Complete Guide: How Much House Can I Afford?
Determining how much house you can afford is one of the most important financial decisions you’ll make. This comprehensive guide will walk you through all the factors that influence your home buying power, from income and debts to interest rates and down payments.
Understanding the 28/36 Rule
The 28/36 rule is a traditional guideline used by lenders to assess home affordability:
- 28%: No more than 28% of your gross monthly income should go toward housing expenses (mortgage principal, interest, property taxes, and insurance)
- 36%: No more than 36% of your gross monthly income should go toward all debt payments (housing + credit cards, car loans, student loans, etc.)
| Income Level | 28% Rule Max Payment | 36% Rule Max Payment | Estimated Home Price (30yr @ 6.5%) |
|---|---|---|---|
| $50,000 | $1,167 | $1,500 | $185,000 |
| $75,000 | $1,750 | $2,250 | $278,000 |
| $100,000 | $2,333 | $3,000 | $370,000 |
| $150,000 | $3,500 | $4,500 | $555,000 |
Key Factors That Determine Affordability
1. Your Income
Lenders primarily consider your gross monthly income (before taxes) when determining how much you can borrow. This includes:
- Salary/wages
- Bonuses and commissions
- Alimony/child support (if consistent)
- Rental income (if you own other properties)
- Social Security or pension income
2. Your Debts
Existing debts reduce your borrowing power because lenders consider your debt-to-income ratio (DTI). Common debts include:
- Credit card minimum payments
- Car loans
- Student loans
- Personal loans
- Alimony/child support payments
3. Down Payment
The size of your down payment significantly impacts:
- Loan amount: Larger down payment = smaller loan
- Interest costs: Smaller loan = less interest paid over time
- Mortgage insurance: 20%+ down avoids PMI (Private Mortgage Insurance)
- Interest rate: Larger down payments often qualify for better rates
| Down Payment % | Loan Amount ($300k home) | Monthly PMI Cost | Interest Savings (30yr @ 6.5%) |
|---|---|---|---|
| 3% | $291,000 | $150-$200 | $0 (baseline) |
| 10% | $270,000 | $80-$120 | $35,000 |
| 20% | $240,000 | $0 | $70,000 |
| 30% | $210,000 | $0 | $105,000 |
4. Interest Rates
Mortgage interest rates have a dramatic impact on affordability. Even small differences add up over 30 years:
- A 1% rate increase on a $300,000 loan adds ~$200/month or $72,000 over 30 years
- Rates fluctuate based on economic conditions, your credit score, and loan type
- Current average rates (as of 2023) range from 6-8% for 30-year fixed mortgages
5. Loan Term
The length of your mortgage affects both your monthly payment and total interest paid:
- 15-year mortgage: Higher monthly payments but significantly less interest
- 30-year mortgage: Lower monthly payments but more interest over time
- ARM (Adjustable Rate Mortgage): Lower initial rates that can increase later
Additional Costs to Consider
Many first-time buyers overlook these significant expenses:
- Closing Costs (2-5% of home price): Appraisal, inspection, title insurance, etc.
- Property Taxes: Vary by location (0.5% to 2.5% of home value annually)
- Home Insurance: Typically $1,000-$3,000/year depending on location and coverage
- Maintenance (1-2% of home value/year): Repairs, upgrades, and unexpected issues
- HOA Fees: Can add $200-$800/month for condos or planned communities
- Moving Costs: Professional movers or truck rentals
- Utilities: Often higher than renting (especially for larger homes)
How to Improve Your Affordability
If the numbers aren’t working in your favor, consider these strategies:
- Increase your income: Ask for a raise, take on a side hustle, or consider a higher-paying job
- Pay down debt: Reduce credit card balances and eliminate smaller loans
- Save for a larger down payment: Even 5% more can significantly improve your terms
- Improve your credit score: Aim for 740+ for the best interest rates
- Consider first-time homebuyer programs: Many offer down payment assistance or lower rates
- Look at less expensive areas: Expand your search to more affordable neighborhoods
- Get pre-approved: Shows sellers you’re serious and helps you understand your budget
Common Mistakes to Avoid
- Maxing out your budget: Leave room for unexpected expenses and lifestyle changes
- Ignoring the total cost: Focus on the monthly payment AND the total interest paid
- Skipping the inspection: Always get a professional home inspection
- Depleting your savings: Keep 3-6 months of expenses in reserve
- Forgetting about resale: Consider how easy it will be to sell the home later
- Not shopping around for lenders: Compare rates from at least 3 different lenders
Government Resources and Programs
Several government programs can help make homeownership more affordable:
- FHA Loans: Require as little as 3.5% down with more flexible credit requirements. Learn more at the U.S. Department of Housing and Urban Development.
- VA Loans: Offer 0% down payments for eligible veterans and service members. Details at the U.S. Department of Veterans Affairs.
- USDA Loans: Provide 100% financing for rural and suburban homebuyers. Information available at the USDA Rural Development.
- State and Local Programs: Many states offer first-time homebuyer grants and low-interest loans. Check with your state’s housing finance agency.

Frequently Asked Questions
How much house can I afford on a $70,000 salary?
With a $70,000 salary, no other debts, and a 20% down payment, you could typically afford a home in the $250,000-$300,000 range with a 30-year mortgage at current interest rates. Your maximum monthly housing payment would be about $1,633 (28% of your gross income).
Is it better to put 20% down or pay PMI?
This depends on your situation. Putting 20% down avoids PMI (typically $50-$200/month) and gets you better interest rates. However, if 20% would deplete your savings, paying PMI might be worth it to keep emergency funds available. Run the numbers both ways to see which option saves you more in the long run.
How does my credit score affect how much house I can afford?
Your credit score directly impacts your interest rate, which affects your monthly payment and total loan amount. For example, on a $300,000 loan:
- 760+ credit score: ~6.5% interest rate ($1,896/month)
- 680-719 credit score: ~7.25% interest rate ($2,041/month)
- 620-679 credit score: ~8.5% interest rate ($2,308/month)
A lower score could reduce your purchasing power by $50,000 or more.
Should I get a 15-year or 30-year mortgage?
A 15-year mortgage saves you tens of thousands in interest but has higher monthly payments. A 30-year mortgage gives you more flexibility and lower payments. Many financial advisors recommend getting a 30-year mortgage but making extra payments when possible – this gives you the flexibility to pay more when you can while keeping the option to pay less during tougher financial times.
How much should I spend on a house?
While lenders may approve you for a loan up to 43-50% DTI, most financial experts recommend:
- Spending no more than 28% of your gross income on housing
- Keeping your total debt payments below 36% of your gross income
- Leaving room in your budget for savings (15-20% of income)
- Considering your other financial goals (retirement, travel, etc.)
Remember that just because you can afford a certain payment doesn’t mean you should spend that much.
