How funny! Dh & I were just saying how much we enjoyed our condo. No shoveling snow, cutting grass, etc. Heck we didn't even own a hose or lawnmower. In spring, we'd come home to see flowers planted. Pool was included. We bought it in 93 and stayed for 3 years before buying our single home we're in now.
It is a lot of maintenance because it was built in the early 60s but luckily dh is extremely handy.
We have agreed if one wants to be a homeowner, he/she either needs to be very handy or have plenty of $ to pay for maintenance. Unfortunately, his sister was in neither of these categories, insisted on a single home which needed a lot of work by the time she sold it.
The only negative I can think of was that there were so many rules living in a condo. When decorative flags first became trendy, they were banned.

Also when the condo association first stated that people could get screen doors, they had to be purchased through the association and have them install it too. They wanted $300 and dh was peeved that it wasn't such a high quality door to justify the cost and he could install it himself and save $ but they wouldn't let us. Understandably, they wanted all the doors to match but still, it was frustrating. Our condo didn't have a garage so if we ever go back to a condo/townhouse, it will definitely have a garage, preferably 2-car. That was top on my list of requirements when shopping for a single, besides central air.
We had an apartment for 1 yr before the condo and that was our least favorite place. Sure no maintenance but many renters (not all) are not very concerned about keeping a place looking nice. Homeowners have more invested in their home or condo so they tend to put more effort into taking care of the place though not all do.
