Juli Park Huafu and Hailiang Riverside No.1 are two different buildings, and their price difference may be due to the following reasons:

1. Location factor: Juli Park Huafu may have a superior location, such as being in the city center or near the business district. Hailiang Binhe No.1 may be located in a relatively remote area, so the price is relatively low.

2. Developer brand factor: If the developer of Juli Park Washington is a well-known and reputable brand, its price may be relatively high. The developer of Hailiang Binhe No.1 may be relatively ordinary, so the price is lower.

3. Property supporting facilities: Juli Park Washington may provide more high-end supporting facilities, such as swimming pools, gyms, business centers, etc., while the supporting facilities of Hailiang Riverside No.1 may be simpler, so the price is lower.

It should be noted that the above are only some possible reasons, and there may be other factors that cause the price difference, such as building quality, apartment design and surrounding environment. If you want to know the specific reasons, it is recommended to consult the sales staff of the relevant real estate or consult the relevant market report.
