Most lease payments are fully deductible as they're paid. Lower total cost. The lifetime cost of many things is considerably cheaper if you buy rather than lease. Once you've bought something, you don't have continuing monthly payments. You won't feel as stressed when you have a bad month.
Most leases are for a set time-period.
You can't easily get out of them. If you move, go out of business, or undergo other changes, you still have payments. If you own your own equipment, furniture or vehicles, you can take them with you, or sell or donate them. You've got an asset instead of a liability. Once you've bought something, it's on your books as an asset of the business, which increased your company's value.
