Understanding Your Monthly Payment (PITI)

Many buyers focus only on the loan principal and interest, but your total monthly housing cost is often 25-35% higher once taxes and insurance are added. Whether you pay these through an 'Escrow' account or directly, they are critical to your budget. Here is the breakdown:

  • Principal: The portion that actually pays down your debt and builds equity.
  • Interest: The fee you pay the bank. In the early years of a 30-year loan, this can be 70%+ of your payment.
  • Taxes (Property Tax): A fee paid to your local government, usually bundled into your monthly mortgage bill.
  • Insurance (Homeowners & PMI): Protection for your home. If you put down less than 20%, you will likely pay an extra fee called PMI (Private Mortgage Insurance).

The Strategic Decision: 30-Year vs. 15-Year

Scenario A: The "Cash Flow" Priority

  • The Setup: Buy a $375,000 home with 20% down ($75,000), resulting in a $300,000 Loan at 6.5% for 30 Years.
  • Monthly P&I: ~$1,896.
  • Total Interest Paid: ~$382,000.
  • The Verdict: Lower monthly payments make the home more affordable month-to-month, but you pay more than double the loan amount over time.

Scenario B: The "Wealth Building" Priority

  • The Setup: Same home ($375k) and down payment ($75k), but financing the $300,000 Loan at 6.0% for 15 Years.
  • Monthly P&I: ~$2,531.
  • Total Interest Paid: ~$155,000.
  • The Verdict: The payment is ~$635 higher per month, but you own the home in half the time and save over $220,000 in interest.

Home Financing Essentials

Q: How much down payment do I really need?

A: The "20% rule" is a myth for buying, but real for saving money. You can buy a home with as little as 3% to 3.5% down (Conventional or FHA), but doing so triggers PMI (Private Mortgage Insurance), which typically costs 0.5%–1.5% of your loan annually until you reach 20% equity.

Q: What is "Escrow"?

A: An Escrow account is a forced savings account managed by your lender. Instead of paying a huge property tax and insurance bill once a year, you pay 1/12th of the estimated total every month with your mortgage. The lender holds this money and pays the bills for you when they are due.

Q: Does making extra principal payments really help?

A: Yes, significantly. Because interest is calculated on your *current* balance, every extra $100 you pay reduces the balance immediately, lowering the interest charged next month. Making just one extra payment per year can shave 4 to 6 years off a 30-year mortgage, depending on your interest rate.

Q: How much house can I afford?

A: Lenders look at your Debt-to-Income (DTI) ratio. While many will approve total debts up to 43% (or higher), the traditional 28/36 Rule is the gold standard for financial safety. Your housing costs (PITI) shouldn't exceed 28% of your gross monthly income, and your total debt (housing + cars + student loans) shouldn't exceed 36%. Use these ratios to set a safe budget before browsing listings.

Q: What are "Closing Costs" and how much are they?

A: In addition to your down payment, you must pay closing costs—fees for the appraisal, title search, and loan origination. Expect to pay 2% to 5% of the purchase price. For a $500,000 home, that is an extra $10,000 to $25,000 due on signing day.

Q: Should I pay "Points" to lower my interest rate?

A: It depends on how long you stay. Buying "Discount Points" means paying 1% of the loan amount upfront to lower your rate by roughly 0.25%. This is usually a smart move only if you plan to keep the mortgage for more than 6-7 years (the "break-even point"). If you might move or refinance sooner, skip the points.
