I would just add it to My investment portfolio and watch it grow.I already own a home and another property,so I would put it in stocks and bonds.Actually,$400,000 is not that much money if You are not careful with it.I worked with a young man that inherited $600,000 and blew it in 3 years on cars,more cars,electronics,big screen TVs,Women,booze,and assorted other vices.-----I would have some fun with it,sure.."found money" so to speak.But I think about the fact that those of us that are younger than 40 will probably never see a penny from Social Security,so I would add most all of it to investments.
