How to replace stairs?

[Wisteria]

In the old House Flipper, you could sell stairs and easily replace them with new stairs. In HF 2, I bought a house to flip, but there seems to be no way to change out the stairs. I've tried selling them, demolishing them, and placing new stairs over the old stairs, but nothing is working. Any advice?

You can't the devs said "Nah we know how much fun you liked in the first so we ain't going to add that stuff in this game. Actually we'll charge you about $50 to include all the stuff you want though."

You can use the flipper tool (sell tool), push R to switch to change style. You can't sell existing stairs but you can change the rail style, handrail placement, and textures/colors.

I think this should be a bit more obvious. I spent an embarrassing amount of time trying to figure out how to change the style of the stairs and I couldn't figure it out until friedchicken here wrote this.
