Flex-term letting allows landlords the ability to list their property as a short-let, mid-let and long-let. For example; if you had a tenant exercise their break clause at 6 months, you could quickly list the property on a short-let platform and avoid any loss in rental yield. While the property is earning short-let income, you can list it as a long-term let and, once tenants have signed up, switch it back to a long-let contract.
