If you want to sell your house, aside from the washing and the scrubbing, you need to remove the clutter. This doesn't only mean taking taking out the obvious trash like, empty cans of paint or boxes of unused items that have been sitting in the garage for as long as you could remember. It also means removing personal items from the house. To you, these things are special and looks part of the house. But to potential buyers, they are clutter.
When you show your house to buyers, they need to be able to visualize themselves living in it. But they can't do this if there are too many personal things like souvenir items from your vacations or events, personalized wall decors and pictures. Instead of making them feel like this house could be theirs, it will make them feel like they're intruders.
No matter how clean your house is, if there are many things, it will look crowded and it will be unappealing to buyers. I know, these things are important and special to you, so removing them from where they've always been will be heartbreaking. But you don't have to get rid of them, you just need to move them away from the house you'll eventually part with too. Consider renting a warehouse where you could still keep them.
You need to clear the house from clutter but it doesn't have to be empty. Just aim to make the house look neutral.
Classify your things according to things you're going to keep, donate and throw away. It might actually be high time for you to go over your stuff - especially those you haven't even seen for years and say goodbye to them for good. You can think about selling some of your things in a yard sale or online but it will take time and effort - two things you usually don't have enough of when you're in the process of selling your home. If however you are intent on selling some of them at a later time, eBay and Craigslist are the most popular sites to turn to. But you'd be doing yourself and a lot of people a big favor if you just give away as much as you can.
