🏠 What is a Mortgage?
A mortgage is a loan specifically used to purchase real estate. The property serves as collateral for the loan. Mortgages typically have terms of 15, 20, or 30 years, with fixed or adjustable interest rates. Each monthly payment covers both principal and interest, gradually building equity in your home.
🧮 Mortgage Payment Formula
M = P × [r(1+r)^n] / [(1+r)^n - 1]
Where:
• P = Principal loan amount
• r = Monthly interest rate (Annual rate ÷ 12)
• n = Total number of payments (Years × 12)

❓ Frequently Asked Questions (FAQ)
What is the difference between fixed-rate and adjustable-rate mortgages?
Fixed-rate mortgages have the same interest rate for the entire loan term. Adjustable-rate mortgages (ARMs) have rates that change after an initial fixed period, which can go up or down based on market conditions.
What is PMI and when do I need it?
Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. It protects the lender if you default. Once you reach 20% equity, you can usually cancel PMI.
How does my credit score affect my mortgage rate?
Higher credit scores qualify for lower interest rates. A 740+ score typically gets the best rates, while scores below 620 may face higher rates or difficulty qualifying.
What are closing costs?
Closing costs are fees paid at closing, typically 2-5% of the loan amount. They include appraisal fees, title insurance, attorney fees, and loan origination fees.
Can I pay off my mortgage early?
Yes, most mortgages allow early payoff without penalties. Making extra payments toward principal can save thousands in interest and help you own your home sooner.
