Living in a condo is neither more expensive nor less expensive than living in a single family home, all told. It is, specifically, a life-style choice.
For example, we don't have to spend time to cut our lawn, prune our bushes, etc. Nor do we have to spend the money necessarily to have our landscaping done for us, nor do we even have to spend the time and energy necessary to pick a good landscaper, monitor their performance, interact with their bookkeepers, etc. All this convenience we get, in terms of the service our condo association provides us as it regards landscaping, are of great value to us, and therefore we yield a lot of profit from the relationship.
By the same token, if you want to pick your own housepaint color, or decide which flowers get planted, or if you want to hang random signs on your property, etc., then you really don't want to live in a condo.
