I have already come up with 50 ways that a management company can screw you for profit without you ever knowing(or not finding out for awhile). Did you have an inspection before you made an offer on the property? Do you have a picture of the property you bought? How do you know if that picture shows the house you actually own? or if it even hows the ‘current’ state of the house you own?
The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income. It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate." Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth. Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices. In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
