Quick Answer
The general guideline: Your total housing costs (mortgage + property taxes + insurance + HOA) should not exceed 28% of your gross monthly income, and your total debt payments should not exceed 36%. This is called the 28/36 rule and is one of the most widely used affordability frameworks.
| Gross Annual Income | Max Monthly Housing (28%) | Approx. Home Price* |
|---|---|---|
| $60,000 | $1,400 | $195,000 - $225,000 |
| $80,000 | $1,867 | $260,000 - $300,000 |
| $100,000 | $2,333 | $325,000 - $375,000 |
| $120,000 | $2,800 | $390,000 - $450,000 |
| $150,000 | $3,500 | $490,000 - $560,000 |
*Assumes 30-year fixed at 7%, 20% down, no other significant debt. Estimates are approximate.
Key insight: What you qualify for and what you can comfortably afford are often very different numbers. Lenders may approve you for up to 43% DTI. This guide helps you determine YOUR comfortable number.

Key Takeaways
- The 28/36 rule says total housing costs should not exceed 28% of gross income and total debt should not exceed 36% -- this is your starting framework
- What lenders approve (up to 43-50% DTI) is often significantly more than what is financially comfortable -- being "house poor" leaves no room for savings or emergencies
- Hidden homeownership costs add 30-50% to your mortgage payment: property taxes, insurance, maintenance, PMI, and HOA fees
- The most financially sound approach targets 25% of gross income for total housing costs, leaving a buffer for unexpected expenses

The 28/36 Rule Explained
The 28/36 rule is one of the most widely used affordability guidelines in mortgage lending. It consists of two ratios that measure how much of your income goes toward debt:
Front-End Ratio (28%)
Your total monthly housing costs divided by your gross monthly income. Housing costs include: principal + interest + property taxes + homeowners insurance + PMI (if applicable) + HOA fees. This is sometimes called the "housing ratio" or "front-end DTI."
Back-End Ratio (36%)
Your total monthly debt payments (housing + all other debt minimums) divided by your gross monthly income. Other debts include: car payments, student loans, credit card minimums, personal loans, alimony, and child support. For a deeper explanation of how DTI ratios work, see our complete guide.
Worked Example: $100,000 Household Income
Gross monthly income: $8,333
- 28% front-end = $2,333/month maximum housing costs
- 36% back-end = $3,000/month maximum total debt
- If you have $500/month in car and student loan payments: $3,000 - $500 = $2,500 available for housing
In this example, the back-end ratio is less restrictive than the front-end ratio. But if your other debts were $800/month, back-end housing capacity drops to $2,200 -- lower than the front-end limit, making it the binding constraint.
Where the 28/36 rule came from: The 28% and 36% ratios are long-standing benchmarks from conventional mortgage underwriting. They remain widely used by lenders and financial advisors today as a conservative starting point, even though Fannie Mae's automated underwriting can now approve total debt ratios up to 50%.
Modern lending reality: Many lenders now approve loans up to 43% DTI or even 50%+ for some programs. (The old 43% cap in the federal Qualified Mortgage rule was replaced by a price-based test, mandatory since October 2022.) Just because you qualify does NOT mean it is comfortable. Understanding your full PITI payment is essential before committing.
What Lenders Allow vs. What Is Comfortable
There is a significant gap between what a lender will approve and what financial advisors recommend as comfortable. This gap is where many homebuyers run into trouble.
| Income $100K | 25% Housing (Conservative) | 28% Housing (28/36 Rule) | 43% Total Debt (Lender Max)* |
|---|---|---|---|
| Monthly housing budget | $2,083 | $2,333 | $3,583 |
| Approx. home price | $290K - $330K | $325K - $375K | $500K - $575K |
| Monthly breathing room | High | Moderate | Very low |
*Assumes no other monthly debt, so the full 43% goes to housing. Car, student loan and credit card payments come out of that 43% first: with Section 2's $500/month of other debt, the housing budget is $3,083.
What Does "House Poor" Mean?
"House poor" describes a situation where you spend so much on housing that you cannot save for retirement, build an emergency fund, or enjoy your lifestyle. It happens when buyers stretch to the maximum their lender approves without accounting for the full picture of homeownership costs.
Warning Signs You Are Buying Too Much House
- You cannot save 15%+ for retirement while paying the mortgage
- You would have less than 3 months of emergency fund after closing
- You would be in financial crisis if one income earner lost their job
- You are counting on future raises to make payments comfortable
Recommendation: Target 25% of gross income for total housing costs as a conservative, sustainable target. This is especially important for first-time homebuyers who may not yet understand the full scope of homeownership expenses.
The True Cost of Homeownership Beyond the Mortgage
Your mortgage payment is only one piece of the homeownership puzzle. These additional costs can add 30-50% to your monthly housing expense, and they are a common surprise for new homeowners.
Property Taxes
Property taxes vary dramatically by state, ranging from under 0.3% (Hawaii) to about 1.9% (New Jersey and Illinois) of home value, according to the Tax Foundation's 2026 edition (2024 Census data). The typical state rate is roughly 1%; the tables in this guide assume 1.1%.
- On a $350,000 home: $3,850/year (at 1.1%) to about $6,650/year (at New Jersey's roughly 1.9%)
- Property taxes are often the largest "hidden" cost that buyers underestimate
- Taxes can increase annually with reassessment -- budget for increases rather than assuming today's bill stays fixed
Our Mortgage Affordability Calculator includes a property tax rate field to give you a more realistic estimate for your specific area.
Homeowners Insurance
- National averages run about $2,200 - $2,900/year for $300,000 of dwelling coverage, depending on the survey, and are much higher in disaster-prone areas (for example, Florida)
- Required by all mortgage lenders
- Does NOT cover flooding -- separate flood insurance ($500 - $3,000+/year) is required in many areas
- Costs increase with home value, location risk, and claim history
Maintenance and Repairs
The "1% rule": Budget approximately 1% of your home's value per year for maintenance. On a $350,000 home, that is approximately $3,500/year ($292/month). Some financial advisors recommend 1.5-2% for older homes built before 1970.
Major expenses to plan for:
- Roof replacement: $8,000 - $15,000 every 20-30 years
- HVAC replacement: $5,000 - $12,000 every 15-20 years
- Water heater: $1,000 - $3,000 every 10-12 years
- Appliance replacement, exterior painting, plumbing, electrical
This cost does not exist for renters -- it is a significant line item that buyers frequently forget. Consider our Rent vs. Buy Decision Guide to compare the full cost picture.
PMI (Private Mortgage Insurance)
- Required if down payment is less than 20%
- Cost: roughly 0.46% - 1.5% of loan amount per year with a low down payment (Urban Institute data reported by Experian, May 2026)
- On a $300,000 loan: about $1,380 - $4,500/year ($115 - $375/month)
- Can be removed once you reach 20% equity (some loans require 22%)
For a detailed breakdown of how PMI works and strategies to eliminate it, see our Understanding PMI guide. If a lower down payment is your only option, explore FHA loan requirements which have different insurance structures.
HOA Fees
- Typical: the median fee among households that pay one was $135/month in 2024 (Census Bureau); among homes listed for sale in 2025, medians were about $420/month for condos and $63/month for single-family homes (Realtor.com); $0 for non-HOA properties
- Can increase annually -- median fees rose roughly 26%-29% from 2019 to 2025 (Realtor.com)
- Special assessments for major repairs can add thousands of dollars as one-time charges
- Important: HOA fees are included in your DTI calculation by lenders
Do not forget about closing costs either -- typically 2-5% of the home price, paid upfront at purchase.
Affordability by Salary: Detailed Breakdown
The table below shows the true monthly cost of homeownership at different income levels, including all the hidden costs most buyers overlook. Home price targets follow the standard 28% housing guideline (the top of Section 3's 28/36 column); once property taxes, insurance, and maintenance are added, the % OF GROSS column lands at roughly 31-33% -- which is exactly why many advisors recommend the more conservative 25% target instead.
| Annual Income | Home Price Target | Mortgage P&I | Property Tax | Insurance | Maintenance | Total Monthly | % of Gross |
|---|---|---|---|---|---|---|---|
| $60,000 | $200,000 | $1,064 | $183 | $150 | $167 | $1,564 | 31% |
| $80,000 | $280,000 | $1,490 | $257 | $188 | $233 | $2,168 | 33% |
| $100,000 | $350,000 | $1,863 | $321 | $208 | $292 | $2,684 | 32% |
| $120,000 | $425,000 | $2,262 | $390 | $240 | $354 | $3,246 | 32% |
| $150,000 | $525,000 | $2,794 | $481 | $275 | $438 | $3,988 | 32% |
Assumptions: 30-year fixed at 7%, 20% down payment, 1.1% property tax rate, average insurance, 1% annual maintenance. Home price targets are lower than lender maximums. Figures are approximate.
Notice that even with conservative home price targets, total monthly costs run approximately 31-33% of gross income when you include property taxes, insurance, and maintenance. This is why the raw mortgage payment alone gives an incomplete picture. For a salary-specific deep dive, see our guide on how much house you can afford on $80K.
Remember that gross income is not the same as take-home pay. Your actual available cash after federal and state taxes, Social Security, and Medicare will be significantly lower -- making the true housing burden feel larger than the percentage suggests.
The Mortgage P&I column above uses the same amortization formula as our mortgage calculator methodology page -- our affordability calculator has no separate methodology page since it runs that formula in reverse, from your income and debts back to a home price.
5 Factors Calculators Do Not Capture
Even the most comprehensive affordability calculator cannot account for these real-world factors that determine whether you love or regret your home purchase:
1. Lifestyle Impact
A larger mortgage means smaller vacations, delayed car replacement, less dining out, and fewer discretionary purchases. Consider honestly: what lifestyle changes are you willing to make? Some people happily sacrifice for homeownership while others become resentful when they realize the tradeoffs.
2. Career Stability
If your income is variable (commission, freelance, seasonal work, or startup equity), use your lowest expected annual income as the basis for affordability, not your best year. A mortgage payment that is comfortable on $120K becomes a crisis on $80K.
3. Future Life Changes
Planning to have children? Childcare costs $10,000 - $20,000+ per year in many areas. Planning to change careers or go back to school? These events reduce your future income available for housing. Buy based on your current financial reality, not optimistic assumptions about the future.
4. Commute Costs
A cheaper house in a distant suburb may cost more after factoring in gas, car wear, tolls, and time. A $30/day commute adds $7,800/year to your effective housing cost. A home that is $50,000 less expensive but adds an hour to your daily commute may not be the bargain it appears.
5. Opportunity Cost of the Down Payment
A $70,000 down payment invested in the stock market at a 7% average return would grow to approximately $137,700 in 10 years. Homeownership offers appreciation too, but the opportunity cost is real. This does not mean you should not buy -- it means the financial comparison is more nuanced than "mortgage payment vs. rent."
Tax Considerations
Homeownership offers potential tax benefits through the mortgage interest deduction. However, with the larger standard deduction, many homeowners no longer benefit from itemizing. Factor this into your overall affordability calculation.
Frequently Asked Questions
Using the standard 28% housing guideline with no other debt, you can afford approximately a $325,000 - $375,000 home (30-year fixed at 7%, 20% down). Under the more conservative 25% target, aim for roughly $290,000 - $330,000. Use our Mortgage Affordability Calculator with your specific numbers for a personalized estimate. For the full step-by-step method, see our guide How Much House Can I Afford?
The 28/36 rule says your total housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of gross monthly income, and your total debt payments should not exceed 36%. It is a long-standing conventional lending benchmark, though today's underwriting systems can approve higher ratios. Some financial advisors recommend the more conservative 25% target.
No. Lenders approve based on your ability to make the minimum payment, not on your overall financial health. Buying at the maximum creates financial fragility: no room for emergencies, retirement savings, or lifestyle. One approach is to target well below your maximum approval, for example 75-80% of it.
Budget 1-2% of your home's value per year. For a $350,000 home, that is $3,500 - $7,000/year ($292 - $583/month). Newer homes (under 10 years) may need less; older homes may need more. This is money renters do not have to budget for.
Yes, significantly. A larger down payment means a smaller loan (lower monthly payment), no PMI if 20%+ down, and potentially a better interest rate. However, depleting your savings for a larger down payment creates risk. Keep at least 3-6 months emergency fund AFTER closing.
Property taxes can dramatically affect affordability depending on your state. On a $400,000 home, property taxes at typical state rates range from about $1,200/year (Hawaii, under 0.3%) to about $7,600/year (New Jersey, about 1.9%). That is a difference of roughly $530/month in housing costs from property taxes alone. Always check the specific tax rate for the area where you plan to buy.
If both spouses will be on the mortgage and plan to continue working, yes. However, consider: what if one income stops (job loss, childcare, health issue)? Some advisors recommend qualifying on one income and using the second income as a financial buffer for savings and emergencies.
No. Renting can be financially superior in high-cost markets, for short-term stays (under 5 years), or when the price-to-rent ratio is unfavorable. Because of closing costs and transaction fees, buying often takes several years to break even with renting. See our Rent vs. Buy Decision Guide for a detailed comparison.
Key Takeaways
- The 28/36 rule is your starting framework: keep total housing costs under 28% of gross income and total debt under 36% -- but some advisors recommend the more conservative 25% target
- What you qualify for (43-50% DTI) is often far more than what is comfortable -- buying at your maximum approval creates "house poor" financial fragility
- Budget 30-50% beyond your mortgage payment for property taxes, insurance, maintenance, PMI, and HOA fees -- these hidden costs are a common surprise for new homeowners
- Consider lifestyle, career stability, future life changes, and commute costs -- factors that no calculator can capture but that determine whether you love or regret your home purchase
