Can a lay person become an Arahant according to the Suttas? I have already seen different answers to that question, but I don't know which one is based on the suttas. I would appreciate the source of the answer for this specific topic. 

If you think the answer is "No", could you please write about how far a lay person can get? Just a higher rebirth?
The answer is Yes. Please look through this website. 


  "If a layman attains arahant-ship, only two destinations await him; either he must enter the Order that very day or else he must attain parinibbàna" -- Milindapanha III.19
