The Rentista Visa (Private Income Retiree) is really for those retirees who were self-employed, who owned their own business or may have received a retirement lump sum, rather than monthly pension payments. If you make a five year term deposit at Panama's Banco Nacional that will generate a minimum of $750/month in interest, you (and any dependents) are granted a renewable temporary residence permit for five years. The monthly interest earned would be deposited directly into the your savings account and the you can withdraw the funds in the savings account at any time.
