After attending different seminars on the topic of passive income, i have some ideas on my mind. The following sources of income may be the solutions under certain circumstances.
1. Rental income: given that monthly rental income is bigger than mortgage payment n the property price increases steadily
2. Forex investment: Manual trading requires skills n time. EA automatic trading may be the solution. Long backtesting procedure n enough capital are the pre requisites.
3. Online courses or YouTube video: Similar nature as you recorded video once, passive income can be generated.
4. Stock investment : Invest in some long term growth stocks or REIT. Stable annual income
5. ETF: such as SPY or QQQ these kinds of Exchange Traded Funds which have long term growth potential n low management fee.
6. Option strategies: Credit Spread or other.
