Terminology Index

Core Operational Definitions

Adjustable Rate Mortgage (ARM)

A debt instrument where the interest rate is linked to the lender's Prime Rate. In this configuration, the monthly payment fluctuates automatically in direct correlation with central bank rate shifts. This ensures the principal reduction remains constant while the interest component scales with the market.

Closed Mortgage Protocol

A restrictive lending agreement that limits the borrower's ability to liquidate the debt before the maturity date. Any breach of this protocol via early repayment triggers a liquidation penalty, calculated as either three months' interest or the Interest Rate Differential (IRD). More details are available in the Prepayment and Liquidation Protocols section.

Loan-to-Value (LTV) Ratio

A mathematical assessment of lending risk. It is the quotient of the total loan amount divided by the appraised value of the collateral. Ratios exceeding 80% require mandatory default insurance as dictated by the Federal Stress Test Algorithm.

Computation Modules

Mathematical Logic

Interest Rate Differential (IRD)

Calculation used for fixed-rate liquidation. IRD = Principal × (Contract Rate - Current Market Rate) × (Remaining Term / 12).

GDS/TDS Ratios

Gross Debt Service (GDS) must not exceed 32-39% of gross income. Total Debt Service (TDS) is capped at 40-44% depending on credit score.
