Here is the mathematical equation:Assets x ROI = Cashflow > Expense BudgetHere are the steps:Determine you annual Expense Budget based on how you want to live.Example: $75K/yearDetermine your Return on Investment based on your Risk Tolerance.Your Risk Tolerance is based on how wiling are you to risk losing it all when it comes to your incoming producing properties to where you would have to go back to work.Use a scale of 1-100, 1 = cash in mattress and 100 = I'm gambling the rent money a the craps table.Take your Risk Tolerance # and divide by 5 to calculate your ROI.Example: Risk Tolerance = 50, ROI = 50/5 = 10%Income Producing Assets = Expense Budget/ROIExample: $75K/10% = $750K in income producing assetsFor real estate, Income Producing Assets = Property Equity, not the market value of the property.
