I went with EDvestinU primarily for the low interest rate—it was one of the most competitive I had ever seen and I couldn't pass it up. The account manager at my previous loan servicer tried to get me to stay but knew they couldn't match what EDvestinU was offering.
For the application process I was surprised that two personal references (not to be confused with co-signers) were required, I have never seen that before on a refinance application. Both references though were never contacted, my guess is that their contact info is stored in case I skip town and need to be located (I don't plan on doing this by the way).
This was not my first student loan refinance, so I knew the process going into it and the different documents that were required. EDvestinU does a good job notifying you what documents still are needed to complete the process. My only complaint was the time the disbursement took, I wish there had been a little more communication to update me on those steps. However when I called in I spoke with Emily and she was able to very quickly look into it and let me know the expected timing for it, along with a few other questions I had. It was great customer service.
The online servicer platform looks to be user friendly, I was able to easily register, have an overview of my loan details, and set up autopay.
I definitely recommend EDvestinU.
