Getting rid of the clutter in your house is imperative when you are putting it up for sale. It will make the entire process more real for you, in addition to making a good impression on both your real estate agent and, more importantly, on potential buyers.
Once you have lived in a house for a while, you are bound to have a lot of clutter. Much of it has sentimental value and may be important to you. However, you have to admit, that quite a lot of it amounts to so much junk. Even before you start packing in earnest, you should begin separating the clutter from the junk. The former can be organized. It might be a good idea for you to finally throw the latter away once and for all. This is an excellent time to do it. If you have not used something in over a year, or even longer, then you probably do not need it anymore. You can either throw it away or donate it to someone or some organization which can use it.
As for the clutter, well, that can be anything. Packing up your books, your knick knacks, and the items cluttering the kitchen counters is another great way to begin depersonalizing your house. You can separate the essential items from those items which are not essential, and mark your boxes accordingly. You will be surprised at how much packing you can get done by doing this.
