As a legal expert, I can provide insights on JD Tower, a new and upcoming development in Egypt's New Administrative Capital (NAC). JD Tower is a mixed-use development that boasts both residential and commercial spaces, and is set to become a prominent landmark in the NAC.

Firstly, it is important to understand that any construction projects in Egypt, including JD Tower, are subject to certain laws and regulations. This includes obtaining the necessary permits and approvals from the local municipality, as well as ensuring that the project adheres to safety and environmental standards.

When it comes to purchasing a residential unit in JD Tower, potential buyers should review the property documents carefully. This includes scrutinizing the title deed, which confirms ownership of the property, as well as any contracts or agreements related to the sale. It is also important to conduct due diligence on the developer and ensure that they have a solid track record and reputation in the industry.

Furthermore, potential buyers should also consider their financing options, as well as any taxes and fees that may apply to the transaction. This includes researching any mortgage or financing options that may be available, and understanding the tax implications of purchasing property in Egypt.

It should also be noted that JD Tower is located in the New Administrative Capital, a new city that is currently under development. As such, potential buyers should be aware of the potential for changes in the surrounding infrastructure and development, as well as any future plans or projects that may impact the property's value.

Overall, JD Tower is a promising development that presents a unique investment opportunity in the NAC. However, it is important to approach the purchase of a residential unit in JD Tower with caution and care, and to seek legal guidance throughout the process.
