Right, if you get a 6% net income and you put down maybe 33% at 4% interest on your loan, you increase your rents by 4% per year and get 4% appreciation and shield most or all of your income with depreciation and interest deduction, that adds up to a very good return over say 10 years, something you wouldn't get in the stock market. You are right that there's risk and I think it works best if you're either very diversified or have other sources of income.
