Let's expand on this.
People assume that renting out property is rent-seeking literally only because they both have the word rent in them.
I would note that people don't use the word rent-seeker (or parasite) when it comes to banks renting out money. I assume this is partly because banks use the word `loan` and partly because referring to bankers as parasites would be a little too close to dog-whistle antisemitism.

It's not a coincidence that they have the same word in them. It's literally just the same word with the same definition and etymology in both cases. Rent is a payment demanded by property owners from people who want to make productive use of that property.
