However, just as many said they would undertake those sacrifices willingly and even take such steps as to live more frugally (62%), pull money from retirement or other savings accounts (50%), retire later (35%), take on debt (31%) and even refinance a home (13%) to help their adult kids out.Conditions of SupportWhile supporting adult children is undeniably generous, many parents did say they put conditions on their offers of support.
