Each person has different objectives and goals. For most paying off the debt is the way to go, it "helps them sleep at night".
For me, I would never pay off, make extra payments, take out a shorter term loan, etc... for any real estate. I can make so much more buying income producing assets than the "saved" interest by having the mortgage gone. Many will say that if something happens and I can't earn then at least I own my home out right. Think about it, if your lose you ability to earn you likely can't pay your taxes and you can still lose your house.
If you have the ability to source RE deals where you can hit between 15-20% IRR that's a lot better use of the funds that you would have used to pay something down quicker or off entirely.
If you take the money you would have used to pay off or down a mortgage and instead you save to buy income producing assets, the income they produce (provided of course you have cash flow) will eventually cover the entire monthly mortgage payment for you and you now have an underlying asset that still has the ability to appreciate.
This is just MY approach and I realize many will think it's CRAZY and that's OK.
Regarding debt, I would definitely pay off consumer (credit cards...) debt as soon as possible but not the mortgage.
Find the people around you that have the life you want and do what they are doing. If you just want to have your bills covered find a person that has done that; if, however, you want to a BIG life you need to change the way you think with regard to finances. Find the multi-millionaires you can and look at how they are going about it, it's usually not paying off any RE, personal residence or investments, they will always look for ways to unlock equity and put it to use buying even more income producing assets.
To each their own.
