2018 Dodge Durango GT Lease

I’m new to the forum. I am negotiating a lease with a dealer in Long Island NY.
2018 Durango GT with the Rallye package, premium group, and captains chairs.
MSRP: 46,925.
I owe one payment of $425 on my current lease (Grand Cherokee Overland) and a $395 Disposition since im with US bank and would not be using TFCU (Teacher’s Federal Credit Union).
The dealer said they would cut me a check for $875 to pay my last month and the disposition fee.
The deal for the car is $900 down (including first month) and $490 per month for 39 months and 10k miles per year. I do not have a selling price of the car I am waiting on the dealer to get back to me. In the meantime, the dealer told me the Money factor is .00035 and the residual is 53%. Can someone verify if these are correct?

Also, I see that there are 3,500 in incentives for August, can someone also please verify. I will give you guys the sale price once I speak to the dealer again later today.

Thank you in advance!

Ok so I got some more info.
Sale price - $43726
Rebates - $7,0000
Price after rebates - $36726
The car will be leased and registered in NY.
If anyone can get me some numbers on what my payment should look like that would be awesome.

Thank you in advance!

Some more info, the cap cost is $40809.

$3,199 dealer discount is only 6.8% off MSRP before rebates. Go here to enter your zip code and pick your trim level for incentives and rebates - https://www.autobytel.com/dodge/durango/2018/incentives/

Ask the dealer to confirm the rebates/incentives that are being applied - you want to be sure that they haven’t added any that don’t apply to you.

Also, be sure they itemize how they get to the price after rebates ($36,726) to the Adjusted Cap Cost ($40,809).
