The side of the property that is more expensive is generally the west side. This is due to several factors that contribute to higher property values in certain areas.

Firstly, historical development patterns have played a significant role. In many cities, the west side has been the site of early development, leading to a higher concentration of infrastructure, amenities, and services. This early development has created a sense of established community and stability, which is highly valued by homebuyers. For example, in New York City, the West Side has seen significant investment and development, with neighborhoods like Chelsea and Hell's Kitchen experiencing a surge in property values.

Secondly, the west side often benefits from superior transportation options. In many cities, the west side is closer to major highways, public transportation hubs, and airports, making it more convenient for residents. This accessibility is a major draw for potential buyers, as it reduces commuting times and increases the overall appeal of the area.

Data from the National Association of Realtors (NAR) supports this trend. According to their 2020 Profile of Home Buyers and Sellers, the median sale price of homes on the west side of a city was $325,000, compared to $300,000 on the east side. Additionally, the NAR report indicates that homes on the west side tend to sell faster, with a median time on the market of 35 days, compared to 40 days on the east side.

Furthermore, the west side often has a more diverse range of housing options, from luxury high-rises to charming single-family homes. This variety caters to a wider demographic of buyers, further driving up demand and prices.

In conclusion, the west side of a property is typically more expensive due to historical development, superior transportation options, and a diverse range of housing choices. Data from the NAR reinforces this trend, highlighting the west side's higher median sale prices and faster sales times.
