The price difference is mainly due to the age of 123 Lorong 1 Toa Payoh, which is an older block with only 3-room flats, versus a wider range of unit types and ages for HDBs across Toa Payoh. Generally, flats in 123 Lorong 1 Toa Payoh are less expensive than the average Toa Payoh resale flat, particularly when compared to new or larger units in the estate.
