Buying your first home requires careful financial planning. Key mortgage terms include principal, interest, amortization, and equity. Mortgage types include fixed-rate, adjustable-rate, and government-backed loans. Preparation involves assessing financial health, saving for a down payment, and budgeting for extra costs. First-time buyers should get pre-approved, understand options, and negotiate terms. Specialized loans exist for low-income, poor credit, and self-employed buyers.
