How Much House Can I Afford? The Complete Guide (2026)
Buying a home is the biggest financial decision most people will ever make. Before you start scrolling through real estate listings and falling in love with kitchens you cannot afford, you need to answer one critical question: how much house can I actually afford? Getting this number wrong can lead to years of financial stress, while getting it right sets you up for long-term stability and wealth building.
The 28/36 Rule: Your Starting Point
Financial experts have long recommended the 28/36 rule as a baseline for housing affordability. The rule states that your monthly housing costs should not exceed 28% of your gross monthly income, and your total debt payments (including the mortgage) should stay below 36% of gross income. For example, if your household earns $6,000 per month before taxes, your mortgage payment, property taxes, and homeowners insurance combined should be no more than $1,680. If you also have a $300 car payment and $200 in student loans, your total debt load reaches $2,180 ā which is right at the 36% threshold.
Why Gross Income Is Not the Whole Picture
The 28/36 rule uses gross income, but you do not pay bills with gross income. After federal taxes, state taxes, Social Security, health insurance, and retirement contributions, your take-home pay might be 60-70% of your gross salary. A more conservative approach is to ensure your housing payment does not exceed 25-30% of your net take-home pay. This leaves breathing room for savings, emergencies, and the things that make life enjoyable.

The Down Payment Factor
Your down payment directly determines the price range you can consider. A 20% down payment on a $400,000 home is $80,000, leaving you with a $320,000 mortgage. That same $80,000 as a 10% down payment lets you target a $800,000 home ā but your monthly payment jumps significantly, and you will likely need private mortgage insurance (PMI), adding $100-300 per month. Conventional wisdom says 20% avoids PMI, but many first-time buyers start with 3-5% down through FHA or conventional low-down-payment programs. The trade-off is higher monthly costs.
Hidden Costs Most Buyers Forget
The purchase price is just the beginning. Property taxes vary wildly by location ā from 0.3% of home value in Hawaii to over 2% in New Jersey and Illinois. Homeowners insurance typically runs $1,200-3,000 per year, more in disaster-prone areas. Then there is maintenance: experts recommend budgeting 1-2% of the home value annually for repairs and upkeep. A $350,000 home might need $3,500-7,000 per year in maintenance ā that is $290-580 per month you need to account for. HOA fees, if applicable, can add another $200-500 monthly. None of these show up in a basic mortgage quote, but they all come out of your pocket.
How Your Credit Score Affects Affordability
Your credit score does not just determine whether you get approved ā it directly impacts your interest rate, which dramatically changes your monthly payment. On a $300,000 30-year mortgage, the difference between a 6.0% rate (excellent credit) and a 7.5% rate (fair credit) is roughly $300 per month, or $108,000 over the life of the loan. Before house hunting, check your credit report, dispute any errors, and spend 6-12 months improving your score if it is below 700. Every point matters when you are borrowing hundreds of thousands of dollars.
Debt-to-Income Ratio: What Lenders Actually Look At
Lenders care deeply about your debt-to-income ratio (DTI). They add up all your monthly debt obligations ā car loans, student loans, credit card minimum payments, personal loans ā and divide by your gross monthly income. Most conventional lenders want to see a DTI below 43%, though some allow up to 50% for borrowers with strong compensating factors. If your DTI is too high, you have two options: pay down existing debt or increase your income. Even paying off a $300/month car loan can significantly increase your borrowing power.
A Practical Formula You Can Use Today
Here is a straightforward approach: Take your annual household income and multiply by 3 to 4.5. That gives you a rough home price range. A family earning $100,000 per year can generally afford a home between $300,000 and $450,000. Then refine the number with our free Mortgage Calculator at money.now.to. Enter different home prices, down payments, interest rates, and loan terms to see exactly what your monthly payment would be. Compare that payment against 25-30% of your take-home pay to find your comfort zone.
What About Interest Rates?
Interest rates fluctuate constantly and have a massive impact on affordability. In 2020, rates near 3% meant a $400,000 home cost about $1,350 per month in principal and interest. In 2026, with rates around 6-7%, that same home costs $2,130-2,260 per month. That is a difference of nearly $900 per month ā or $10,800 per year ā for the exact same house. When rates are high, you may need to adjust your price range downward or plan to refinance when rates eventually drop.
The Emergency Fund Requirement
Before buying, ensure you have an emergency fund beyond your down payment. Financial advisors recommend 3-6 months of expenses, but as a new homeowner, aim for 6 months. Home emergencies ā a failed furnace, a leaking roof, a broken water heater ā do not wait for convenient timing. If your emergency fund is depleted by the down payment and closing costs, you are one appliance failure away from credit card debt.
Bottom Line
The amount of house you can afford depends on income, debts, down payment, credit score, interest rates, and the hidden costs of homeownership.
