Are off-plan properties generally considered to be a better investment than finished property?
It depends if you want a return immediately or if you are willing to wait a few years. If you are willing to wait then the off-plan option is usually much more profitable as you can buy the property at a discount price and not have to pay a mortgage while the property is being built. Also off-plan property will be brand new when completed and wont carry the problems many older properties carry.
