Why 13-14 is acceptable ?
13 - a unlucky no in Western belief.
14 - a unlucky no in Cantonese pronounciation.

No number 4 but 14 is acceptable? Hehe.

I prefer Number 4 than 14 then. I dislike No 13,13A and 14.

But, i accept the house or unit number. Not floor or level bcz I found most ppl do not mind the numbering of Unit 3A but the floor of 3A and 13A. 23A is so-so but better than both.

The problem is that you don't get the 1314 in full, you only get the 13 and 14 separately.

Even if you get 1314 in full it is not neccessarily good. It could 1314 happiness or 1314 working as slave.

Look like your intepretation is too 一廂情愿！If you are buying for own stay, your own intepretation is good enough for you. You don't need to bother with others. But if you intend to sell it later, then your own intepretation is not going to be much meaning.
