Has anyone used Rate.com?

[Eddie Starr]

I saw this site listed on BiggerPockets.com as a recommended lender for real estate investors.

I was also looking for other sites with information about Rate.com, 

and came across one review on: https://www.nerdwallet.com/best/mortgages/interest-only-mortgage-lenders

According to the above site, the minimum score requirement is 620, with 3% down. Is the 3% apply to I/O loans, and can they be used by investors?

I'd like to hear from investors who may have used them.
