Hi, I’m Alice from Westpac and I’m a home loan expert. Buyer beware. There are costs when buying a home that you might not have thought about. Here are some of the common expenses overlooked. The first one is Stamp duty. Stamp duty is a general tax imposed on certain purchases, such as property. Stamp duty varies state to state and by the value of the home purchased. Another commonly overlooked fee is that you may need a Solicitor. There are a number of legal steps to transferring a property from one party to another.
