Investing in real estate vs peer to peer lending

[ScottRUnderwood]

I already own a house in bay area. I have about 30K extra in cash sitting in my savings account. This is not part of my Emergency funds. I maximize my 401k, my house loan is 4% and I have enough Emergency funds (6 months of mortgage). I have been researching a lot (in this forum) about alternate investing strategies and I am narrowed it down to either peer to peer lending or investing in another house.

1) If real estate is the correct strategy, should I buy another house in bay area itself or different part of the country (to diversify)
2) Instead of just buying another house and give it to rent, any suggestions of putting in real estate so some other company manages the property or something like that.
3) Should I just do peer to peer lending and invest all the money there ?

I think you should invest in a house first it will provide you a fixed monthly income and when you have enough saving again then you can invest in peer to peer lending also, doing like this can provide you seedy and ideal growth in your money.
