No one wants to plan for a loss but it is always better to be prepared. US have recently seen a real estate meltdown that has caused the entire economies of the world to go into recession. So, it is very important to foresee such meltdowns and be prepared for losses. A second income source will ensure that you have enough rotational money to see you through losses.

Consider refinancing your mortgage if you haven’t done so in a while before interest rates go up further. Or consider leveraging cheap money responsibly to acquire hard assets. LendingTree Mortgage has one of the largest lending networks online, and they will contact you immediately with their offers. You want lenders competing for your business, and get hard quotes so you can pit them against each other.
Amazing that you saved between 50% to 75% living in NYC…I think that is one thing holding me back…the cost of living here. I’d like to invest in real estate, but I can barely afford to buy a place to live. I don’t need a large income to be happy, but I probably do need an income to support living in NYC as we don’t plan on leaving. The only thing I’m doing at the moment is saving in my 401K, IRA and a I dabble in stocks and P2P lending.
This is how the people who are in the 20% and 30% tax bracket can generate another stream of income by investing in accrual funds: The investor will invest in the fund and subsequently should also set up a systematic withdrawal plan (SWP) for the same scheme. The SWP will be set up in such a way that only the gains from the fund are transferred to the investor's bank account, at regular intervals, while the principal remains untouched. So in effect the investor enjoys a steady flow of regular income, but pays lower tax compared to if he had invested in bank fixed deposits. This is because as per tax rules, only the gains are taxed. While investing in accrual funds, the investment option should be growth and not dividend, financial planner and investors say.
The second category of passive income is drawing on sources that do not require capital to start, maintain, and grow. These are far better choices for those who want to start out on their own and build a fortune from nothing. They include assets you can create, such as a book, song, patent, trademark, Internet site, recurring commissions, or businesses that earn nearly infinite returns on equity such as a drop-ship e-commerce retailer that has little or no money tied up in operations but still turns a profit.

Great breakout of some common items that are (mostly) accessible to individuals. My biggest issue with p2p is the ordinary interest it generates and the ordinary tax that we have to pay. That really takes a bite out of the returns. Fortunately, I opened an IRA with one of the providers to juice the return with zero additional risk. 6-8% nominal returns over a long period of time will make me very happy. It should end up as 5-7% of the portfolio anyway, so nothing too significant.

However, I think for those who are willing to do what it takes, the sky is the absolute limit. As an example, I’m trying to take a page out of FinancialSamauri’s book and create an online personal finance and investing blog. It is an enormous undertaking, and as a new blogger, there is a seemingly endless amount of work to be done. That said, I hope that one day I can not only generate some passive income from the hours of work I have put and will put into the project, but I hope to be able to help OTHERS reach their financial goals.
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
