One policy answers mortgage eligibility and price in one run

The guideline and rate sheet live in separate documents, and changes wait on a vendor. Decisimo automates both in one run, from a policy your credit team edits.

The guideline and rate sheet become one policy

Eligibility and price

Decisimo runs both in one decision flow from the credit team's policy

Editable par rate

The credit team changes a cell, then releases the policy

Second lien grid

A lien fork selects the lender's combined loan to value bands

Plain-language reasons

Each outcome row records why the policy reached its decision

Written exceptions

Two rules test compensating factors and set approve or refer

Change impact

Saved cases rerun to show which past decisions a change moves

One run from application to priced decision

  1. Application arrives

  2. Qualifying score

  3. Eligibility knock-outs

  4. Debt to income

  5. Lien and par grid

  6. Adjustments and floor

  7. Approve, refer or decline

The par rate grid the credit team edits

  • Sixteen priced cellsScore bands run down the side, with loan to value bands across
  • Outside the gridNo cell writes a price, so Decisimo refers the file to a person
  • Adjustments and floorScorecard points are rate points, and the floor sets the minimum
First lien par rate grid showing qualifying score and loan-to-value bands, par rates, and priced-cell descriptions
First lien par rate places the outside-every-cell row before its sixteen priced cells.

The qualifying score comes from the run

  • Score selectionThe policy takes the middle of three, the lower of two, or the one returned
  • Formula editorEach one is made in the portal editor, with no code
  • No-score pathThe policy refuses no-score applications above its exposure limit
Custom function editor for “Middle of three scores”, with the formula and three score attribute mappings
Middle of three scores uses the three bureau scores bound in the formula editor.

A closed-end second the lender can define

  • Lien positionAn unspecified lien takes neither path and receives no price
  • Second-lien gridCombined loan to value sets its bands, with separate adjustments
  • Shared debt to incomeThe calculation includes the first lien payment
Second-lien par-rate decision table matching qualifying score and combined loan-to-value bands to par rates
Second lien par rate keys its grid to qualifying score and combined loan to value.

The debt to income exception has two rules

  • Compensating factorsThe test checks score, exposure, reserves and loan purpose
  • Two written rulesOne fires if any factor is missing. The other fires only if all hold.
  • Approve or referAbove the limit, the row records which outcome applies
Debt-to-income exception rule editor showing missing compensating factors and four ANY conditions

Change a cell and see which loans it moves

  • Revision historyThe version that priced a loan months ago stays readable
  • Regression testsSaved cases rerun, and past decisions show which ones a change moves
  • Release sign-offAn endpoint can require a signature before deployment

Turn policy into a decision flow

What the lender owes and the run records

  • Regulation BA declined applicant gets specific reasons. The row is not the notice.
  • Regulation ZThe run records the inputs considered in the good-faith determination
  • Points and feesThe run computes the loan-amount ratio used in a high-cost test

What stays with the lender

  • Demo figuresRates, bands and thresholds shown belong to a demo case
  • Lender's policyDecisimo runs that policy on the data the lender supplies
  • Human workPeople handle documents and appraisal. They also verify.

Questions we get asked

What is a mortgage pricing engine?

A mortgage pricing engine applies a lender's pricing rules to an application and returns a price. Decisimo answers eligibility and price in the same run, from the lender's policy.

Can I price a closed-end second with my own policy?

A lender can write a closed-end second lien's par grid and adjustments as its own policy. Decisimo runs it alongside the first-lien path.

How does underwriting handle one score or no score?

The policy uses the sole returned score when one is available. With no score, eligibility refuses the application above the exposure the policy allows.

What happens when an application is referred?

A person works the referral as a case, with the same rules available inside it. Work referrals as cases
