One of the main reasons people choose condominium living is for the convenience. There is no snow clearing or lawn care or upkeep that the individual unit owner has to worry about. All of that is taken care of by the Board of Directors and Management Company who take care of day to day issues.
Safety & Security
Safety and security runs a close second to convenience. If your choice is an apartment style condominium building, you will be living in a secured building accessible only to the occupants, and when you leave to go away you do not have the same security issues as if you were leaving a conventional house.
Maintenance & Upkeep Expenses
Maintenance and upkeep expense is spread out over the long term in the form of condominium fees whereas in a house there is normally a large outlay of expense when something like roof or windows need replacement, and in most cases (in well run Corporations) there are no surprises and you can feel secure in knowing that you always know what your household expenses are going to be.
Condominiums are attractive to first time home buyers, busy executives, and seniors downsizing. There is generally less space to furnish and less housework and no grounds keeping.
You may lose some privacy, in that, you live in very close proximity to your neighbours.
