What is the primary difference between a gross lease and a net lease in commercial real estate?

Option B: In a gross lease, the landlord pays all expenses, while in a net lease, the tenant pays all expenses including mortgage payments

Option B is incorrect because it overstates the tenant's obligations in a net lease. While tenants in net leases do pay operating expenses, they never pay the landlord's mortgage payments, which remain the owner's responsibility. Mortgage payments are financing costs, not operating expenses. Additionally, the statement about gross leases is incomplete - landlords pay operating expenses but tenants still pay rent. The distinction isn't about who pays 'all expenses' but specifically about operating expense allocation.

Option C: In a gross lease, rent is paid monthly, while in a net lease, rent is paid quarterly

Option C is incorrect because payment frequency (monthly vs. quarterly) is not what distinguishes gross from net leases. Both lease types can have various payment schedules depending on the negotiated terms. The fundamental difference lies in expense allocation, not payment timing. Commercial leases in Canada typically specify payment frequency in the lease agreement regardless of whether it's structured as gross or net.

Option D: In a gross lease, the lease term is shorter, while in a net lease, the lease term is longer

Option D is incorrect because lease term length is not the distinguishing factor between gross and net leases. Both gross and net leases can have short or long terms depending on the specific agreement between parties. The lease term is negotiated based on tenant needs, market conditions, and property type, not the expense allocation structure. The fundamental difference relates to who pays operating expenses, not lease duration.
