If we sell our house and move to a bigger house as primary home,will it lower our EFC

<p>$400k, even an $800k home is just a condo in some area. I use it as an example anyway.
I just wonder why some people move to a bigger house when their kids go to colleges. It should be downsize because of more expenses and less people in the home. As someone said, the profits of selling house will be treated as income, thus impact EFC a lot. It seems staying the seam house is a good idea. I confused.</p>
