The majority of providers offer e-mortgages of up to a maximum of 95% of the value of the property, or its purchase price, whichever is lower. Therefore you will need to save up a deposit of at least 5% of the price. 100% loans are available but you they are more expensive, in terms of the interest charged. Although you automatically pay more by borrowing the full amount, many financiers charge you additional interest on 100% loans. Another major cost to take into account is the mortgage indemnity guarantee (MIG) premium. This fee covers the broker for the added risk of advancing larger loans. It is usually activated when the loan is for more than 75% of the property's value and rises with the amount you borrow. On loans over 95% it is usually quite high.
