The Rhine Valley continues to lead St. Gallen in real estate supply, with a 4.6% supply ratio despite a slight decline in condominiums. While new single-family home construction is decreasing, prices remain high, with a 2.2% increase to nearly CHF 1.6 million, and condominiums rising 4.8% to around CHF 910,000. Strong population growth and rising demand are expected to sustain price increases, although economic risks from international companies may affect buyer willingness.
