Does anyone have experience with DSCR lenders?

[Sylvie Kuzminski]

I have used Launch Financial (NOT A DIRECT LENDER) (I posted my thoughts on these guys here if anyone is curious). The DSCR lenders who wrote the actual loans are Lima One and Deephaven Mortgage. I do not want to continue with Launch as a middleman, but when contacting these lenders directly, they won't work with me- I get referred back to Launch.

Anyone have any experience with DSCR lenders themselves? Would be great to get some feedback!
