Three things explain most of the gap between two nearby houses:
- The living area and the size of the plot: they set the starting point.
- The condition of the house and the age of the roof, windows, wiring and heating.
- The EPC, which shows how much energy the house uses.
The exact location within the municipality matters too. Only a visit shows the flaws and strengths that figures miss.
