This is the 6 I use

Can Capital-A paper
GBR-they have the greatest pre-approvals but decline a lot later on in underwriting
SFS-very reliable and an amazing system for syndication
Snap-very diverse for your 6 month and up paper, they fund in Canada and PR
Retail Capital-outside of the box
Yellowstone-they will fund almost all of my highrisk and decline paper, lower commission but very important to get these type of deals funded
