The Impact of Noise on Property Value When it comes to buying a property, there are many factors to consider. Location, size, and amenities are often at the top of the list. However, one factor that is often overlooked but can have a significant impact on property value is noise levels. Noise can affect not only your quality of life but also the value of your investment. Research has shown that noise can have a significant impact on property value. Properties located in noisy areas, such as near busy roads or airports, tend to have lower values compared to properties in quieter areas. Noise pollution can affect the desirability of a property, making it less attractive to potential buyers. It can also impact the quality of life for residents, leading to higher levels of stress and reduced enjoyment of the property.
But by how much? Historical works indicate a decrease up to between 8 and 18% for a 10 dBA increase in noise level, but we feel that value can be misleading.
For example, If you have a very quiet property and the same property is even quieter, that's unlikely to result in a change in property value. Likewise, very noisy properties are also unlikely to vary greatly in value (all other things being equal) for roads, rail, and airports that are already in existence. We believe it's in that mid range of exposure, around those noise limits recommended for health, is where a noticeable shift in value is noted with changes in transport noise exposure. However, when a new road, rail line, or airport is introduced where no noise emitting sources are around, the drop in property value due to the increase in traffic noise can devasting, even after taking into account the potential increase in value due to access to the benefit of the asset being constructed.
Ambient are looking to complete a detailed study to further quantify the relationship between transport noise and property value in 2024.
In addition to affecting property value, noise can also have negative effects on health. Prolonged exposure to high levels of noise can lead to stress, sleep disturbances, and even hearing loss. It is important to consider the potential health impacts of noise when choosing a property. Living in a noisy area may not only affect your property value but also your overall well-being.
When considering noise levels in your property search, here are some tips to keep in mind:
- Research the area: Use the Ambient noise Summary or Detailed Noise Reports and other resources to understand the noise levels in the area you are considering.
- Visit the property at different times: Noise levels can vary throughout the day. Visit the property at different times to get a sense of the noise levels during peak hours and quieter times.
- Consider noise-reducing measures: If you find a property you love but it is located in a noisy area, consider what measures can be taken to reduce noise. This could include installing soundproof windows, building a solid fence, or adding insulation to walls.
- Consult with experts: If you are unsure about the impact of noise on a particular property, consult with experts such as real estate agents or noise consultants. They can provide valuable insights and help you make an informed decision.
