Question to the group, Are these MDF steps OK? any known problems, should
they be sealed with something?

Its a fairly standard material to use for them these days. Its
dimensionally stable and hence does not tend to cup and twist like
planks can. Hence it stays quieter. Under carpet it would be fine. No
need to seal with anything in particular, but there is nothing stopping
you giving it a coat of quick drying varnish if you want.

Since you specified real wood, I would either ask for a small discount
(say 10-20%) or use it as a bargaining chip later when you want
something from the builder.
