All people and families need to have an emergency fund even if you think you don’t. After you have paid your debt off you need to start an emergency fund in case something happens and you are unable to work for several months. You should not even think of saving for a house until you have at least 6 months worth of living expenses saving in an emergency fund.
Start putting that money in either a high-interest savings account like ING or HSBC. Another good way to put money away for a rainy day is to put it in a money market. Banks and mutual funds both have money market accounts so try Bankrate.com to compare what interest rates are available.
