Must-Know Rules, Formulas, Standards, or Principles

1. The formula for monthly mortgage payments: M = P[r(1+r)^n]/[(1+r)^n – 1], where M = monthly payment, P = principal loan amount, r = monthly interest rate, and n = number of payments.
2. The 28/36 rule: the borrower's debt-to-income ratio should not exceed 28% for housing expenses and 36% for total debt.
3. The concept of amortisation: the gradual reduction of the loan balance through regular payments.

Misconceptions

• Misunderstanding the difference between amortisation and interest-only payments.
• Ignoring the impact of fees and charges on the loan balance.

The Common Trap
