Whether you're living on campus or subleasing your room for the summer, you'll need to find a place for your things. And if you aren't able to move all of your things home each summer, that might mean renting a storage unit.
According to data collected by storage unit rental site SpareFoot, the average cost to rent a storage unit across the US is $88.85 per month. But, that varies by your location.
While the average cost to rent a unit in Indianapolis is $63 per month, units in denser urban areas like Boston and Los Angeles will cost about $140 per month. Multiply that by the three months you'd need the unit for the summer, and storing your things could easily cost upwards of $400.
To cut back on storage costs, find someone who'd be willing to split the costs of the unit — you likely won't have enough to fill the whole space yourself, anyhow.
