Should I put more money down on one property and pay it off sooner or hold on to the cash?
I'd suggest taking all the money you have saved up and putting in a mutual fund and hold off on buying a rental property until you can buy it outright.  I know it seems like this will take forever, but it has a HUGE advantage: I know it seems like it will take forever to save up the money to buy a property for cash, but in the long run, its the best option by far.
