As arule, the GOVERNMENT does not foreclose on properties;
the LENDER does.
The Government may INSURE the loan, but the Government stays out of the Foreclosure process.
After the house had been foreclosed, the Bank will LIST the property with a Realtor, and you may make an offer on it.
The Banks want you to have representation, they even pay for it,
So, contact a Buyer's Agent to help you.
