I doubt they will allow a higher deductible if they specify a certain deductible amount. It wouldn't be fair to other customer's of NFCU to allow you a different deductible amount than everyone else. Definately be cautious of this, once you end up buying a vehicle, insure that you are within the insurance deductible requirements of your lender, otherwise they will put costly force-place insurance on the vehicle.
There is alot of research that goes into their required deductible amounts, lender's typically prefer a lower deductible because it insures that their property (the collatoral) is better taken care of, in that customer's can afford to fix the vehicle in the event of needing to file an insurance claim.
And, like I said, if NFCU found out that person has a higher deductible than allowed, they reserve the right to put force place insurance on the collateral which is ungodly expensive.
While the information I provided may not be "beneficial" to you, it may be beneficial for someone else to know why lender's require "$xxx" for a deductible and no higher.
I am approved through NFCU but all the paperwork says $500 deductible. Do you think if I call them I can ask for $1000 instead?
Absolutely, do this. Then update please.
