How Much House Can I Afford? 2026 Affordability Guide

The First Question Every Home Buyer Asks

“How much house can I afford?” is the starting point of every home-buying journey. The answer determines which neighborhoods to look in, how much to save for a down payment, and whether buying even makes sense right now.

In 2026, affordability is tighter than in recent memory. Mortgage rates remain elevated (6–7% for 30-year fixed), home prices are still near all-time highs in many markets, and the cost of living has risen across the board. But that does not mean homeownership is out of reach — it just means you need to run the numbers carefully. This guide shows you exactly how.

The Two Rules That Determine Affordability

Lenders use two main ratios to decide how much they will lend you. Understanding these is the key to knowing your budget.

The 28% Rule (Housing Cost Ratio)

Your total monthly housing costs — including principal, interest, property taxes, and insurance (PITI) — should not exceed 28% of your gross monthly income.

If your household earns $120,000/year ($10,000/month):

The 36% Rule (Total Debt Ratio)

Your total monthly debt payments — housing plus car loans, student loans, credit card minimums, child support, and other obligations — should not exceed 36% of your gross monthly income.

With $500 in monthly car payments and $300 in student loans:

In this case, both rules agree at $2,800/month.

From Monthly Payment to Home Price

Once you know your maximum monthly housing payment, you can work backward to find the home price you can afford. Here is how it works for a 30-year fixed-rate mortgage at 6.5%:

Example 1: $100,000 Annual Income, $40,000 Down

• Monthly income: $8,333
• Max housing payment (28%): $2,333
• Minus ~$200 for taxes and ~$80 for insurance: leaves ~$2,053 for P&I
• At 6.5% over 30 years, $2,053/month supports a loan of ~$325,000
• Plus $40,000 down payment
• Max home price: ~$365,000

Example 2: $150,000 Combined Income, $80,000 Down

• Monthly income: $12,500
• Max housing payment (28%): $3,500
• Minus ~$350 for taxes and ~$120 for insurance: leaves ~$3,030 for P&I
• At 6.5% over 30 years, supports a loan of ~$480,000
• Plus $80,000 down payment
• Max home price: ~$560,000

Example 3: $200,000 Income, $150,000 Down (Jumbo Loan)

• Monthly income: $16,667
• Max housing payment (28%): $4,667
• Minus ~$500 for taxes and ~$150 for insurance: ~$4,017 for P&I
• At 6.5% over 30 years, supports a loan of ~$635,000
• Plus $150,000 down
• Max home price: ~$785,000
• Note: Jumbo loans (above $766,550 in most areas in 2026) may require larger down payments and higher credit scores.

The Down Payment: How Much Do You Really Need?

The “20% down” rule is a guideline, not a requirement. Here are your options:

• 3% down: Conventional loans through Fannie Mae or Freddie Mac allow as little as 3% down for first-time buyers with good credit (620+).
• 3.5% down: FHA loans require just 3.5% down with a credit score of 580+. The trade-off is upfront MIP (1.75% of loan amount) and annual MIP for the life of the loan.
• 0% down: VA loans (for eligible veterans and active military) and USDA loans (for rural properties) require zero down payment.
• 5%+ down: Many conventional lenders prefer at least 5% down. You also avoid the lowest credit score tiers.
• 20% down: Eliminates PMI entirely, saving you 0.3–1.5% of the loan amount per year.

For Canadian buyers, the minimum down payment is:

• 5% for homes up to $500,000
• 10% for the portion between $500,000 and $1,000,000
• 20% for homes over $1,000,000
• Below 20% down requires CMHC mortgage default insurance (added to the mortgage)

Canadian Affordability: The GDS/TDS Rules

Canada uses a different qualification framework. The mortgage stress test requires you to qualify at the higher of your contract rate + 2% or the Bank of Canada's qualifying rate.

Gross Debt Service (GDS) Ratio

GDS = (Mortgage payment + property taxes + heating + 50% of condo fees) ÷ Gross income. Must be ≤ 39%.

Total Debt Service (TDS) Ratio

TDS = (Housing costs + all debt payments) ÷ Gross income. Must be ≤ 44%.

Example: Buyer in Toronto, $120,000 CAD Income

• Monthly income: $10,000 CAD
• Max GDS (39%): $3,900 for housing costs
• Stress test rate: 5.25% (Bank of Canada qualifying rate)
• Assuming $60,000 down and $500/month in other debts:
• Max TDS (44%): $4,400 total, leaving $3,900 for housing
• At the stress test rate, supports a home of roughly $500,000–$550,000 CAD

Hidden Costs That Shrink Your Budget

Your monthly payment is not the full picture. These costs reduce what you can truly afford:

• Closing costs: 2–5% of the purchase price. On a $400,000 home, that is $8,000–$20,000 in upfront cash.
• Homeowners insurance: $800–$2,000/year depending on location, coverage, and the home.
• Property taxes: 0.5%–2.5% of assessed value per year. A $400,000 home in New Jersey (2.5%) costs $10,000/year in taxes alone.
• HOA fees: $100–$600/month for condos, townhomes, or planned communities.
• Maintenance: Budget 1–2% of the home value annually. On a $400,000 home: $4,000–$8,000/year.
• Utilities: Typically 20–50% higher in a house compared to an apartment.
• Moving expenses: $1,000–$5,000 depending on distance and whether you hire movers.

A good rule of thumb: your total cash needed at closing should include down payment PLUS 3–6% of the purchase price for closing costs and immediate post-move expenses.

Rent vs. Buy: When Does It Make Sense?

Just because you can afford a house does not mean you should buy one right now. The rent vs. buy decision depends on:

• How long you plan to stay: Typically need 5–7 years to break even on transaction costs.
• Local market conditions: Price-to-rent ratios vary dramatically by city.
• Opportunity cost of down payment: Money used for a down payment could instead be invested.
• Monthly cash flow comparison: Compare PITI to your current rent, including maintenance reserves.
• Future appreciation assumptions: Optimistic vs. conservative estimates change the math significantly.
