"Downsizing Downsides" by Wade Nkrumah

Basement.
Garage.
Closet.
You’ll have the latter when you move into your condominium. And you’ll wish you had at least one of the former two, which is what you’ll miss most when you downsize from your house to a condominium.
Even in houses, there’s often not enough closet space. Thus, basements and garages function as catchall storage in a great percentage of houses.
Therefore, if your house has a basement and garage, your what-I-miss list doubles in size when you trade your house for a condo. In most cases, closet and storage space in your condominium won’t double.
Lack of seemingly adequate closet and storage space can be the biggest downside to condominium living. So, if you’re a collector or a pack rat with hoarder tendencies, you’re going to have to curb your enthusiasm or stay in your house with the basement and garage.
Of course, there are creative storage solutions a plenty, even for the smallest condominium space. And – you guessed right – they come at a cost.
So, the smart condominium shopper puts closet/storage on a par with that which he or she considers the single most important living component or space.
For many, it’s the kitchen. For others, it’s high-ceilings. For her it’s the living/dining area. For him, it’s the wall of floor-to-ceiling windows.
Whatever is deemed most important, the priority mindset when looking for a place should be, for example, kitchen and closet/storage or floor-to-ceiling windows and closet/storage.
Most everyone needs space for computer/electronics packaging, fitness/recreational/sports equipment, suitcases, and miscellaneous collectables.
Thus, if having a place to store those skis or surfboard is a must, the condominium at the top of your list might be the wrong fit if there’s closet space only for your clothes and no other storage space in the building.
Many condominium buildings have additional storage space, but many don’t. As for garages, unlike in your house, the assigned spaces in condos are for cars, not storage.
