One factor to consider is your home. Many people consider downsizing when they retire. Many more choose to age in place. There are many factors beyond finances to consider when making this decision. From a financial standpoint, downsizing can, but not always, save more expenses.
Before downsizing one needs to consider where one will be living and if the costs there will be lower. Research the possible new location and speak with other owners in the area to determine how this move will affect your spending.
You may be able to rent some of the space in your home should you choose to remain in your present home. This option depends on many factors including whether you want to have someone else living in the home.
Either way it is good to have options to consider for retirement expenses.
