We lease sales centers, office space and equipment under operating leases. Our leases expire at various dates from 2020 through 2030, with varying renewal and termination options. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

We recognize rent expense on leases with both contingent and non-contingent lease payment terms. Rent expense associated with non-contingent lease payments are recognized on a straight-line basis over the lease term. Rent expense for all operating leases for the year ended December 31, 2019, 2018 and 2017 was as follows:
