MY SPOUSE AND I ARE EACH 62 AND HOPE TO RETIRE IN THREE YEARS. AFTER RETIREMENT WE WILL RECEIVEE 7500 PER MONTH AFTER TAXES FROM OUR EMPLOYERS PENSION PLANS AND 1500 PER MONTH AFTER TAX FROM SOCIAL SECURITY. UNFORTUNATELY, OUR MONTHLY EXPENSES ARE 15,000. OUR SOCIAL OBLIGATION PRECLUDE FURTHER ECONOMES. WE HAVE 1000000 INVESTED IN A HIGH GRADE, TAX-FREE MUNICIPAL-BOND FUND. THE RETURN ON THE FUND IS 3.5% PER YEAR. WE PLAN TO MAKE ANNUAL WITHDRAWALS FROMT HE MUTUAL FUND TO COVER THE DIFFERENCE BETWEEN OUR PENSION AND SOCIAL SECURITY INCOME AND OUR LIVING EXPENSES. HOW MANY YERS BEFORE WE RUN OUR OF MONEY? WHAT DO YOU TELL YOUR CLIENT?
