I just made $50K from selling my house. How should I invest the proceeds?
First pay off all existing debt. Then set up at least 6 month emergency fund.  Freelancing exposes you to way more risks than employment. Then buy GIC's to cover and match the maturity of  your expected education fees. Only 'play' with what is left.  Don't over think it.  Buy a low-cost (less than 0.5%) passive large-index mutual fund covering either the S&P or TSX.
