Preparing financially before buying a home is crucial. Upfront costs include the down payment, which can be as low as 3-5% depending on the loan type, plus inspections, appraisal, and closing costs. Savings should cover these and monthly mortgage payments. Review your budget and calculate your debt-to-income ratio to ensure affordability. Maintain a good credit score by avoiding new credit and checking for errors. Proper planning sets you up for successful homeownership.
