How do I buy a foreclosed home?

My boyfriend and I are going to be moving back to California soon and we were looking to buy a foreclosed home. We don't have any money saved but we've heard that you can buy foreclosed homes with no down payment. You just take over the payments on it. Is this true? If not, can you tell us how to go about buying one?How do I buy a foreclosed home?
You heard incorrectly.

You have to get a mortgage and the lowest downpayment you can do right now is with FHA financing and if I am being totally honest, foreclosures are HARD to get approved by FHA. I am going through it right now and its been a CHORE...lots of work and time invested but its working in the long run. FHA has strict rules about the condition of the house so if there are problems with the house they could flag it and your financing would fall apart. Conventional mortgages right now require 10% down which sounds way out of reach for the two of you.How do I buy a foreclosed home?
Not true! You will need to get a down payment as for any other property. If you qualify, an FHA loan requires the smallest down payment but I would advise you not to over stretch yourselves buying a house as this is precisely how people got into trouble and lost their homes. If you do not have any money saved, you should not be looking to buy anywhere.
