How Much House Can I Afford? 2026 Salary Calculator Guide
Quick Answer
Most lenders follow the 28/36 rule: your housing payment shouldn't exceed 28% of gross monthly income, and total debt shouldn't exceed 36%. For a $100K salary, you can typically afford a $350K-$400K home with 10-20% down.
One of the most common questions I hear from Seattle-area homebuyers is "How much house can I actually afford?" After two decades helping families navigate home purchases, I've seen too many buyers either stretch beyond their means or underestimate their buying power. Let me walk you through the proven formulas lenders use and what they mean for your 2026 home search.
The 28/36 Rule: Your Foundation for Home Affordability
Most mortgage lenders rely on the 28/36 rule to determine how much you can borrow:
- 28% Rule: Your total housing payment (principal, interest, taxes, insurance) shouldn't exceed 28% of your gross monthly income
- 36% Rule: Your total monthly debt payments (including the new mortgage) shouldn't exceed 36% of gross monthly income
These aren't just suggestions—they're typically hard limits that determine loan approval. However, some loan programs allow higher ratios, which I'll explain below.
How Much House Can You Afford by Salary?
Here's what different income levels can typically afford in today's market, assuming 15% down payment and current Seattle-area property taxes:
$75,000 Annual Salary
- Maximum monthly housing payment: $1,750
- Estimated home price range: $260,000 - $300,000
- Down payment needed: $39,000 - $45,000
$100,000 Annual Salary
- Maximum monthly housing payment: $2,333
- Estimated home price range: $350,000 - $400,000
- Down payment needed: $52,500 - $60,000
$150,000 Annual Salary
- Maximum monthly housing payment: $3,500
- Estimated home price range: $525,000 - $600,000
- Down payment needed: $78,750 - $90,000
$200,000 Annual Salary
- Maximum monthly housing payment: $4,667
- Estimated home price range: $700,000 - $800,000
- Down payment needed: $105,000 - $120,000
These ranges assume good credit (740+ FICO), minimal existing debt, and current interest rates. Your actual buying power may vary significantly based on these factors.
Debt-to-Income Ratio: The Make-or-Break Factor
Your debt-to-income ratio (DTI) is often more limiting than the 28% housing rule. Here's how different loan types handle DTI:
- Conventional loans: Typically max 43-45% DTI, though some allow up to 50% with strong credit
- FHA loans: Allow up to 57% DTI in some cases
- VA loans: No strict DTI limit, but most lenders cap around 41%
- Jumbo loans: Usually stricter, maxing at 43% DTI
To calculate your DTI, add up all monthly debt payments (credit cards, car loans, student loans, etc.) plus your proposed housing payment, then divide by gross monthly income.
Beyond the Basic Rules: What Lenders Really Consider
Credit Score Impact
Your credit score dramatically affects both qualification and rates:
- 760+ FICO: Best rates, maximum flexibility on DTI
- 680-759 FICO: Good rates, standard DTI limits
- 620-679 FICO: Higher rates, stricter DTI requirements
- Below 620 FICO: Limited to FHA or VA loans
Down Payment Considerations
While 20% down eliminates mortgage insurance, many successful buyers use less:
- Conventional loans: As low as 3% down for first-time buyers
- FHA loans: 3.5% down payment minimum
- VA loans: 0% down for eligible veterans
- USDA loans: 0% down in eligible rural areas
Seattle-Specific Considerations
The Seattle housing market presents unique challenges that affect affordability:
- Higher property taxes than national average
- HOA fees common in condos and townhomes
- Competitive market may require larger down payments
- Tech industry stock compensation can complicate income calculations
Common Affordability Mistakes to Avoid
In my experience, these are the most costly mistakes Seattle homebuyers make:
- Ignoring total monthly costs: Property taxes, insurance, HOA fees, and maintenance add significantly to your payment
- Maxing out your budget: Leave room for rate increases if considering an ARM, plus unexpected expenses
- Forgetting closing costs: Budget 2-3% of purchase price for closing costs and moving expenses
- Not getting pre-approved: Pre-qualification isn't enough in competitive markets
Use Online Calculators Wisely
Online affordability calculators provide good starting points, but they can't replace professional analysis. Most calculators don't account for:
- Local tax rates and insurance costs
- Your specific credit profile
- Complex income situations (self-employment, bonuses, RSUs)
- Available loan programs and down payment assistance
Getting Your Exact Buying Power
The only way to know your true home affordability is through professional pre-approval. During this process, I'll analyze your complete financial picture, including income documentation, credit report, assets, and debts to determine your exact loan amount and monthly payment.
This analysis becomes especially important for Seattle buyers dealing with stock options, irregular income, or unique financial situations common in our tech-heavy economy.
