There's no standard credit score needed to lease a car. However, you stand a better chance of being approved for a lease with a favorable interest rate if you have good credit or better. On the FICO scoring range, that's a score of 670 or above, though lenders may prefer a score of 700 or above.
Florida is a state with a high volume of cars due to its large population and tourism industry. Many rental cars are sold after a few years of use, which increases the supply of used cars in the market. This high supply often leads to lower prices for buyers.
