Mortgage Rates
How Mortgage Rates Are Actually Set
What actually drives mortgage pricing, why your rate differs from the advertised rate, and which parts of the equation you control.
Updated 2026-08-24| Applies to: Anyone shopping for a purchase or refinance rate.
The short answer
Mortgage rates track the bond market rather than the Federal Reserve directly. Your specific rate then adjusts for credit score, loan to value, occupancy, property type, loan purpose and points, which is why quoted averages rarely match a real offer.
Two people can apply on the same day, with the same lender, and receive different rates. Nothing shady is happening; pricing is built from layers.
The base layer
Most mortgages are packaged into mortgage backed securities. What investors will pay for those securities sets the baseline. That is why rates react to inflation data, employment reports and bond yields rather than moving lockstep with Fed announcements.
The adjustment layer
| Factor | Direction |
|---|---|
| Higher credit score | Better pricing |
| Larger down payment | Usually better pricing |
| Investment property | Higher rate than a primary residence |
| Two to four unit property | Typically an adjustment upward |
| Cash out refinance | Higher than a rate and term refinance |
| Discount points paid | Lower rate for an upfront cost |
What you control
- Credit profile before you apply
- Down payment size and the resulting loan to value
- Whether you pay points or take a lender credit
- Loan term and product structure
- Timing of your rate lock
Comparing offers honestly
A rate is only comparable next to its costs. Ask every lender for the same loan amount, the same lock period and a written Loan Estimate on the same day. Compare the rate, the points and the total lender charges together.
Rates change constantly and vary by borrower and program. Nothing here is a rate quote or a commitment to lend.
Common mistakes to avoid
- Comparing a rate quoted with points against one quoted without
- Assuming a Fed rate cut lowers mortgage rates the same day
- Shopping quotes across different days and calling it a comparison
