Despite our different views, understanding and speculations in John 14:2.
Perhaps if we humble ourselves and let the Lord Jesus to explain (through his words) the truth in John 14:2 will be revealed to us and we will have 1 understanding.
Because it is only Jesus who is revealing the truth.
MARK 4:34
34 But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples.
Then Apostle Paul mentioned that the truth he learned, no man on earth taught him but by Jesus Christ revelation alone.
GALATIANS 1:11-12
11 But I certify you, brethren, that the gospel which was preached of me is not after man.
12 For I neither received it of man, neither was I taught it, but by the revelation of Jesus Christ.
Since when Jesus revealed the truth to Paul, Jesus is already in heaven.
Thereofore if we humble ourselves like Paul, Jesus (from heaven) could also be revealed the truth in John 14:2 to us.
