It’s a (mostly) short term, higher risk, higher reward place to invest cash that has a low correlation with the stock market, but is far more passive than buying and managing properties, has more opportunity for diversification than private placements (minimums of 5-10K, rather than 100K), and most of the equity offerings (and all of the debt offerings) provide monthly or quarterly incomes. Unlike a REIT, you can choose exactly which projects you wish to invest in.
Renting value is exactly what you do when you go to work every day. This is a great way to adhere to our rule against one-time consumption, although you can only rent something to one person at a time (drawback). By renting something, I can generally avoid degradation of the value, or at least lessen it. By renting you a house, I’m charging you for the value of the shelter and comfort, and in fact incur pretty minimal decrease in value as your usage of the house causes wear and tear. When you’re done renting the house, there’s still plenty of value left to rent out, and the fact that you’ve enjoyed a year or two of value doesn’t much matter to the next willing consumer.
* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances. They’ve also got great tools for x-raying your portfolio for excessive fees, recommending a more optimized asset allocation, and planning for retirement with their Retirement Planner.
