Introduction: Why Most Buyers Get This Wrong
“How much house can I really afford?” is one of the most common — and most misunderstood — questions in real estate.
Many buyers rely on online calculators or what a bank pre-approves them for. That often leads to homes that feel affordable on paper but stressful in real life. Monthly payments creep up. Savings disappear. One unexpected expense throws everything off.
This guide solves that problem.
You’ll learn how to calculate a realistic home budget, not just a lender-approved one. We’ll break down income, debt, credit, hidden costs, and lifestyle factors so you can buy a home confidently — without becoming house poor.
How Much House Can I Afford Based on Income?
Your income is the starting point, but it’s not the full story.
Lenders typically use gross income (before taxes), while your real affordability depends on net income (what actually hits your bank account).
The 28/36 Rule Explained
This rule is still widely used in mortgage underwriting.
- 28% rule: No more than 28% of gross monthly income on housing
- 36% rule: No more than 36% on total debt (housing + other debts)
Example
If you earn $6,000 per month gross:
- Max housing payment: ~$1,680
- Max total debt: ~$2,160
That sounds reasonable until real life enters the picture.
Why the Rule Is Only a Starting Point
The 28/36 rule doesn’t account for:
- Childcare
- Medical expenses
- Variable income
- Lifestyle goals
- Emergency savings
A safer approach is building your budget backward from your actual monthly cash flow.
How Much Mortgage Can I Afford Without Being House Poor?
Being “house poor” means your home eats up too much of your income.
You can technically afford the payment, but you:
- Can’t save
- Can’t travel
- Feel stressed every month
Signs You’re Stretching Too Far
- You rely on bonuses or overtime to pay bills
- You have no emergency fund after closing
- You cut retirement contributions
- One repair would cause debt
A home should support your life, not limit it.
Monthly Housing Costs Most Buyers Forget
Your mortgage payment is not your full housing cost.
What to Include in Your True Monthly Payment
- Principal and interest
- Property taxes
- Homeowners insurance
- HOA fees
- Maintenance (1–2% of home value per year)
- Utilities (often higher than renting)
Example
A $400,000 home might look affordable at first glance:
| Cost Item | Monthly Amount |
|---|---|
| Mortgage | $1,950 |
| Taxes | $400 |
| Insurance | $150 |
| HOA | $200 |
| Maintenance | $400 |
| Total | $3,100 |
That’s a big difference from the mortgage alone.
How Credit Score Affects How Much House You Can Afford
Your credit score impacts:
- Interest rate
- Monthly payment
- Loan options
- Required down payment
Rate Differences Add Up Fast
A small rate change can cost tens of thousands over time.
Example on a $350,000 loan
- 6.25% rate: ~$2,155/month
- 7.25% rate: ~$2,388/month
That’s over $230 more every month.
Improving your credit before buying can increase affordability without increasing income.
How Much House Can I Afford With Student Loans or Debt?
Debt reduces how much lenders — and you — can comfortably afford.
Debt-to-Income Ratio (DTI)
DTI compares your monthly debt to your income.
Common debt includes:
- Student loans
- Car payments
- Credit cards
- Personal loans
Even if payments are small, they reduce flexibility.
Practical Tip
If you’re close to buying:
- Pay down revolving debt
- Avoid new loans
- Consider delaying a car purchase
Small changes can increase buying power.
How Much House Can I Afford as a First-Time Buyer?
First-time buyers often overestimate affordability.
Why?
- Rent doesn’t include maintenance
- Ownership costs are unfamiliar
- Emotional pressure leads to stretching
First-Time Buyer Budget Framework
Instead of asking “What’s the max?”, ask:
- What payment feels comfortable?
- Can I still save 10–15%?
- Can I handle repairs?
A modest first home often builds more wealth than an expensive one you struggle to keep.
How Much House Can I Afford With a $100k Salary?
This is one of the most searched questions online.
Example Breakdown
Assumptions:
- $100,000 annual income
- $8,333 gross monthly
- Minimal debt
- 20% down
Estimated comfortable housing range:
- Monthly payment: $2,000–$2,400
- Home price: ~$350,000–$450,000 (market dependent)
Location, taxes, and rates matter more than salary alone.
How Down Payment Changes What You Can Afford
Your down payment affects:
- Loan size
- Monthly payment
- Mortgage insurance
- Interest rate
Down Payment Comparison
| Down Payment | Loan Size | Monthly Cost |
|---|---|---|
| 3% | High | Higher |
| 10% | Medium | Lower |
| 20% | Lowest | Lowest |
A smaller down payment may get you in sooner, but increases long-term cost.
Rent vs Buy: How Much House Is Actually Smart?
Buying only makes sense if:
- You plan to stay long enough
- The payment fits your life
- You can handle maintenance
Rent Might Be Better If:
- Your income is unstable
- You plan to move soon
- You’re still paying off high-interest debt
Homeownership is a financial tool, not a requirement.
Step-by-Step: How to Calculate Your Real Home Budget
Step 1: Calculate Net Monthly Income
Use take-home pay, not gross.
Step 2: Subtract Fixed Expenses
Include:
- Debt payments
- Childcare
- Insurance
- Subscriptions
Step 3: Set Savings First
Emergency fund and retirement come before housing.
Step 4: Decide on a Comfortable Payment
What leaves breathing room?
Step 5: Work Backward to Home Price
Include taxes, insurance, and HOA.
This method reflects reality, not marketing.

Frequently Asked Questions

It depends on debt, location, taxes, and lifestyle. Salary alone isn’t enough.

Yes, if it limits savings or causes stress.
How much should I spend on housing each month?
Most buyers feel comfortable at 20–25% of net income.

Possibly, but affordability depends on payment, not price.
