Short answer: Same bank rates, but plus 1% annual lender premium to the government.
The interest rates are the same as normal home loans from the same bank. But you pay an extra 1% per year as a lender premium because the government is backing your small deposit. This premium goes to the government, not the bank. It is the cost of being able to buy with only 5% down.
