I'm not looking for no market risk. I could achieve "no market risk" by just paying off the mortgage now. A 5% to 7% return requires some risk (obviously). A straight equity investment (such as a no load index fund) would theoretically yield a 10% return over the long run, but the variabily of such an investment is too high for what I have in mind and a 5 year time frame is too short to reasonably target a 10% return overall. A common stock equity investment would however defer taxes until I cashed out the investment (assuming capital appreciation and no dividends) and it would generate a long term taxable gain.A 5% to 7% return on an "equity" investment would be a relatively "safe" return by market standards (half the long term average return on US stocks). I'm just looking for ideas here. Preferred stock? Asset backed securities? Hedged equity investments?
