What a mortgage broker LOS needs

Twelve things a loan origination system has to handle for a broker shop, taken from what wholesale lenders actually require at submission. Use it to judge any LOS, this one included.

How a broker loan moves

In the wholesale channel the broker takes the application, prices it across lenders, and submits it; the lender usually underwrites, discloses, and closes. A typical flow, from lenders' published broker guides:

  1. Take the application (the 1003, also called the URLA).
  2. Within a day of a complete application, export a MISMO 3.4 file and import it into the chosen lender's portal.
  3. Upload the fee worksheet and the signed loan options (anti-steering) disclosure.
  4. Pull or reissue credit and run DU or LPA through the lender's sponsorship.
  5. The Loan Estimate goes out within three business days: from the lender's disclosure desk, or from the broker for lenders that require it.
  6. Underwriting issues conditions; the broker's processor collects them.
  7. Clear to close, the Closing Disclosure, and closing.

The broker's LOS owns steps 1 to 4 and has to track the rest. That's where the checklist comes from.

4. AUS findingsDU or LPA, usually through the lender's sponsorship.Partly: record the findings. No direct DU or LPA connection, which needs agreements with Fannie Mae and Freddie Mac.

Questions to ask any LOS

  • Who owns it, and who pays it? A system owned by one lender, or paid by lenders to be in a marketplace, has a reason to favor someone.
  • Where does borrower data live, and can you take it with you? Ask for a full export, MISMO and documents, before you sign.
  • What does it cost at five loan officers? Seat prices multiply; so do per-loan fees.
  • Can it explain a price? Which adjustments applied, and why one lender beat another.
  • What happens if the company changes course? Closed systems can be repriced or shut down. Open source can be carried on by anyone.
