$30k to invest...New to investing...

[Cory Blum]

Hello,

My wife and I have saved $30k and are currently accruing %12 APY via hard money loans through her grandfather. Her grandfather lends a larger portion of money to house flippers and has first position on any returns on the houses. Seems like a safe investment, however, it is very steady or . It is simply based on whether or not someone is in need of the loan and the length varies from 5 months to a couple of years at which point we have to cross our fingers for the next loan. Not to mention the connections are all through her grandfather who won't be around forever. We are in our mid twenties with no kids and are looking to perhaps be a little more aggressive with our money. Perhaps something with a little more risk with and in turn, a higher yield.  We are currently able to save an average of $2,500/ month and would like to continually invest that as well. Any advice would be greatly appreciate as we have little experience in this field having started from the bottom, if you will.
