If you want to play with the variables, you can take a look at an excel spreadsheet I created here. You can modify the price-to-rent ratio, forecast real estate and investment portfolio returns, tax rates, realtor commissions, and more. You can even model non-linear returns. In other words, what *could* happen if there was a real estate correction? Crash? What if the investment portfolio tanks, or has a lower/higher long term rate of return.
