My DD will be a freshman at a private university this fall. Although we have multiple (out of state) 529 accounts, they will not cover the EFC for all four years. We are not eligible for any financial aid beyond a single grant given by the University to cover the difference between COA - EFC. What is the best strategy for using the 529 funds we have? Should we use them all up-front to cover the first two years and then plan to take out parent loans? Or should we divide the money equally across the years? Another complicating factor is we have another child starting college in two years and that will change our EFC again.
