Well as I see it is subjective taste...
I like Robert Kioysaki:
https://www.youtube.com/watch?v=qCFoh-WBhusand before someone hater claims he is scammer I don't think so though I would not pay for his expensive courses. Please note that video is from a decade ago. Today's real estate market is tougher if you go for investing with thought oh my god this apartment will rise in value you might crash and burn very badly.
However I also like
David Ramsey
and most of you think that paying of debt is good. I agree.
That said consider this IF I take a new loan today I will NOT get so good loan agreements as I did a few years ago which was perfect timing for loan.
Instead of me taking a NEW LOAN with less good loan I can sell one of my apartments. Use all that money and buy another apartment or investing in something big.
Likewise instead of paying off very low interest mortgage... if you plan to invest big then saving money and using that is better then a new loan.
That said I also agree that pay of mortgage is good. Who of you wants to make the banks rich at your expense? Pay of mortgage slow as possibly and that is what you do.
This is subjective to risk taking...
You want to play safe? Do as David Ramsey tell you pay of fast mortgage.
You want to take risks? Take risks... but whatever is your fate if you become rich, wealthy, or do ok, or crash and burn... well I can not foresee the future.
For me there is a fine balance. Doing extra loan reductions is good for me, but IF I want to invest big then maybe it is time to save money and not been so keen on paying of mortgage very fast.
