Hello! I wish to purchase an HDB apartment flat, but it has 2 and 5 in the house number. I have read from Feng Shui books that 2 and 5 together are considered very unlucky. Is this only true if 2 and 5 are together, in the case of #06-255? Or does this hold true even if 2 and 5 are separated by other numbers or a dash (e.g. #05-246 or #10-285)? Thank you!
