You don’t have to be married to someone to buy a house together; however, some important factors should be considered before signing the papers. Both parties must have qualifying credit scores and income to be approved for the mortgage loan. You also need to decide how you want the property to be vested, or how you want to hold title jointly. In addition to these basic considerations, you should think about creating a legal agreement in case the relationship goes sour and the house needs to be sold. This is because no solid laws or regulations exist concerning joint property owned by people who aren’t married to each other.
