What are the approximate costs for use of portable storage units?

That depends on what size and for how long you need the portable storage unit. The best option would be to contact the different companies in your area and get quotes from each of them. Here is a list of the most common companies that offer portable storage units:

How much you are charged can vary pretty substantially between the companies. Consider the following:

* How much are the delivery and pick up charges?

* How much time do you have to pack the pod (once it is delivered?) Read the fine print of your contract, as even a day or two over your scheduled pick up time can result in higher costs * Can you access the storage if you need to at no cost?

* What is the cost per square foot/inch of storage? The size of a provided storage pod can vary between companies * Do they charge you for ALL pods that are delivered or do you just pay for what you use? * If you need to break your contract, what are the penalties?
