用“Lessor”和“Lessee”也可以，但“Landlord”和“Tenant”更为合适，因为“Lessor”和“Lessee”是比较宽泛的表达，而“Landlord”和“Tenant”更适用于房产租赁这一语境。

“Lessor”和“Lessee”常见于对某一资产的出租。Lessor and Lessee are two parties to a lease agreement. An agreement or a contract by which the owner (lessor) of a specified asset grants permission to another party (lessee) to use the asset for a specific period of time and with defined terms and conditions in return of periodic rentals, is termed as a lease.

“资产”的范围涵盖很广，如下文飞机租赁协议中的出租人和承租人即可用“Lessor”和“Lessee”：

We refer to the amended and restated aircraft lease agreement dated January 28, 2019 between AAA Company Limited (the “Lessor”) and BBB Limited (the “Lessee”) relating to one (1) Airbus A350-941 aircraft manufacturer’s serial number 246, together with the two (2) Rolls-Royce Plc model TRENT XWB-84 Engines specified in paragraph 3(b) (the “Aircraft”) (the “Lease”).

此处涉及AAA有限责任公司（“出租人”）和BBB有限公司（“承租人”）于2019年1月28日就一（1）架制造商序列号为246的空客A350-941型飞机及第3(b)条所载劳斯莱斯公司制造的两（2）个TRENTXWB-84引擎（“飞机”）签订的经修订和重述的飞机租赁协议。

“Landlord”和“Tenant”只适用于房屋租赁协议中的“出租人”和“承租人”。在某些语境，特别是工程承包中，“Landlord”还多译为“业主”。“出租人”和“承租人”是各国的民法中比“房东“这一概念更正式、更中性的法律用词。

且与“Lessor”和“Lessee”相比，“Landlord”和“Tenant”更一目了然。前者发音像绕口令，“形象”如双胞胎，非常容易混淆。类似的“renter”也是。

以下为相关双语示例，供参考：

根据《中华人民共和国合同法》等有关法律规定，甲乙双方就商铺租赁事宜，均已审查对方签订本协议的主体资格。甲方作为本协议的出租方，乙方作为本协议的承租方，经双方自愿、平等、协商一致，达成协议如下：
