Real estate investment can be a valuable part of investment portfolios, offering potentially high returns. The real estate market is unique, with properties not traded on a centralized exchange, leading to less liquidity and higher transaction costs. Limited data availability means appraisals are often used to analyze returns. Investors who can access quality information may benefit from the market's lack of transparency. Overall, real estate investments can provide a source of risk-adjusted returns for those who understand the market dynamics.
