Things to Know
Essential concepts for understanding your results
The 28% RuleHow is home affordability calculated?
Lenders cap housing costs at 28% of gross monthly income (front-end DTI). This includes mortgage principal, interest, property taxes, homeowners insurance, PMI, and HOA fees. The back-end DTI (all debts) should stay below 36-43%. Your maximum home price depends on this payment limit, current interest rates, down payment size, and local property tax rates. Higher down payments and lower rates increase your purchasing power significantly.
Beyond the PaymentWhat costs does the mortgage payment not cover?
The mortgage payment is typically 60-70% of total housing costs. Budget additionally for: maintenance (1-2% of home value/year), utilities ($150-350/month), furnishing (one-time $5,000-15,000), lawn care, and potential HOA fees. A $2,000 mortgage payment often means $2,800-3,200 in total monthly housing expense. Always calculate total cost, not just P&I, when determining what you can afford.
Down Payment EffectHow does down payment size affect affordability?
A larger down payment increases affordability three ways: lower loan amount (smaller payment), potentially better rate (lower LTV = less risk), and no PMI at 20%+ (saves $100-300/month). Going from 5% to 20% down on a $350,000 home reduces the monthly payment by $400-500 when including PMI elimination. The trade-off: a larger down payment means less cash for emergency fund, moving costs, and home repairs.
Interest Rate ImpactHow much does the interest rate affect what you can afford?
Each 0.5% rate change shifts affordability by approximately $20,000-25,000 in home price. At 6.0%: a $2,000/month budget supports ~$335,000. At 6.5%: ~$315,000. At 7.0%: ~$300,000. A 1% rate difference on a $300,000 loan changes the monthly payment by $170-190 and total interest by $60,000-70,000 over 30 years. Timing your purchase during lower-rate periods can save six figures over the loan's life.
The 28/36 Rule for a $40K Salary
How much house can I afford on a $40K salary? This home affordability calculator shows the maximum mortgage, monthly payment, and price range for a $40K income. See how much home you can buy on $40K a year, what mortgage payment fits a $40K salary, and how down payment and interest rates affect affordability on $40K annual income.
The 28/36 rule is the standard guideline lenders use to determine how much house you can afford. On a $40,000 annual salary ($3,333/month gross):
28% Rule (Housing): Your total monthly housing cost — including mortgage principal, interest, property taxes, and homeowners insurance (PITI) — should not exceed $933/month.
36% Rule (Total Debt): Your total monthly debt payments — housing plus car loans, student loans, credit cards, and other debts — should not exceed $1,200/month.
This means if you have $320/month in existing debts, your maximum housing payment drops to $880/month.

Down Payment Options on $40K
For a $160,000 home (4x your salary):
20% down ($32,000): No PMI required. Lowest monthly payment. Best long-term option if you have the savings.
10% down ($16,000): Requires PMI (~$100-200/month extra). Good middle ground.
3.5% FHA ($5,600): Lowest upfront cost. Requires mortgage insurance for the life of the loan. Good for first-time buyers with limited savings.

Down Payment Scenarios for a $160,000 Home

| Down payment | Cash needed | Loan amount | Monthly P&I | PMI? |
|---|---|---|---|---|
| 3.5% (FHA) | $5,600 | $154,400 | $975 | Yes — MIP for life of loan |

| 20% | $32,000 | $128,000 | $809 | No PMI |
The difference between 3.5% and 20% down is $26,400 in upfront cash but saves approximately $286/month (lower payment + no PMI). Explore your options with our FHA vs conventional comparison and down payment calculator.

How Existing Debt Affects Your Home Budget
The 36% total debt rule means your combined housing + debt payments cannot exceed $1,200/month on a $40K salary. Every dollar of existing debt directly reduces how much house you can afford:
| Existing monthly debt | Max housing payment | Approx max home price | Reduction from $0 debt |
|---|---|---|---|
| $0 (no debt) | $933 | $160,000 | — |
| $300 (car payment) | $633 | $108,553 | -$51,446 |
| $600 (car + student loans) | $333 | $57,106 | -$102,893 |
| $1,000 (car + loans + cards) | $0 | $0 | -$160,000 |
$600/month in existing debt reduces your home budget by approximately $102,893. Paying off a car loan before applying for a mortgage directly increases your purchasing power. Use our DTI calculator and debt payoff calculator to optimize your approach.
