To be able to get a lendingtree loan Lendingtree requires at least a 640 or higher credit score.
The higher your credit score the higher chance you have at getting the loan through Lendingtree and also you'll likely pay less interest on the lendingtree loan.
I tried for a lendingtree loan before when my credit score was only 600 and I didn't get approved but once my credit score got to 640 then I was able to be approved for the Lendingtree loan.
You might also be able to get a cosigner to sign for the lendingtree loan if you contact Lendingtree and if the cosigner has a 640 or above credit score you should be able to easily get the loan.
You can also raise your credit score by using a secured credit card such as the secured credit card through Capital One.
You put a deposit of around $200.00 or more up and that is your credit limit.
Then as you pay back the credit card on time you get that deposit back and your credit score increases.
