A quick sale is what every seller is looking for. The goal is to not have the property on the market for a long time but sell it as quickly as possible. In order to achieve this you have to take in consideration the fact that the majority of the potential buyers are looking for a home that doesn't require any immediate work. They might be planning to make changes later, but the house needs to be adequate for living.
That is the why you need to thoroughly prepare your house for selling. The first thing to do should be to make a list with every room and all the items they contain that you no longer want or need, like pieces of furniture, electrical equipments, paintings and so on. You should also make a list with every task that needs to be done including functional repairs like dripping faucets, sticking doors, broken fences, walls that need painting, loose locks that needs to be changed etc.
