How accurate are CDR-based pre-approval amounts compared to formal approval?

Pre-approvals using CDR-verified data typically fall within 5-10% of formal approval amounts, compared to 15-25% variance with traditional self-declared methods. The closer alignment reduces borrower disappointment and rework.

What documents does the borrower still need to provide?

With CDR data covering income, expenses, and commitments, borrowers typically only need to provide identity documents (driver licence or passport) and property-specific items like the contract of sale. This reduces the document list from 8-12 items to 2-3.

Can pre-approvals be refreshed without the borrower re-consenting?

Yes, if the borrower granted ongoing CDR consent, you can refresh their financial data at any time to update the pre-approval. This is particularly useful for pre-approval renewals at the 90-day mark.

Does this work for investment property applications?

Yes, the API captures rental income from existing investment properties and can assess total financial position including multiple income streams and property-related expenses for investment loan pre-approvals.

How do lenders view CDR-backed pre-approvals versus traditional ones?

Lenders increasingly prefer CDR-backed submissions because the data is tamper-proof and comprehensive. Several major lenders have established fast-track assessment pathways for applications accompanied by CDR-verified financial data.

Banking API — Mortgage Brokers

Instant Mortgage Pre-Approval with CDR Bank Data

Deliver same-day mortgage pre-approvals by combining CDR-verified income, expense analysis, and commitment detection into a complete financial picture. Reduce document requirements and accelerate borrower readiness.

In competitive property markets, the speed of pre-approval determines whether your clients win or lose at auction. Traditional pre-approval requires weeks of document collection and manual assessment. Fiskil enables mortgage brokers to generate pre-approvals in minutes by pulling a complete financial picture directly from borrower bank accounts through CDR — verified income, actual expenses, existing commitments, and deposit evidence in a single consent flow.

The Challenge

The traditional pre-approval process is too slow for the pace of Australian property markets, and the document burden drives borrower drop-off.

The Solution

Fiskil combines income verification, expense analysis, commitment detection, and deposit tracking into one API call, enabling brokers to assess pre-approval readiness in real-time.

Implementation

How It Works

Borrower Initiates CDR Consent

During the initial consultation, the borrower completes a CDR consent flow covering all relevant bank accounts — typically taking under 2 minutes per institution.

Pull Complete Financial Profile

Fiskil retrieves 6-12 months of transaction data and generates a comprehensive financial profile covering income streams, expense categories, and existing commitments.

Assess Borrowing Capacity

The API calculates indicative borrowing capacity using verified figures, accounting for the borrower's actual financial position rather than estimates.

Issue Pre-Approval and Submit

Generate a pre-approval package with verified evidence and submit to the lender. The borrower is auction-ready within the same appointment.

In Practice
