This lease currently isn’t a good deal at all, but Tesla historically doesn’t offer favorable leases despite holding the best resale value in the industry.
By assuming a 60% residual, which is conservative on the Model 3, and applying the $3,750 tax credit as an incentive the lease would be much cheaper as verifiable by the Leasehackr Calculator.
Even without the tax credit the $41,200 Standard Range Plus model would be $382/month with $1,553 due at signing assuming a 60% residual. With the $3,750 tax credit applied as an incentive, that drops to $271/month.
Hopefully they can figure out a way to offer more competitive rates without negatively affecting cash flow.
