Room #102 climbs from SOLD to WIRE. 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 4.
Par equals the number of different letters, so every step can put one letter of WIRE in place. The puzzle is only about the order.
Try changing the vowel first; short words tolerate vowel swaps well.
Four-letter words and short ladders of three or four steps.
