One other thing I forgot to add. Start remodeling project. Preferably of the kitchen. If you can afford it tear up the kitchen enough that it is impossible to do anything. We actually had our refrigerator in the dinning room and the stove disconnected. The wife and I were going out or ordering in for several months and it took serious commitment to slow the project down enough that we finally got a firm move out date from one of them. The step before a remodel is to cut off the free food train.... We started only buying food we liked or that we had time to make ourselves and no leftovers. Only cook enough for you and the spouse and be sure to finish your meal before they arrive home for the evening that way you don't have to feel guilty about eating in front of them. Discontinue buying snacks or quick easy things like sandwich food. If they start buying ramen to eat and cook it in the microwave put the microwave in storage or get rid of it. It is very important to cut off the gravy train and the whole time you are going through the steps to get a child free house ask them on a regular basis what their plans are for the future. Help them set some goals and be sure to bring it up often enough that it starts to annoy them. Most importantly start charging them rent, this is your very first step to freedom. Start off low, just enough to cover one of the bills they are incurring at your house, let them know that it will be increasing in x amount of time. Steadily increase the rent until they notice. In our case we were first saving the money to help them move out but after a year we gave up and decided to go and buy each other or the house something noticeable and made sure to do it right after they paid rent so they would see where their money was going.
