To compare mortgage options, start by reviewing your income, debts, and debt-to-income ratio (some lenders may look for around 36%, but it varies). Learn common mortgage types (fixed, adjustable, FHA, VA, USDA, jumbo, or interest-only) and how they work. Check your credit score, think through a housing budget using general guidelines like the 28%-36% rule, and consider down payment choices (20% is often cited, but not required). When comparing offers, look at rates, fees, and APRs, and ask what factors may affect pricing and terms. Many buyers get a pre-approval before house hunting, then make an offer, schedule a home inspection, complete the loan application, go through underwriting, attend closing, and move in.
