Core Viewpoint - The decision between full payment and mortgage for home buying depends on individual financial situations and life plans, with each option having its own advantages and disadvantages [1][5][8] Group 1: Financial Flexibility - Full payment reduces monthly repayment pressure, leading to greater financial ease but locks a significant amount of capital in real estate, reducing liquidity [1][5] - Mortgage allows for retaining some capital for other investments, enhancing financial flexibility, especially in uncertain economic conditions [3][5] Group 2: Investment Perspective - From an investment standpoint, using a mortgage can be more attractive as it allows for potential higher returns from other investments while leveraging borrowed funds [3][5] - The opportunity cost of using all available funds for a full payment limits growth potential [3] Group 3: Interest Costs and Tax Benefits - The main drawback of mortgages is the interest cost, which can be significantly higher than the total cost of full payment [3] - Some regions offer tax benefits for mortgage interest, which can lower overall housing costs, making it essential to understand local tax policies [3] Group 4: Lifestyle and Psychological Impact - Full payment alleviates monthly repayment stress, allowing buyers to focus on quality of life, while mortgages can impose long-term financial pressure affecting lifestyle and mental health [5][7] - The choice of payment method should align with personal financial health and life quality [5][7] Group 5: Inflation and Market Risks - Inflation can reduce the real cost of loans, making mortgages more appealing in high inflation environments, while full payment may lead to a decrease in purchasing power [5][8] - Market volatility poses risks, with full payment buyers facing greater exposure to price fluctuations compared to those using mortgages [5][8] Group 6: Repayment Capacity and Future Planning - Mortgage repayment requires stable income and career progression, which can be a burden if income fluctuates [7] - Family structure and future financial needs should influence the choice between full payment and mortgage, with younger buyers potentially benefiting from retaining liquidity for future expenses [7] Group 7: Personal Preferences and Risk Tolerance - The choice between full payment and mortgage ultimately depends on individual risk tolerance, with risk-averse individuals preferring full payment for security [8] - Risk-tolerant individuals may opt for mortgages to leverage their investments for wealth accumulation [8]
