What should I do with these wooden floors?

[Benjamin Furney]

Hello Biggerpocket Folks!

I am going to be putting luxury vinyl planking in the entire downstairs (kitchen, living room, etc.) However, what can I do with these stairs? I dont think the wood can be salvaged, nor will it match with the floor?

Should I paint the backdrop white and put vinyl planking, or will this cost too much money? I heard vinyl planking on stairs is very expensive.

Should I do carpet?

Thanks everyone!
