6.9% is a great interest rate nowadays. I wouldn’t worry about trying to pay that off unless you can get another loan for better. Use your savings to make your money work for you. 42k is a great stash to sit on. Take a 1/4 of that and learn about options trading. Selling premium can generate income if you understand bet sizing. Tastylive on YouTube is a great resource. Manage your risk properly and you’ll continue thriving. Good luck.
It depends. What yield are you earning on your savings? If you’re making 5%, you would make approx 650. But you’re paying $900 in interest (ignoring the compound effect) Overall I’d say you’re likely better off paying it, but if you have a tiered interest and you’re making over 6.9% on your savings, then I’d recommend you stay your current course
