government-backed loan → δάνειο με κρατική εγγύηση
A government-backed loan is a loan subsidized by the government, also known as a Federal Direct Loan, which protects lenders against defaults on payments, thus making it a lot easier for lenders to offer potential borrowers lower interest rates. Its primary aim is to make home ownership affordable to lower income households and first-time buyers.
