Buying a home is a major investment, and avoiding common mistakes is essential. Key errors include delaying lender contact, buying while in debt, and careless credit use. First-time buyers often wrongly assume a 20% down payment is necessary, overlooking government-insured loans. Rushing, ignoring extra costs, and neglecting neighborhood considerations can lead to regret. Conducting inspections, prioritizing structural integrity, and documenting details are crucial. Professional help can simplify the process and prevent costly errors.
