Open houses are a great way to look for homes but can be time consuming. Why not do some research before you hop in the car? Most Realtors post their open houses on the MLS. They will be listed by date and neighbourhood. Reviewing these will assist you in preparing a list of homes in the neighbourhoods you like as well as planning your tour in such a way that you’re not using up an inordinate amount of gas going from one home to the next.
