Room #210 climbs from BEAD to FORM. Of their 4 letters, 4 differ (positions 1, 2, 3, 4); each of those needs a rung of its own, so the shortest imaginable ladder has 4 rungs — par here is 5.
So 1 rung is a sidestep: somewhere a correct letter gets spoiled for a moment, or a letter from neither word is borrowed.
If a step leads to a word that can only change back, undo it and try another position.
Four-letter words, but five or six steps.

Hint: the first step
Change letter 1 to R: READ.
