Deephaven Mortgage is accelerating its push in debt-service coverage ratio (DSCR) lending, rolling out a new API integration with Lightning Docs aimed at removing one of the biggest bottlenecks in business-purpose lending: document generation.
The integration connects Deephaven’s loan origination system directly to Lightning Docs, allowing DSCR loan packages to be generated in seconds and eliminating manual data entry.
“Lightning Docs not only delivered the right documents — they continue to be an ongoing partner in helping us navigate the regulatory landscape for business-purpose loans,” said Dank Pinckney, Deephaven’s general counsel and chief compliance officer.
From Pilot To Scale
The impact is already showing up in volume.
Deephaven said it closed just 16 DSCR loans using the platform in May 2023. Within five months, that number nearly doubled. After a year, production reached 199 loans. Today, the lender is closing more than 300 DSCR loans per month through the system.
That trajectory signals more than incremental improvement; it marks a shift from testing DSCR workflows to operating them at scale.
The company has also produced DSCR loan documents across all 50 states and Washington, D.C., positioning the platform for nationwide investor lending.
Why It Matters
For LOs, the play is straightforward: faster document generation means faster closings, and in investor lending, speed often determines who wins the deal.
It also has direct margin implications.
By automating document creation and reducing manual touches, lenders can lower cost per loan while increasing file throughput per operations staff — a key advantage in DSCR lending, where efficiency and turn times can make or break profitability.
More importantly, the ability to consistently execute at speed allows lenders to compete more aggressively for investor business, where borrowers are often juggling multiple offers and tight timelines.
The move highlights a broader shift in the Non-QM space: scaling production is no longer just about adding products, it’s about building infrastructure that can handle volume without slowing down.
“Deephaven’s success highlights what’s possible when Non-QM lenders take a deliberate approach to DSCR lending,” said Nema Daghbandan, CEO of Lightning Docs.
As DSCR lending continues to grow, the competitive edge is increasingly shifting to lenders that can deliver both speed and consistency, not just product availability.
