How Much House Can You Afford?

Lenders use standardized ratios to determine maximum loan amounts; understanding these before you shop prevents falling in love with homes outside your financial reality.

🛡️ The 28/36 Rule: The Foundation of Mortgage Underwriting

Standard conventional mortgage guidelines follow the 28/36 Rule (also called the front-end/back-end ratio):

Front-End Ratio (28%) Your total monthly housing payment (PITI) should not exceed 28% of gross monthly income.

• Principal (loan repayment)
• Interest
• Taxes (property tax, typically escrowed)
• Insurance (homeowner's insurance + PMI if applicable)

> Example: $100,000 gross annual income = $8,333/month → Maximum PITI: $2,333/month

Back-End Ratio (36%) Total monthly debt payments (PITI + all other debts) should not exceed 36% of gross monthly income.

• Includes: car loans, student loans, credit card minimums, personal loans, child support

> Same example: Maximum total debt: $3,000/month** → If car loan = $450, student loan = $350 → Maximum PITI: $3,000 − $800 = **$2,200/month

📊 DTI Limits by Loan Type

Different loan programs accept different debt-to-income ratios:

| Loan Type | Max Front-End DTI | Max Back-End DTI | Down Payment Minimum | |---|---|---|---| | Conventional (Fannie/Freddie) | 28% | 36–43% | 3–20% | | FHA Loan | 31% | 43–50%* | 3.5% | | VA Loan (Veterans) | No limit | 41%* | 0% | | USDA Loan (Rural) | 29% | 41% | 0% | | Jumbo Loan | 28% | 36–43% | 10–20% |

*Automated underwriting may approve higher DTIs with compensating factors (large cash reserves, high credit score).

💰 How Interest Rates Change Your Buying Power

Interest rate changes have a dramatic impact on affordability. At the same $2,000/month PITI budget (before taxes and insurance):

| Rate | Maximum Loan Amount (30-yr) | Home Price (20% down) | |---|---|---| | 5.0% | $372,600 | ~$466,000 | | 6.0% | $333,600 | ~$417,000 | | 6.5% | $316,400 | ~$396,000 | | 7.0% | $300,600 | ~$376,000 | | 7.5% | $285,900 | ~$357,000 | | 8.0% | $272,200 | ~$340,000 |

A 1% rate increase reduces buying power by approximately 10–11%.

🏦 Private Mortgage Insurance (PMI)

If your down payment is less than 20%, conventional lenders require PMI—insurance that protects the lender (not you) if you default. PMI typically costs 0.5–1.5% of the loan amount annually, added to your monthly payment.

• $400,000 loan at 1% PMI**: $4,000/year = **$333/month added to your payment
• PMI cancels automatically when your loan balance reaches 80% of original value
• You can request cancellation when you reach 80% LTV through appreciation or paydown
• FHA loans have MIP (Mortgage Insurance Premium) that lasts the loan's life unless you refinance

📈 Down Payment Strategies

| Down Payment | PMI Required | Impact | |---|---|---| | 3% (Conventional) | Yes | Lowest entry; highest monthly cost | | 3.5% (FHA) | Yes (MIP, permanent) | Flexible credit requirements | | 5–10% | Yes | Moderate PMI cost | | 20% | No | No PMI; best monthly payment | | 25%+ | No | May qualify for better rates |

Down payment assistance programs: Many state and local programs offer grants or forgivable loans for first-time buyers. Check your state's Housing Finance Agency (HFA) for available programs.

🔑 Beyond the Calculator: Pre-Approval

A mortgage pre-approval (not just pre-qualification) gives you a conditional commitment from a lender at a specific loan amount. It requires a hard credit pull and verification of income, assets, and employment. Pre-approval:

• Shows sellers you're a serious buyer
• Locks in a rate for 60–90 days (with a rate lock option)
• Identifies any credit issues before you're under contract

Typical pre-approval requirements:

• Pay stubs (last 30 days), W-2s (last 2 years)
• Bank/investment account statements (last 2–3 months)
• Tax returns (last 2 years, especially for self-employed)
• Photo ID
