Better to do wholesale real estate or be an investor?

[Earl Jefferson]

Sort of stuck between a rock and a hard place. I'm currently overseas with the military, and when I get back, I want to put my money towards something useful. I have a budget of $30K liquid money for now to use. Currently live in Northern California, I'm limited in knowledge when it comes to wholesaling real estate as well, fees like I just need to see the process done for myself. So I pose this question, when a buyer doesn't have physical money, is there room for me to step in and lend my physical money, and gain a percentage when the house is sold?
