i am looking for a short lease but i have poor credit. can get approved if i pay the lease in full?

No. Even with a "one pay" lease, you still must qualify just the same as with a standard lease. If your credit is not strong enough for that, you won't get approved. You're a very high risk and no one will take a chance in today's market.

Yes, you're paying the entire lease up front but your credit says you are not a responsible person. And since cars are on 4 wheels and can easily be driven out of state or hidden, that is a risk no lender will take. Sorry.

Generally, you must have good credit to lease. However, some lease companies relax the rules a little if you take over someone else's lease for a short term. Here's more about it:

It takes better credit to lease a car than it does to buy one. With a 493 credit score, you don't have many options.
