I'm considering investing via one of these or similar sites. Has anyone had any experience with this? What are the pro's and con's? We have some money to invest, but we also have careers that we love and want to continue. We prefer low maintenance investments. That said we're concerned about contracts that don't let us sell when we want or then flipping in areas that may not hold value well. I know there is always risk, but some areas almost always have demand where that may not be true of other areas. I'm interested in talking with someone who has done this.
