On the contrary, a ground floor will sell for up to 25% less than Similar accommodation in the same building but located on the 4th floor. Count 30% Discount if the dwelling is to be renovated in its entirety and up to 10% If it is badly arranged (chambers in a row for example) or badly distributed (one Large entrance followed by a small lounge).
