Home Affordability Calculator

How Much House Can You Really Afford?

Buying a home is likely the most significant financial decision you will ever make, with implications that extend for decades. While mortgage lenders may approve you for a substantial loan amount based on your income and credit, what you qualify for and what you can comfortably afford are often dramatically different figures. Understanding the true, comprehensive cost of homeownership is essential to avoid becoming house poor, a frustrating situation where your home consumes so much of your income that you cannot adequately save for retirement, handle emergencies, or enjoy life. This calculator helps you determine a realistic budget based on established lending guidelines. Read our complete affordability guide →

The 28/36 Rule: Industry Standard for Affordability

Most mortgage lenders use the 28/36 rule as the benchmark for determining borrower affordability. The first number, 28, means your total housing costs including principal, interest, property taxes, homeowners insurance, and HOA fees should not exceed 28% of your gross monthly income. The second number, 36, means your total debt payments, including housing plus car loans, student loans, credit card minimums, and other recurring debts, should not exceed 36% of your gross income. While some lenders approve higher ratios (up to 43-50% for qualified borrowers), staying within the 28/36 limits provides essential financial breathing room for savings, emergencies, and lifestyle expenses.

The Hidden and Ongoing Costs of Homeownership

Property Taxes: Property tax rates vary dramatically by location, ranging from 0.5% to over 2.5% of your home's assessed value annually. In high-tax areas, property taxes can add $500-$1,000 or more to your monthly housing costs on a typical home. Research tax rates carefully in your target neighborhoods, as this single factor can significantly impact affordability.

Maintenance and Repairs: Experts recommend budgeting 1-2% of your home's value annually for maintenance and repairs. For a $400,000 home, that means setting aside $4,000-$8,000 each year. This covers routine maintenance like HVAC servicing, gutter cleaning, and landscaping, plus inevitable major replacements. Roofs cost $8,000-$20,000+, HVAC systems $5,000-$15,000, and water heaters $1,000-$3,000. These costs are often overlooked by first-time buyers.

Private Mortgage Insurance (PMI): If your down payment is less than 20%, lenders require PMI to protect themselves against default. PMI typically costs 0.5-1% of your loan amount annually, adding $100-$300+ to your monthly payment on a typical loan. You can request PMI removal once you reach 20% equity through payments or home appreciation. Use our Mortgage Calculator →

Making the Rent vs. Buy Decision Wisely

Contrary to popular belief, buying a home is not always financially superior to renting. The smart decision depends on several factors: how long you plan to stay in the area (buying typically only makes sense if you will stay 5+ years to recover transaction costs), local housing market conditions and price-to-rent ratios, your need for lifestyle flexibility and mobility, and your readiness to handle homeowner responsibilities. In expensive coastal markets or during housing bubbles, renting and investing the difference often produces better long-term wealth outcomes.
