The statement is strongly supported by the evidence. Multiple sources, including Reuters (Evidence 15) and Trading Economics (Evidence 3, 5, 10), corroborate that U.S. new home sales reached 800,000 units in August. Evidence 15 explicitly states a 20.5% jump, which is consistent with the increase from July's 664,000 units mentioned in other sources ((800,000 - 664,000) / 664,000 ≈ 20.5%).
