This is a good question on the (hidden) costs of owning a home, which is often neglected by many buyers when purchasing a property.
Owning a house not only entail the downpayment and monthly loan repayment, but also utility bills, maintenance fees and property taxes such as quit rent, parcel rent and assessment rates.
For serviced apartments, it does come with a higher cost as compared with typical residential apartment/condominium.
This is because service apartment often come with housekeeping facilities, room service and so forth, which entail a higher maintenance charge every month. Also, as serviced apartments sit on commercial land, owners have to pay commercial rates for utility bills and property taxes too.
As you are buying for own stay, you are advised to find out all these hidden costs before you make the purchase.
