That just seems like a big task to accomplish. But I’ve done that for several people, help them upsize and sell their smaller home.
And I’ve actually done it for myself and my husband in the last 5 years. We just decided we needed a bigger home. We now had 2 kids and 3 dogs and we needed home offices — so we decided to upsize. In our case, we bought first, and then sold our house… but that doesn’t work for everyone. It’s something you need to explore with your (real-estate) agent.
