Either. If the property is bought for hopes for selling when the property appreciates in the future and when there is and sold, it will be considered as an investment. If the property is used to generate profits, e.g. rental, using as an office space, it will be viewed as an investment. For me, I will view my parent's home to be somewhere to stay. If I were own my own house I will consider it somewhere to stay too. Unless if I were to operate a own business from home or renting it out to have rental income, I will view it as an investment.
