Amenities and the location of the apartment will make it more expensive. For instance, it is cheaper to get an apartment in the centre of the building, as people generally spend more to occupy the top or ground floors. The amount of bedrooms and bathrooms will affect the rent or purchase cost, so think hard about the extent of space you require to live comfortably. When it comes to location, the more central it is, the higher the prices. For example, apartments for sale in Colombo 5 will be more expensive than in the suburbs like Battaramulla.
