Flipping houses involves purchasing a property, making improvements, and then selling it for a profit. Investors often look for homes that need repairs or updates, allowing them to buy at a lower price. The goal is to increase the property's value through renovations, such as updating kitchens or bathrooms, improving curb appeal, or fixing structural issues. This process requires knowledge of the real estate market, renovation costs, and potential resale value. Successful house flippers often work with professionals like contractors and real estate agents to ensure that their investments yield a good return.
