Real estate is often thought to always increase in value and provide high returns, but this is a myth. While real estate prices have risen in some areas over long periods, they can also decline or see low appreciation in other areas and time periods. Real estate is an illiquid investment compared to other assets, and selling properties during downturns can be challenging. Overall, real estate does not guarantee high returns and investing solely in real estate risks losing money if not done carefully after understanding market conditions.
