Real estate investors are individuals or groups who purchase properties with the intention of generating profit. They may buy residential homes, commercial buildings, or land, aiming to either sell them at a higher price or earn rental income. Their investment strategies can vary widely, from flipping houses to long-term rentals. These investors often conduct market research to identify profitable opportunities and may work with professionals like real estate agents and property managers. Successful real estate investors typically have a good understanding of the real estate market, financing options, and property management practices to maximize their returns.
