Sale-leaseback is a very particular form of a financial instrument where one party (the seller/future lessee) that owns an asset sells the asset to the second party (the investor/future lessor). Then, the seller leases the asset back from the buyer, therefore the seller becomes the tenant, and the investor is the landlord.
Benefits for the seller/future lessee include leveraging their real estate assets to raising capital instead of taking out a high-interest loan from the bank. Furthermore, they are selling the asset at the current market rate, which is likely to be higher than its initial purchase cost. Entering a lease with a new landlord also gives them a chance re-negotiate any terms they wish.
John Campbell, Manager, Industrial Services, Savills Vietnam commneted “Benefits for the investor/future landlord include acquiring an operating asset that produces an instant return on investment in the form of monthly rental payments. Therefore, ‘built-in tenancy’ ensures they do not need to spend cash on leasing or marketing campaigns to source potential tenants. Predicable and secure cash flow and a satisfactory yield over a relatively long lease term (usually 10 years) provide comfort for the investor/new landlord.”
