Using a storage facility to place your goods for a short or even a long period of time can be a very good idea, and there a number of compelling reasons why this is the case.
One reason why using storage is a very good idea is that your space is worth more than the cost of a storage facility. Depending on your living situation and your location, you could make money by having a spare room cleared out, placing the contents in storage and then renting that room out. Putting the average contents of a spare room into storage may cost you a good amount per month, but renting that room out could earn you money within that same period of time.
A storage facility can also be very useful if you are building a new home or renovating your existing property. Putting your household goods into storage while this is going on means that many of your valuable assets are protected while work is being done on another asset. This will obviously only be a temporary storage situation but it can nonetheless be a very important one.
Storage facilities can also come in handy in inner city areas. If you own a motorbike, quad-bike or boat but live in the inner city, there may be no room to store it on your property; in this case, it would be far cheaper to put it in storage than risk parking it on the street and having it stolen.
