Hardly seems worth it. You can get a well equipped Grand Cherokee with an MSRP well over $40k in the upper end of your range.
What you are basically telling me is if you plan to lease, the Renegade is NOT a good vehicle choice.
Just a FYI, but when I was shopping for my X1, I also looked at the Subaru XV Crosstrek, and I was quoted no money down, $315/month for the same term and mileage, and that was for a fully loaded Crosstrek Limited with all available options, MSRP around $27k. A fully loaded Jeep Patriot with an MSRP around $28k was around $330/month as well.
Perhaps it's just too early and there are no incentives yet on the Renegade. I suggest waiting a few months. Every other Jeep in the lineup has lease incentives, even the Wrangler. There will be Renegade incentives too once they catch up on demand and some start to sit on dealer lots.
