OP, I'm not sure if you were asking about specifics, but I applied with about 4 different personal loan providers in the same day. This probably only helps people who are in the U.S. because most of these providers require a U.S. address. I applied for >$50k, with approximately a 4 year term. From best rate to worst rate according to interest rate/APR:
1. SoFi. They offered 8%
2. LightStream (Suntrust). They offered 9%
3. Wells Fargo. They offered 11%
4. Prosper. They charged an expensive (maybe 2%?) origination fee and only issue loans up to $50k, so I didn't even bother.
I went with LightStream because I didn't know the APR of SoFi. SoFi wouldn't tell me the rate unless I gave them my bank information to automatically deposit the funds. I wasn't about to automatically agree to the loan without them telling me the APR! On the other hand, the process with LightStream was great and they were very upfront/honest about everything. It wasn't until after I took LightStream and the SoFi loan expired that I found out the APR on the SoFi loan. That is frustrating, but oh well. I suppose I can always refinance after a couple years. Something else to know is that LightStream will beat any other offer by .01% APR if you do a "Rate Beat" PRIOR to funding the loan.
From what I've read, you need a high credit score for SoFi and LightStream. They weigh your credit score more than other factors, but you'll definitely need proof of a good enough income.
Hope this helps!
