金融百科Investopedia给出的英文释义如下：

The term like-kind property refers to two real estate assets of a similar nature regardless of grade or quality that can be exchanged without incurring any tax liability. The Internal Revenue Code (IRC) defines a like-kind property as any held for investment, trade, or business purposes under Section 1031, making them a 1031 exchange. This means both properties involved in the exchange must be for business or investment purposes. Personal residences, therefore, do not qualify as like-kind properties.

（参考译文：术语like-kind property指的是两个性质相似的房地产资产，无论其等级或质量如何，都可以交换而不产生任何税务责任。美国内部税收法典（IRC）根据第1031节定义同类财产为任何持有的投资、贸易或业务用途的财产，使其成为1031交换。这意味着交换中涉及的两个财产必须用于业务或投资目的。因此，个人住宅不符合同类财产的资格。）

"Like-Kind Property"，在某些文献中也被称为"Like-Kind Exchange"，在美国税法中指的是两种或多种相似性质、用途或性质的不动产。当这些性质相似的不动产被交换时，根据IRC Section 1031（美国内部税收法典的第1031节），交换的所得可能会延迟或完全免税。

简而言之，"Like-Kind Property" 规定允许投资者交换某种资产（如房地产）以获得相似的资产，而不必支付资本收益税。

中文中，"Like-Kind Property" 可以翻译为“同类财产”或“相似性质的财产”。如：

In U.S. tax law, when you exchange one investment property for another like-kind property through a 1031 exchange, you can defer the payment of capital gains tax.

在美国税法中，当你通过1031交换将一个投资物业换为另一个同类财产（Like-Kind Property），你可以推迟资本利得税的缴纳。

You can't consider a personal residence as a like-kind property to do an exchange for tax avoidance.

你不能将个人住宅视为同类财产来进行交换以避税。

Even though two pieces of land might differ in location and size, they can both be viewed as like-kind properties.

尽管两块地的位置和大小可能有所不同，但它们都可以被视为同类财产。
