Why the Lowest Rate Is Not Always the Best Deal

The rate trap

Most borrowers obsess over the interest rate. Lenders know this — so some advertise a low rate and bury $8,000 in points and fees to get you there. That low rate could cost you more than a slightly higher rate with zero fees.

Example: the rate vs. cost trade-off

Scenario: $350,000 loan, 30-year fixed. Two offers:

• Offer A: 6.25% rate, $7,500 in points + lender fees.
• Offer B: 6.75% rate, $500 in lender fees.

Offer A saves you $109/month vs. Offer B ($2,155 vs. $2,264). That sounds good until you realize it costs $7,500 extra to get there. The break-even is 69 months (almost 6 years).

If you sell or refinance before year 6, Offer B was the better deal — even though the rate is higher.

APR is helpful but not perfect

APR factors in points, broker fees, and some closing costs. But it has flaws:

• It assumes you keep the loan for the full term (most people sell or refi within 7–10 years).
• It does not include all fees (title insurance, appraisal, recording fees).
• It can be gamed by lenders who exclude certain costs from the calculation.

Use APR as one data point, not the deciding factor.

What to actually compare

When comparing two Loan Estimates, look at Section A (origination charges) and Section B (services you cannot shop for) on each form. Add them up. Then look at the rate. The best deal is the one with the lowest total cost over the time you plan to keep the loan.

The broker advantage

A broker will show you multiple rate/fee combinations and explain the break-even math. A bank typically shows you one option — their "best rate."

• 6.5% with 0 points: $2,200/month, $2,000 in fees.
• 6.25% with 1 point: $2,155/month, $5,500 in fees.
• 6.75% with lender credit: $2,264/month, $0 in fees (lender pays $2,000).

Which is best? It depends on your plan. A broker helps you see that — a rate sheet does not.
