Both indoors and outdoors, you will probably have more space if you own your own home. Even moving to a condominium from an apartment, you are likely to find you have much more room available – your own laundry and storage area, and bigger rooms.
Apartment complexes are more interested in creating the maximum number of income-producing units than they are in creating space for each of the tenants.
If you are moving to a home for the first time, you are going to be very pleased with all the new space you have available. You may have to even buy more "stuff."
