Earnest Money Deposit (EMD) is a buyer’s upfront payment to signify commitment in a property purchase. Double Closings involve two back-to-back real estate transactions on the same day, allowing for swift property turnover. Transactional Lending, or flash funding, offers short-term financing for rapid real estate transactions, commonly used in scenarios like double closings. This type of lending bridges the gap between the initial purchase and subsequent sale, enabling investors to maximize profits.
