Understanding PITI — Your Real Monthly Payment
Most people focus on principal and interest but forget the other two components:
- P — Principal: Reduces your loan balance. Starts small, grows over time.
- I — Interest: Lender's profit. Starts large (most of early payments), shrinks over time.
- T — Taxes: Property tax collected monthly, held in escrow. Typically $300-800/month.
- I — Insurance: Homeowners insurance + PMI if under 20% down. Typically $100-300/month.
On a $400,000 30-year mortgage at 6.7%, your principal and interest is $2,582/month. But add $450 property tax + $150 insurance = $3,182 total PITI. Always budget for the full PITI, not just P&I.
15-Year vs 30-Year Mortgage: The Numbers
This is the most important mortgage decision you'll make. Here's the math on a $350,000 loan:
| 30-Year at 6.7% | 15-Year at 6.1% | Difference |
|---|
| Monthly P&I | $2,260 | $2,975 | +$715/month |
| Total Interest Paid | $463,700 | $185,400 | Save $278,300 |
| Total Amount Paid | $813,700 | $535,400 | |
| Home Paid Off | Year 2056 | Year 2041 | 15 years earlier |
Rule of thumb: Choose 15-year if the monthly payment is under 25% of your take-home pay. Choose 30-year if you need the flexibility — you can always pay extra principal voluntarily, which achieves similar interest savings.
How Much House Can You Afford in 2026?
Use the 28/36 rule: Your monthly PITI should be below 28% of gross monthly income. Total debt payments (including car loans, student loans) should be below 36%.
| Annual Income | Max Monthly PITI (28%) | Affordable Home Price (approx) |
|---|
| $60,000 | $1,400 | ~$175,000 |
| $80,000 | $1,867 | ~$235,000 |
| $100,000 | $2,333 | ~$295,000 |
| $120,000 | $2,800 | ~$360,000 |
| $150,000 | $3,500 | ~$455,000 |
| $200,000 | $4,667 | ~$615,000 |
First-Time Buyer Programs in 2026
Most states offer first-time buyer assistance programs including down payment grants (1-5% of purchase price), closing cost assistance, reduced interest rates, and tax credits. Check HUD.gov and your state's housing finance agency for current programs. Many offer significant assistance that dramatically reduces the upfront cost of buying.
❓ Frequently Asked Questions
Q: What is the minimum down payment to buy a house in 2026?
Minimum down payments in 2026: VA loan 0% (veterans), USDA loan 0% (rural areas), FHA loan 3.5% (580+ credit score), Conventional loan 3% (some programs). However, putting less than 20% down requires PMI which adds $100-300+/month to your payment. Most buyers put 10-20% down to balance upfront cost and monthly payment.
Q: What credit score do I need to buy a house?
Minimum credit scores: FHA loans 580 (3.5% down) or 500 (10% down). Conventional loans 620 minimum, 740+ for best rates. VA loans 620 (varies by lender). The difference between a 620 and 760 score on a $350,000 mortgage can be 0.5-1% in interest rate — saving $100-200/month and $36,000-72,000 over 30 years.
Q: How much are closing costs when buying a home?
Closing costs typically run 2-5% of the loan amount. On a $350,000 home: $7,000-17,500. Common costs: loan origination fee (0.5-1%), appraisal ($300-600), title insurance ($1,000-2,000), property taxes (2-6 months prepaid), homeowners insurance (first year), inspection ($300-500). Ask your lender for a Loan Estimate within 3 days of application.
Q: Is it better to rent or buy in 2026?
At current prices and interest rates, renting is often cheaper short-term but buying builds equity long-term. Break-even is typically 4-7 years — if you plan to stay that long, buying usually wins financially. Key factors: local price-to-rent ratio, how long you'll stay, opportunity cost of down payment, and transaction costs of selling.
Q: How does paying extra principal affect my mortgage?
Every extra dollar paid toward principal reduces future interest. On a $350,000 30-year loan at 6.7%: paying $200/month extra saves $99,000 in interest and pays off 7 years early. Even $100/month extra saves $56,000 and 4.5 years. The earlier in the loan you make extra payments, the greater the impact.
