Oftentimes family and friends are experiencing space constraints simultaneously, especially if downsizing to a condo or apartment, or even if just decluttering your existing space but are not ready to part with belongings that still have sentimental value.
An excellent cost-saving solution would be to share a unit. Discuss what sorts of storage space needs you each have and if you and a family member or friend decide that it makes sense as an option to invest in a unit you can share, you can choose the appropriate unit size and decide how to divide up the space and split the cost.
