Mortgage Portfolio Monitoring

Know when your collateral hits the market — every week.

Weekly property-level signals across the entire Canadian residential market. Match BrightCat's pipeline against your mortgage book and you'll see every listing, every price change, every sale on a property you're financing — 4 to 12 weeks before discharge.

By the time the discharge request arrives, the property has been on the market for two months. BrightCat puts you on it in week one.

The problem

Mortgage runoff happens before lenders see it

A mortgage discharge is a lagging signal. By the time the discharge request lands at the bank, the property has been listed, shown, negotiated, and is days from closing. The retention conversation has already been lost.

For Canadian federally regulated lenders, mortgage retention is a structural problem. Renewals get shopped, refinances go to brokers, and discharges follow property sales the lender didn't know about until it was too late. The signal that the borrower was leaving was visible weeks earlier — on the property listing — but didn't make it into the lender's data environment.

The bank already holds the address, the borrower record, and the loan terms. What it doesn't hold — and historically couldn't easily acquire — is a weekly, property-level view of what's happening on the asset side of the book. BrightCat is the missing layer.

How it works

Joining BrightCat to your mortgage book

The match key is the property — not the borrower, not the loan number, not the credit file. Properties have persistent identifiers; borrowers move, refinance, and change names.

1. Standardise your address book
Your mortgage book is joined against BrightCat's 12M+ Canadian address master. Persistent property identifiers are assigned to every loan, surviving relisting cycles and MLS number changes.
2. Weekly signal delivery
Every Sunday, BrightCat refreshes listing status, price changes, lifecycle events, and sold-confirmation flags for every property in the join. The bank receives delta files highlighting newly listed properties in its book.
3. Trigger retention workflows
New listing events fire retention outreach. Price reduction events trigger refinance conversations. Sold-confirmation events update discharge probability scores in the portfolio model.
4. Closed-loop validation
When a discharge eventually arrives, BrightCat's prior-listing date gives the bank a lead-time audit. The portfolio model learns which signals best predict actual discharge versus relist-and-stay.
Signal types

What you'll see on the book each week

Six recurring signal types BrightCat fires on properties securing active mortgages.

New listing
A property in your mortgage book has appeared on the market. Lead time to discharge typically 4–12 weeks.
Price reduction
An active listing has dropped its asking price. Signal of motivated seller, often precedes a sale within 2–4 weeks.
Extended on market
Cumulative days on market crosses a threshold. May signal market headwind, mispricing, or seller flexibility.
Withdrawn / relisted
Listing pulled and re-entered the market — borrower remains in the property, refinance conversation still open.
Sold confirmation
Listing transitioned to sold status with confirmed price. Discharge incoming; opportunity to capture the next mortgage at the new property.
Rental conversion
Owner-occupied property appears as a rental listing — likely investor conversion. Implications for occupancy assumptions and rate.
Use cases

What banks actually do with this

Discharge prediction modelling
Replace the 30/60/90-day discharge probability score that was built on credit-bureau signals alone. Listing-event features substantially improve lead time and accuracy.
Retention outreach prioritisation
Trigger retention campaigns the week a property is listed rather than the week the renewal notice goes out. Higher-quality outreach because the customer is genuinely transacting.
Mark-to-market portfolio valuation
Combine listing-active data with BrightCat HPI to refresh loan-to-value calculations on the portfolio without commissioning new appraisals.
Collateral exposure flagging
When properties securing high-LTV mortgages appear with price reductions, flag for credit risk review. Early warning before delinquency emerges in the loan record itself.
Refinance origination targeting
Identify properties that have transacted in your geographic markets in the past 12 weeks — new mortgages currently being shopped. Cross-reference against your application pipeline to estimate addressable refinance volume.
Stress testing & regulatory reporting
Historical 12-year repeat-sale appreciation distributions feed regulatory stress scenarios for OSFI submissions and internal capital adequacy assessments.
Governance

Built for federally regulated lenders

Documented methodology, versioned builds, per-record lineage. The procurement and model-risk paperwork was anticipated.

BrightCat's pipeline has produced a versioned weekly build every week since 2014 without interruption. Each build carries a build identifier, capture-window timestamps, and per-record lineage tying every signal back to its source observation. For institutions running OSFI Guideline E-23 model risk reviews, Treasury Board Directive on Automated Decision-Making assessments, or internal AI governance audits, this matters: the data layer is documented, reproducible, and auditable.

Production deployments operate under an annual Master Data License Agreement (MDLA) with defined audit rights, AI/ML usage clauses, and lifecycle terms. Sample data evaluation is free and runs under a standard NDA. Full methodology documentation, including the persistent property identifier construction, is available under NDA for procurement and model-risk teams. Methodology proof page →

FAQ

Common questions from lenders

What is mortgage portfolio monitoring?+

Mortgage portfolio monitoring is the practice of continuously tracking the status of properties securing an active loan book. For Canadian federally regulated lenders, this typically includes listing detection, price change tracking, sold-event confirmation, and discharge prediction.

How does BrightCat detect when a mortgaged property hits the market?+

BrightCat captures property-level listing events weekly across all 10 Canadian provinces. By joining the lender's mortgage book on standardised address and persistent property identifier, BrightCat flags every listing in the book typically 4–12 weeks before discharge.

How is this different from credit bureau monitoring?+

Credit bureau monitoring captures the borrower side. Property listing monitoring captures the asset side — the property is on the market before the borrower applies anywhere. The two are complementary, but property listing typically leads credit inquiry by weeks.

Can BrightCat support OSFI Guideline E-23 model risk requirements?+

BrightCat's pipeline is documented end-to-end with versioned weekly builds, per-record lineage, and methodology documentation available under NDA for model risk reviews.

How is the data delivered?+

Snowflake Marketplace with Secure Data Share, MCP connector, flat file (CSV / Parquet) to the bank's cloud storage, or hashed match-and-return for institutions with outbound data constraints.
