Long term loan vs short term strategy

[Richard Hadley]

I'm just curious what other investors prefer and why. Some of my local gurus are recommending that long term loans (mortgages) are better because they get more of the profits right at the start rather than waiting for the property to pay for itself to get a better return. Then there are others myself included that are paying my property's off in 5 years. Getting a better return after. My property's have an roi average of 20%

Just want to hear your thoughts.
