- Mortgage

A loan secured by real property, where the lender can take the home if the borrower fails to repay. The property itself serves as collateral for the debt.
- Collateral
- Related: Mortgage, Loan-to-Value Ratio, Foreclosure
An asset pledged to secure a loan. In residential lending, the home and land secure the mortgage, allowing the lender to recover funds if the borrower stops paying.
- Principal
- Related: Interest Rate, Amortization, Equity
The amount of money borrowed, separate from interest and fees. As payments are made, the outstanding principal balance declines, building the borrower's equity over time.
- Interest Rate
- Related: Principal, Amortization, Annual Percentage Rate
The percentage a lender charges on the outstanding loan balance, expressed annually. It determines the cost of borrowing and shapes the monthly payment amount.
- Amortization
- Related: Principal, Interest Rate, Monthly Payment
The schedule by which a loan is paid down over time through regular payments split between principal and interest. Early payments are mostly interest; later payments are mostly principal.
- Loan-to-Value Ratio (LTV)
- Related: Collateral, Private Mortgage Insurance, Appraisal
The loan amount divided by the property's appraised value or purchase price, whichever is lower. Higher ratios signal greater lender risk and often trigger mortgage insurance requirements.
