Home Glossary — Key Terms Explained
- APR (Annual Percentage Rate)
- The true annual cost of borrowing, including interest rate plus lender fees and points, expressed as a percentage. APR is always higher than the note rate and enables apples-to-apples loan comparison.
- LTV (Loan-to-Value Ratio)
- The ratio of your mortgage balance to the home's appraised value. LTV = Loan Amount ÷ Home Value × 100. Below 80% LTV eliminates PMI; below 60% typically earns the best rates.
- DTI (Debt-to-Income Ratio)
- Total monthly debt payments divided by gross monthly income. Most lenders cap DTI at 43–45%. A lower DTI improves loan approval odds and often earns a better rate.
- PITI (Principal, Interest, Taxes, Insurance)
- The four components of a complete monthly mortgage payment. Lenders use total PITI when calculating DTI.
- PMI (Private Mortgage Insurance)
- Insurance required on conventional loans with less than 20% down. PMI typically costs 0.3–1.5% of the loan balance annually and is cancellable once LTV reaches 80%.
- Escrow
- A lender-held account funded by a portion of each monthly payment to cover property taxes and homeowners insurance when they come due. Most lenders require escrow for loans with LTV above 80%.
- Amortisation
- The process of paying off a loan through scheduled payments that cover both interest and principal. Early in the amortisation schedule, most of each payment is interest; later payments are mostly principal.
- Points (Discount Points)
- Upfront fees paid to a lender to reduce the interest rate. One point = 1% of the loan amount. Paying points makes sense when you plan to stay in the home long enough to recoup the cost through lower monthly payments.
- Rate Lock
- A lender's guarantee that your quoted mortgage rate will remain fixed for a set period (typically 30–60 days) while your loan is in underwriting. Rate locks protect you from rate increases before closing.
- Closing Costs
- Fees and expenses paid at settlement, separate from the down payment. Typically 2–5% of the loan amount. Common closing costs include appraisal fees, title insurance, origination fees, and prepaid taxes and insurance.
Frequently Asked Questions
What is the monthly payment on a $400,000 mortgage?
At a 7.5% fixed rate with a 30-year term and 20% down, a $400,000 home requires a $320,000 mortgage. Monthly principal and interest = approximately $2,237. Adding property taxes ($400/month) and homeowners insurance ($150/month) brings the total monthly payment to approximately $2,787. Use a mortgage payment calculator with your actual rate and local tax estimates for an accurate figure.
How much mortgage can I afford on $80,000 salary?
Using the standard guideline that total housing costs (PITI) should not exceed 28% of gross monthly income: $80,000 ÷ 12 = $6,667/month gross income × 28% = $1,867/month for housing. At 7.5% rate, 30-year term, and $300/month for taxes/insurance, this supports a mortgage of approximately $230,000–$260,000 depending on debt load.

What is a good interest rate for a mortgage in 2026?
30-year fixed mortgage rates in 2026 have been in the 6.5%–8.0% range depending on credit score, loan size, and market conditions. Borrowers with 760+ credit scores, 20% down payment, and DTI below 36% qualify for the lowest available rates. Compare at least 3–5 lender quotes, including local credit unions — rates can vary 0.25%–0.5% for the same borrower across lenders.
How does refinancing affect my monthly payment?
Refinancing replaces your current mortgage with a new loan at a different rate or term. Refinancing to a lower rate reduces your monthly payment. Refinancing to a shorter term (e.g., 30yr to 15yr) increases the monthly payment but reduces total interest dramatically. The break-even calculation — closing costs ÷ monthly savings — tells you how many months until refinancing pays off. Use our mortgage refinance calculator to model your specific scenario.
What is PMI and when can I remove it?
Private Mortgage Insurance (PMI) is required by lenders when you put less than 20% down on a conventional loan. It protects the lender, not you, and typically costs 0.3–1.5% of the loan balance per year. Under the Homeowners Protection Act, lenders must cancel PMI automatically when your LTV reaches 78% (based on original value). You can request cancellation at 80% LTV. An appraisal may be needed if home values have increased significantly.
