## Methodology

Safe Rate calculates these rankings using a risk-adjusted, data-driven scoring system based on Home Mortgage Disclosure Act (HMDA) filings. Rather than relying on simple averages, our statistical models control for loan-level risk factors (such as LTV, loan amount, and property value) to evaluate a lender's true competitiveness within Decatur, IL.

Our composite SafeRate Score is derived using an equal, geometric weighting of the following factors:
1. **Pricing:** Evaluates the lender's interest rates and net fees relative to the market.
2. **Pull-Through:** Measures the percentage of applications that successfully close, indicating reliability and customer service.
3. **Product Knowledge:** Evaluates the lender's specific experience and volume originating the selected loan product.
4. **Local Place Knowledge:** Analyzes the lender's total number of loans originated in the specific geography to determine local market expertise.
