I bought my RAV4 Prime in Feb (Virginia dealer) and got the $6500 lease cash, and also a $750 military incentive (also paid $650 lease acquisition fee - no way to avoid it). I did not mention my plan to buyout early.
Lease money factor was really bad, even with excellent credit - equivalent to 8%.
Made one payment, sold my other car, and then asked TFS for the buyout package. Paid it off with a bank check and got the title. No additional surprise fees. No termination or disposition fees.
FYI - in Virginia there is no sales tax credit for your trade-in, so no savings if you trade in.
