You have a mortgage and donate most of your income ... why?
Although I'm holding off on investing for now. Sold some of my 'play' money stocks (tesla etc) and put it in trackers. Might sell off those too and just wait it out a bit.
Why? There's some good reasons to pay off a mortgage early:
1. You pay less interest, so you pay less in total. Don't worry about the tax rebate; it's only giving you back maybe 10% of your payments.
2. A mortgage is a loan. Fewer loans means less risk. Your house can't be foreclosed on if it doesn't have a mortgage.
3. Afterwards, you have an extra $2,000 every month, because you're not sending it to the bank. Your expenses (burn rate) goes down, so your savings will last longer if you lose your job.
