    • Fixed Rate: Unchanging interest rate for the loan term.
    • Adjustable Rate: Starts with a fixed period, then adjusts based on market conditions.
  • Loan Term: Commonly 15, 20, or 30 years; determines repayment duration.
  • Loan Amount: Property price minus down payment.
  • Repayment: Includes principal and accrued interest, paid monthly.
  • Closing Costs: Fees for loan processing, title, appraisal, and more (2%-6% of the loan amount).
