Best for a seamless online application

Bankrate’s view

Caribou lets borrowers compare refinancing loans on its lending platform. It matches borrowers with lenders like credit unions and community banks, which may help you score a competitive APR. The range of possible matches may even help you if you need to refinance with bad credit.

Many lenders offer online applications, but Caribou’s application process lets you apply, view offers and submit documentation in one place. It also encourages borrowers to bundle gap protection and other add-ons when signing off on a new loan. While this ease is a plus, it only stands out against competitors if you are in the market for one of these products — and don’t mind paying interest on their cost.

Best for large lending network

Bankrate’s view

Like Caribou, RateGenius is a loan marketplace that allows borrowers to compare many loan options simultaneously. Its network includes more than 150 lenders and uses your credit to determine the best option for refinancing. And in addition to refinancing loans, RateGenius’s network of lenders also offer lease buyouts.

Once you submit information about yourself and your current loan, you will be presented with offers. Some lenders offer the ability to prequalify, but it may not be guaranteed. RateGenius also has more stringent vehicle requirements than Caribou, although you can qualify even if you need to borrow less.

How to choose between Caribou and RateGenius

Both Caribou and RateGenius are solid starting points on your journey to refinance. They offer the ability for side-by-side comparison without harming your credit as well as relatively low starting rates.

Choose Caribou for prequalifying

The prequalification process gives you an idea of your expected monthly payment without a hard credit pull. Once you prequalify, you can factor that number into your monthly budget to ensure you can afford the loan — and that it is lower than your current auto loan payment.

Caribou advertises a minimum APR of 5.95 percent and a maximum of 28.55 percent. This minimum falls below industry averages based on Bankrate data. However, the minimum rate is likely only available to borrowers with excellent credit.

Another aspect to look out for is the potential $499 processing fee. While Caribou won’t charge you directly, the lender you’re matched with may pass it on to you. If you choose to go ahead with a Caribou loan, account for this additional cost in your budget.

Choose RateGenius if you need fast funding

Some people refinance because they are worried about missing an upcoming car payment and need to reduce their monthly cost. If this is you, you’ll want a fast refinancing process. RateGenius has funding available in as little as 24 to 48 hours. This is faster than many lenders and better than Caribou’s undisclosed timeline.

RateGenius’s online application is relatively simple, and many lenders allow for online document review, further expediting the process. And unlike Caribou, RateGenius works with lenders in all 50 states.

Compare more lenders before applying

Both Caribou and RateGenius give you the ability to compare several auto loan refinancing options. Caribou is an excellent fit for those interested in prequalifying, while RateGenius is better if you want a quick process.

Like any aspect of your finances, the key to securing the best refinancing loan is to compare lenders. Caribou and RateGenius make it easier, but you can always do the work yourself if you want to avoid the middleman.
