There are many advantages and disadvantages to leasing a horse. Depending on your situation,you can decide whether leasing is a suitable option for you. The most common reason a person would lease a horse instead of buy one is that leasing allows you to experience the joys and responsibilities of horse ownership without actually having to deal with certain liabilities. If you desire to work or ride a horse more frequently than a few times a month but may not have the finances or the property required to own one, leasing is a sensible option for you.
