How Much House Can I Afford? The Complete Guide

Buying a home is the largest purchase most people ever make. Getting the budget wrong can trap you in financial stress for decades. This guide shows you exactly how to calculate what you can truly afford — not just what a lender will approve.

The Difference Between What You Can Borrow and What You Can Afford

Lenders will approve you for the maximum loan you qualify for — not the optimal amount for your financial wellbeing. Being "approved" for a $450,000 mortgage does not mean buying a $450,000 home is a good idea for your life. Lenders care about getting paid back; your financial comfort, retirement savings, and life goals are your responsibility to protect.

The real question is: what mortgage payment leaves you enough cash flow to save for retirement, handle emergencies, and enjoy your life without financial stress?

Key Takeaway

The safest home budget is one where the total monthly housing payment does not exceed 28% of your gross monthly income — and all debts combined stay below 36%.

The 28/36 Rule Explained

The 28/36 rule is the most widely used affordability guideline in personal finance:

  • 28% rule: Your total monthly housing cost (mortgage P&I + property tax + homeowner's insurance + HOA if applicable) should not exceed 28% of your gross monthly income.
  • 36% rule: Your total monthly debt payments (housing + car loans + student loans + credit card minimums) should not exceed 36% of your gross monthly income.

Example — $80,000 annual salary ($6,667/month gross):

  • Maximum housing payment: $6,667 × 28% = $1,867/month
  • Maximum total debt: $6,667 × 36% = $2,400/month
  • If you have a $400/month car loan: housing budget drops to $2,400 − $400 = $2,000/month

Salary to Home Price Guide

Annual SalaryMax Housing Payment (28%)Approximate Home Price (6.5%, 30yr, 20% down)
$50,000$1,167/mo~$155,000
$65,000$1,517/mo~$202,000
$80,000$1,867/mo~$249,000
$100,000$2,333/mo~$311,000
$120,000$2,800/mo~$373,000
$150,000$3,500/mo~$466,000
$200,000$4,667/mo~$622,000

Assumes 20% down payment, 6.5% rate, 30-year term, and approximately $300/month in property tax and insurance.

The Full Cost of Homeownership Beyond the Mortgage

First-time buyers consistently underestimate the true monthly cost of ownership. Here is a realistic breakdown for a $350,000 home with 20% down:

CostMonthly AmountAnnual Amount
Principal & Interest (6.5%, 30yr)$1,770$21,240
Property tax (1.2% of value)$350$4,200
Homeowner's insurance$120$1,440
Maintenance & repairs (1%/year)$292$3,500
Utilities (vs renting)$150$1,800
Total true cost$2,682$32,180

The mortgage payment alone is $1,770/month. The true cost is $2,682 — 51% higher. Build this into your budget from the start.

How Much Down Payment Do You Need?

Minimum down payments by loan type:

  • Conventional loan: 3–5% minimum, but 20% avoids PMI
  • FHA loan: 3.5% (credit score 580+) or 10% (score 500–579)
  • VA loan (veterans): 0% down payment
  • USDA loan (rural areas): 0% down payment

PMI (Private Mortgage Insurance) is required when you put down less than 20% on a conventional loan. It typically costs 0.5–1.5% of the loan amount annually — on a $280,000 loan that is $1,400–$4,200/year, or $117–$350/month. PMI is automatically removed when you reach 20% equity.

What Credit Score Do You Need?

Credit ScoreLoan Type AvailableRate Impact
760+All types, best ratesLowest available rate
720–759All conventional loansNear-best rates
680–719Conventional, FHA0.25–0.5% higher rate
640–679FHA, some conventional0.5–1% higher rate
580–639FHA (3.5% down)1–2% higher rate
Below 580Very limited optionsSignificantly higher or unavailable

A 1% rate difference on a $300,000 30-year mortgage changes your payment by about $170/month and total interest by roughly $61,000. Improving your credit score before applying for a mortgage is one of the highest-return financial moves you can make.

Frequently Asked Questions

Can I afford a house on a $50,000 salary?

Yes, depending on your location, down payment, and existing debts. At $50,000/year ($4,167/month gross), the 28% rule suggests a maximum housing payment of $1,167/month. At 6.5% and 30 years with 20% down, that supports a home price of approximately $155,000–$165,000. In many parts of the US this is achievable; in high-cost cities it may require a different approach such as a smaller property, FHA loan with lower down payment, or waiting to accumulate more savings.

Is it better to buy or rent?

The honest answer depends on: how long you plan to stay (under 3–5 years usually favours renting due to transaction costs), local price-to-rent ratios (high ratios favour renting), your financial stability, and personal preferences. The old notion that renting is "throwing money away" ignores opportunity cost — the down payment invested elsewhere, and the costs of ownership that renters avoid. Run the actual numbers for your situation rather than following a blanket rule.

How much should I save before buying a house?

Beyond the down payment, budget for: closing costs (2–5% of loan amount), moving costs ($1,000–$5,000), immediate repairs or updates, and a 3–6 month emergency fund that should not be depleted by the purchase. Buying a home should not leave you cash-poor — unexpected repairs in year one are common.
