is a good long term investment, don't make it 80% of your investment portfolio.
