To get a first-time homebuyer's budget, start by calculating your Debt-to-Income (DTI) ratio, then use rules like the 28% rule (housing costs < 28% of gross income) or the 3x income rule (house price < 3x income) as guides, factor in all potential housing costs (mortgage, taxes, insurance, HOA, utilities, repairs), and save aggressively for a down payment (5-20%) and closing costs (2-5%), while also building an emergency fund.
