depends on your tolerance for risk and the amount of elbow / eyebrow grease you'd like to invest on top of your money..
Low risk, low maintenance real property/land
obviously more conservative gain, and less liquid.
Higher risk, greater demand on time/effort, quicker $ brand new equipment… furnaces, pumps, motors, etc.. they're going to keep going up.. supply chains going to have many opportune back-ups.. just need to rent some storage, manage it, develop some relationships with some local contractors, get a feel for whats most viable..
