I refused to buy a property in the past because it was no.13. Not really because I was particularly superstitious but because I was worried that if we wanted to rent or resell in the future we might alienate part of any potential market.
I have worked for builders in the past in housing and apartment complexes and we would just skip the number 13, so the houses went 10, 11, 12, 14 and so on. In some estates you can find 10, 11, 12, 12A, 14 etc..
