How Soon Can I Take Out a Home Equity Loan or Refinance After a Cash Purchase of a Foreclosure?

The house is only 10k. So if I pay 10k cash, how fast can I do a home equity loan for that 10k? I need to make repairs as it is a foreclosure in poor condition. Can I do a refinance loan and get more than I even paid for it if it appraises higher than 10k, which it will? Thanks for any help
