Rental yield measures annual rental income as a percentage of a property’s value or purchase price. Gross yield is rent divided by price before costs; net yield deducts running costs (ground rent if any, maintenance, letting fees, void periods) first, and is the more realistic figure for comparing investments. In Malta, yield doesn’t track price level directly - premium Northern Harbour localities often have lower gross yield than more affordable areas with strong rental demand, since entry prices are higher.
