What Is a Mortgage?
A mortgage is a loan used to purchase real estate. You borrow money from a lender and repay it over time with interest. Most mortgages are paid monthly and include:
- Principal (loan amount)
- Interest (cost of borrowing)
- Insurance (sometimes)
- Taxes (optional depending on calculation)
Financial institutions like Wells Fargo or Bank of America commonly offer mortgage loans with different interest rates and terms.
What Is PMI (Private Mortgage Insurance)?
Private Mortgage Insurance (PMI) is a fee charged when your down payment is less than 20% of the home’s price.
It protects the lender—not the borrower—in case of default.
Key Points About PMI:
- Usually required for low down payments
- Paid monthly as part of your mortgage
- Can be removed once equity reaches 20%
