Some of the advantages of owning a condo:
NO EXTERIOR MAINTENANCE, NO CUTTING GRASS NO SHOVELING SNOW. Covered by association fees. (check what they are)
Some have attached garages, usually under the unit. The economies of scale usually make them less expensive than similar sized single family homes.
With a single family home you bear all the costs of exterior maintenance. You have to cut the grass, pick up the trash that blows into your yard from who knows where. Some subdivisions have association fees (just for living there and you get nothing for it). I pay association fees based on the number of lots and then I pay someone $100 a month to mow the grass. I have to shovel the snow in my driveway. (well use the snowblower anyway)
