Real estate investment or Pay off debt?
I would say that if you're current on your mortgage loan and confident that you'd be able to pay it back right on time, you can invest your amount from where you can get profitable returns. But, ultimately, it's your decision.
So, you have a decent paying job and a good amount saved in your account..right?
As per my opinion, you must go for paying off your debts in the first place. Save and secure your existing home before reaching out for another real estate investment.
Your income is steady, and you're unmarried. So, your monthly expenses might be less than any other married person. To manage your monthly expenses more effectively, you should make a budget plan and live accordingly.
So, what you need to do is to save as much as possible for emergency, grow your wealth, pay off your mortgage, and as soon as you get your mortgage cleared, go for other investments.
Hope that helps.
