Becoming a minimalist may not be for you, but you may want to become one if you need to sell your home.
When people are looking to purchase a home, they are looking for a home large enough for their needs. They want to come into a home and visualize where all their belongings will go. This becomes difficult with your stuff in the way.
Decluttering goes way beyond dusting. If you are moving out anyway, go ahead and put your stuff in boxes and get them out of the way. Take the decorations off of the walls and out of the windows. People want to see the openness of the room and see how their decorations will go well with the house.
Pictures of grandma should go. Walls should only have 1 picture on them at most. Clean out the closet because they will be looking in there. Get rid of anything that collects dust like plastic plants. Remove throw blankets and pillows. Put away or box up all of those knick knacks.
You may choose to remove as much as half of your belongings, but on the bright side, they will already be boxed up and ready to move when your home sells!
Once you have your home open and free of clutter, you have greatly increased the odds of selling your home fast!
