Yes, to both. The 4.2% annual interest rate is used to amortize the lease in much the same way that a loan is amortized. The Adjusted lease balance is comparable to its loan balance cousin and is easy to calculate. To find the interest rate, use the Excel RATE function which I’ve detailed in several other posts.
Honestly, I would be very reluctant to lease in Ill and NY because of taxes, especially if I’m going to purchase the vehicle within 30 days.
If you carry the lease to full term, you will owe the residual value which is shown in Section 11 in the amount of 26,833 plus tax and any applicable fees. If you buy the vehicle, you will pay the agreed upon value (sell price) of 50113 plus tax and other fees. However, there may be other discounts available only to purchasers which means your purchase price may be considerably less than 50133. This is something you should address with the dealer. I would also check Edmunds to see if there are other rebates/incentives. Buying within a month will probably cost about 51,300.
Not sure where you’re getting 4461. You may want to check out my post dealing with the lease v, buy decision…

Of course, your payments will be higher. You need to look at the 24 v. 36-month lease and analyze the initial cash layout differential, payment differential and lease balances at the end of 24 months. It’s similar to a lease v. purchase analysis. I can’t give you an answer without doing an incremental cost analysis and that does take time to do. Usually, it boils down to one’s own preferences and so, there are intangibles to consider that factor into the decision.
