how to start with 15k cash

[Alisha Solache]

I'm just curious what is the best way to invest 15k. We want a way where we can keep going. Was thinking of getting a land contract property, do basic work to it, and land contract it out to another person. Have them pay 5-10k down, and use that money to keep the investing going. 
Does this sound ok? Any tips or better ideas of a way to roll the $? 
TIA.
