Credit Appraisal Co-pilot for Affordable Home Loans

A GenAI co-pilot that reads the whole loan file, from twelve months of bank statements to the legal and technical reports, and drafts the credit appraisal memo. The underwriter still makes the decision, in minutes instead of hours.

The Challenge

Informal income, formal paperwork, manual underwriting

In affordable housing, many applicants are self-employed or paid partly in cash. Proving income means reading the bank statement line by line, and every file was done by hand.

Hours per file

Underwriters read 6 to 12 months of statements, ITRs, payslips and property papers, then typed the memo. About 3.5 hours a file.

Inconsistent income calls

Two underwriters could assess the same kirana owner's income differently. Cash deposits and one-off credits were treated case by case.

Back-and-forth with branches

Missing documents surfaced only at credit review. Files went back to the branch, sometimes twice, adding days to turnaround.

Red flags hidden in volume

A single bounced EMI or a pattern of round-figure cash deposits was easy to miss among four hundred transactions.

HMC Approach

AI reads and drafts. The underwriter decides.

The co-pilot works inside the housing finance company's credit policy. Every number in the memo links back to the page it came from.

Select a step to see what happened.

Discover · Shadow the underwriters

We sat with credit teams in regional hubs and timed every step of the file.

  • Mapped the journey from login to sanction for salaried and self-employed files.
  • Found that two-thirds of underwriter time went on reading and re-typing.
  • Collected the most common reasons files went back to branches.

Deliverable: Time-and-motion study and file-rework map.

Design · Policy first

Credit policy became the rulebook the co-pilot follows.

  • Income assessment methods by profile: salaried, trader, transport operator.
  • FOIR and LTV limits, obligation-exclusion rules and deviation triggers.
  • The existing CAM format, section by section, so nothing changes for approvers.

Deliverable: Policy rule-pack and CAM template signed off by Credit.

Build · Read, classify, assess, draft

Claude does the reading and drafting; deterministic rules do the maths.

  • Document reading for statements, ITRs, payslips, bureau, legal and technical reports.
  • Every transaction classified, with bounces, cash patterns and obligations flagged.
  • Draft CAM with red flags, each linked to its source page.

Deliverable: Co-pilot in a controlled environment, with an audit trail.

Adopt · Side by side, then in charge of the draft

Underwriters ran the co-pilot in parallel before relying on it.

  • Four weeks of side-by-side memos; differences reviewed each Friday.
  • Branch checklist generated on day one, so missing papers are asked for early.
  • Credit managers approve from the same memo, with sources one click away.

Deliverable: Live in pilot hubs, with underwriter feedback loop.

Scale · More profiles, more products

The same engine now supports more of the book.

  • Rolled out to more affordable and emerging-market hubs.
  • Extending to loan against property and balance transfers.
  • Early-warning signals from the same transaction model for portfolio monitoring.

Deliverable: Rollout plan and model-monitoring dashboard.

The Solution

Watch the co-pilot appraise a file

Choose an applicant and press Run co-pilot. It reads the file, classifies a year of transactions, assesses income, checks eligibility against policy and drafts the memo. Then take over: drag the loan on the eligibility chart, switch the transaction view or click a red flag.

Each dot is one transaction; size is the amount. Switch to the AI view to sort them into what they are.

3Monthly cash flow and assessed income

Inflows above the line, outflows below. The orange line is income as assessed under policy for this profile.

Income consistency

Each petal is a month of assessed income; the dashed ring is the median. Green is within 15% of it.

4Eligibility against policy

The shaded area is every loan and tenure the applicant qualifies for. Drag the dot, or use the sliders.

Key Takeaways

What transfers to any credit team

01

Let AI read, let people judge

The biggest time sink was reading and typing, not deciding. Take that away and underwriters spend their time on the judgement calls.

02

Policy is the prompt

Encoding the credit policy as rules made the co-pilot consistent, explainable and easy for risk to sign off.

03

Every number needs a source

Linking each figure and flag to its page is what earned the trust of approvers and auditors.
