This is entirely up to you. But rather than researching the item’s replacement cost and applying that, give some thought to two primary factors. Firstly, the higher your deposit charge the less appealing it will be to renters. It may seem just as financially viable for them to purchase the item themselves. Secondly, assess the item’s condition and importance to you. Even if it’s in excellent condition, how long have you owned it? Is it valuable to you for sentimental reasons? Is it easily replaced or is it a hard-to-find item? These factors, rather than a like-for-like deposit value should influence the deposit you apply, particularly as our experience indicates that smaller, fairer deposits will result in more rentals and for a longer period of time.
