The rate you see on a billboard, in an email blast, or quoted at the top of Bankrate is rarely the rate you’ll actually be offered. That’s not a marketing trick — it’s the way mortgage pricing fundamentally works.
Understanding the gap between advertised and actual is one of the most useful things a buyer or refinancer can know.
Pricing engines, in plain terms
Every lender uses a pricing engine — software that takes your specific loan scenario and outputs a rate. The inputs:
- Credit score (the single biggest factor)
- Loan-to-value ratio (how much you’re borrowing vs. the home’s value)
- Property type (primary, second home, investment)
- Loan purpose (purchase vs. refinance vs. cash-out)
- Loan amount (relative to the conforming limit)
- Occupancy (owner-occupied vs. investment)
- Lock period (30, 45, 60 days)
- Discount points (paying upfront to lower the rate)
The advertised rate is usually the best-case combination — perfect credit, 25% down, primary residence, owner-occupied, 30-day lock, with one or two points paid upfront.
If your scenario doesn’t match all of those, your rate is different. Sometimes a little. Sometimes meaningfully.
The “rate sheet” reality
Lenders publish daily rate sheets that look like a grid: rate on one axis, points on the other. A single loan scenario might show as:
- 6.875% with -0.5 points (you get a credit at closing)
- 6.625% at par (no credit, no charge)
- 6.375% with 1.0 points (you pay $X up front for the lower rate)
All three are the same loan, just priced differently. The “headline” rate at any lender is usually the par rate for the cleanest possible scenario. Yours might be higher because of your scenario, lower because you’re paying points, or different in ways that wash out by the time you account for closing costs.
This is why comparing lenders by rate alone is misleading. You have to compare rate + total cost over the same point structure.
What to do with this
Two practical takeaways:
1. When you see a rate quoted, ask what scenario it assumes. “What credit score, what LTV, how many points?” If they can’t answer, the quote is marketing — not a real number for you.
2. When you compare lenders, normalize. Get all of them quoting the same point structure (usually par, meaning no points and no credits) so you’re comparing apples to apples. Then look at total closing costs.
The buyer who does this finds rate spreads of 0.25–0.5% between lenders for the same loan. That’s $50–$100/month forever, on a $400,000 mortgage. It pays to ask the right question.
When I quote you a rate, it’s the actual number for your actual scenario. That’s the whole pitch.
