No you do not need a license. There are DIFFERENT types of foreclosures: sheriff sales (real foreclosures), short sales, and REO (real estate owned). For instance, a "true forclosure" is a sheriff sale auction and you will not have an agent or realtor, you better know what you are doing, you are buying "as is", need to understand title and lien issues, AND you need to be able to buy in CASH. And that's just the tip of the iceberg.
Unless we know what type of foreclosure that house is, we can't possibly start to suggest the proper next steps. And yes - it's too much trouble to list them all out. Sorry about that but foreclosures are a big subject.
Would you please provide some more info?
