Should I put more money down on one property and pay it off sooner or hold on to the cash?
My figuring (and I'm not an expert here, but I think this is basic math) is: Let's say you had a windfall of $1000 extra dollars today that you could either: a. Use to pay down your mortgage b. Put into some kind of equity mutual fund Maybe you have 20 years left on your mortgage.  So your return on investment with choice A is whatever your mortgage interest rate is, compounded monthly or daily.  Interest rates are low now, but who knows what they'll be in the future.  On the other hand, you should get more return out of an equity mutual fund investment, so I'd say B is your better choice, except: But that's also the other reason why I favour B over A.  Let's say you lose your job a year from now.  Your bank won't be too lenient with you paying your mortgage, even if you paid it off quicker than originally agreed.  But if that money is in mutual funds, you have access to it, and it buys you time when you really need it.  People might say that you can always get a second mortgage to get the equity out of it, but try getting a second mortgage when you've just lost your job.
