Valuation of real estate is required for a range of endeavours such as sales listing, financing, property insurance, taxation, and investment analysis; however, for most people, determining the purchase price of a property is the most helpful factor of real estate valuation. Since apartment projects in Sri Lanka carry unique features like floor plan, location, lot size, and amenities, valuing real estate at first glance can be difficult, but concepts such as supply, and demand of a given area will certainly factor into deciding the over-all value. Individual properties are usually subject to appraisal methods such as the sales comparison approach and the income approach.
