I love this concept, how do I maximize the money I generate from my unused space?

We love that you love Storzzy, our research shows that smaller storage units generate the best price per square foot, so if you have lets say a 2 car garage that is 10' x 20', don't rent it out as one singular space for $400 per month, subdivide that 200 sqft into four 50 sqft units, charge each of those parties $200 per month, and generate $800 per month. There are racking companies that you can hire to build securable cages that your individual tenants can access. With a small upfront investment, you can turn your empty garage or basement into a little cash cow. (See Wirecrafters.com and securitycaging.com for just a couple of options here in the GTA).
