How to decide as a retiring senior citizen whether to buy or rent
Consider how long you plan to stay.
One of the first things you should take into consideration when you're deciding whether to rent or buy a home after retiring is how long you plan to stay. The shorter the stay, the fewer benefits you'll receive from buying a new home.
As a general rule, if you plan to stay in your new home less than three or four years, renting is going to be a better option. Think about your must-haves.
