Overall
Rent vs. lease
Both leases and rentals allow one party, the lessee / rentee, to use an asset owned or controlled by another party, the lessor / rentor. The difference, lease agreements cover a long period of time, while rental agreements do not.
For example, a lessor may lease a building from its owner and sublease individual units to sub-lessees.
As far as the guidance is concerned, no difference between rent and lease exists.
