The ASP interest subsidy loan is eligible for a state guarantee free of charge. The state guarantee may be up to 25 per cent of the loan sum. You must agree on the guarantee in writing during the loan negotiations before you close the sale on your home. The bank and the customer may agree on the securities for interim financing. You can apply for a state guarantee (but only up to 20 per cent of the loan) as security for the interim financing, if necessary. In this event, a 2.5 per cent guarantee fee is paid for the guarantee sum, which is not returned once the interim financing is later replaced with the ASP loan. The guarantee fee is not returned if the deal is closed on or later than 1 January 2017.
