Multi-family and apartment funding purchase

I would say I'm fairly still a newbie investor. Its just been little over a year and I have managed to acquire 4 units (2 SFH and a Duplex). I think I'm also seasoned enough to take the leap of faith and embark upon my next acquisition which is an apartment complex with 25++ units. I have done extensive research, reading and podcast viewing by biggerpockets among others etc as it relates to gearing before, during and after acquiring one. I have a few silent partners/investors who are willing to put in on the deal for down payment for a decent % return. My questions is has anyone used Sofi for a major purchase besides hard money lender/institution or conventional bank? I am seeing sofi offering loans up to 3M with as little as 10% down and options of interest only loans.
