If you are thinking of co-buying a house with a friend you are among 13% of current home purchasers in the US. Co-buying is simply buying a house with another person, where both people become owners and are financially responsible for the home. This includes in most cases both buyers qualifying for the loan and not just someone co-signing for someone else to buy a house.
Co-owning a house with a friend can be rewarding both financially and also create complexities in a relationship between people. It is important before two people decide to buy a house together to understand the complete ramifications of what buying a house or condo will mean and that they have a set of rules to follow for co-living.
