Depending on how large of a bet this is with your friend you can consider real estate. I don't know the technicalities of the bet but you could get a 0 down loans on a house put 2K into cleaning the place up and get some renters. Depending on your market the house might increase in value by 75K. Otherwise you could sell it in the spring-summer season where the market is almost always hotter than winter. Take this cash you make and try to turn that into 75K.
