The price difference between under construction and ready to move properties can vary widely based on the location, developer, and specifications of the property. Typically, under-construction properties are priced lower than ready-to-move properties due to the wait time for completion and the risks associated with the construction process. The difference can range from 10% to 30% or more, depending on market conditions and the stage of construction at the time of purchase. Buyers are encouraged to research specific markets and developments to understand the price dynamics better.
