We have a gift of a substantial amount of money (in USD) that we would like to invest. We want to stay away from interest as much as possible but would still like to significantly increase the amount. If there are few ways to go about it without recourse to interest, please tell us how we can use interest to our advantage.
One option is buying real estate, and we are still thinking of that.
Other options? We are in the student/early-career phase and new to these considerations of money, thus ignorant as to our options. Any and all help appreciated.
If it is significant, we are in Canada. Thank you.
