APR vs interest rate on a San Diego mortgage
Quick answer: The interest rate (note rate) is what sizes your principal and interest payment. APR is a broader percentage that folds in certain prepaid finance charges so you can compare Loan Estimates. APR is usually higher than the note rate when those costs exist. This page explains the difference. It does not invent a rate or an APR.
People ask for "the rate" and mean three different things: note rate, APR, and payment. Mixing them leads to bad comparisons. Here is the clean split for a San Diego purchase or refinance.
Interest rate (note rate)
- What it is. The contract rate on the loan. It drives principal and interest.
- What it is not. It is not your full monthly housing payment. Taxes, insurance, HOA, and mortgage insurance sit outside the note rate. See HOA dues in PITI and debt-to-income ratio San Diego.
- Points and credits. Paying discount points or taking lender credits changes the note rate and cash at closing. See discount points vs lender credits.
APR (annual percentage rate)
- What it is. A disclosure percentage that includes the note rate plus certain prepaid finance charges (rules set by regulation, not by this page).
- Why it exists. So two Loan Estimates with different fees are easier to compare than note rate alone.
- Why it confuses people. APR is not the payment multiplier. You do not multiply loan amount by APR to get the monthly bill. Payment still starts from the note rate, then adds PITI pieces.
