First of all, geographical location is an important factor affecting housing prices. Liangxiang Guanrong Community is located in Fangshan District, Beijing. Compared with the core area of Beijing, the economic development and infrastructure construction in this area may be relatively backward, so the house price is relatively low.

Secondly, the supporting facilities and services of the community may be relatively few. Some high-priced houses often provide high-quality supporting facilities and services in the community, such as swimming pools, gyms and gardens. Cheap houses may often lack these facilities and services, so the price is relatively low.

In addition, housing quality and design are also important factors affecting housing prices. Some high-priced houses often pay attention to the quality and design of houses and provide high-quality decoration and materials. And some cheap houses may use simpler decoration and materials, which reduces the house price.

Finally, the relationship between market supply and demand will also have an impact on housing prices. If there is too much housing supply and less demand in this area, house prices may be lower.

It should be noted that the above are only possible reasons, and the specific situation requires comprehensive consideration of relevant factors before making a judgment. These factors may interact, so I can't accurately understand the specific situation of Guanrong Community in Liangxiang, so the above speculation is for reference only. If you have specific questions, I suggest you consult relevant professionals.
