If you were to look at a condominium and an apartment block you would not think there are many differences apart from the outside of a condominium would look a bit better. They are quite similar in the way they look but are run and managed in completely different ways and the legality of the ownership will be different. It gets quite complicated with the small print which is why it is always important to get someone with legal knowledge to look it over.
Apartments are owned by individuals where you are free to do what you want with your apartment and are not governed by any boards. Whereas condominiums are run by a board and keep tight rein on what happens even in the apartments themselves. Some may find this quite restrictive whereas others will like the order and protection a condominium can offer. If you own a property in the block you will need permission to change the shape, type or whether you can have pets. Apartment blocks will tend not to be managed at all which can effect the price of insurance.
As condominiums are run by a board they tend to know more about the relevant insurances and necessary documents to keep everyone safe. With an apartment block if there was a natural disaster or damage to the building it maybe up to the individuals living there to cover the cost as there would be no one else to do this. You will have more piece of mind living in a condominium then in a apartment block as there will be overnight security. This has been proven to lower intruders and burglars and to generally keep the place a lot safer. They will always explain the condo insurance coverage that is needed to protect your own individual unit.
