Hi gtechnc,
In feng shui there is no superstition in numbers. Yes for Chinese the no. 14 sound pretty bad as it sound like “sure die” in Cantonese dialect. However if your Kua no is either 6 or 7 then 14 can also be your lucky no.
Overall it is important to have a good external and internal landform because in feng shui we talk about qi and not superstition numbers. I have an old neighbor who live in house no.4 but 5 years later he became a multi-millionaire.
You must also consider that the property price of such houses will fetch slightly lower if you are staying in a Chinese populated country.
