The average homebuyer gets one mortgage rate quote and accepts it. The careful homebuyer gets five quotes within a week and saves anywhere from $5,000 to $50,000 in lifetime interest. The work involved is roughly four hours total. The arithmetic on this is among the highest hourly returns you will ever generate, and yet most buyers do not do it. This article is the playbook.
Why the 14-day window matters
FICO scoring treats multiple mortgage inquiries within a 14-day window as a single inquiry. This rule exists specifically so that consumers can shop rates aggressively without paying a credit-score penalty for each lender they contact. Some scoring models extend the window to 30 or 45 days. The conservative move is to compress all your shopping into a single calendar week.
This applies only to mortgage inquiries (also auto loans and student loans, with separate windows). It does not apply to credit-card or personal-loan inquiries.
The five lenders to shop
For most buyers, the right shopping list is five lenders that represent different parts of the market:
1. A national online lender (Better.com or Rocket Mortgage). These set the benchmark. Their rates are usually competitive, their process is digital-first, and their pricing is transparent.
2. A local credit union. Credit unions often have the best rates for members, especially on jumbo loans and specialty products. Some are open to anyone in a defined geographic area.
3. A local mortgage broker. Brokers shop wholesale rates from dozens of lenders and pass on the best. They typically charge 1–2% as commission but find rates that more than offset the cost.
4. Your existing bank. Some banks (Chase, Wells Fargo, Citi) offer relationship discounts to existing deposit or investment clients. The discount can be 0.125% to 0.50% on the rate.
5. A specialty lender for your situation. If you are a first-time buyer, ask about state-specific programs. If you are a veteran, get a Veterans United quote. If you are a doctor or dentist, ask about physician loans (BHG Money, SunTrust). The specialty lender's rate may not always win, but they sometimes have niche programs that materially change the math.
The 5-day shopping calendar
Monday: Get rate quotes from Better.com and Rocket Mortgage. Both are quick online forms that produce real quotes within hours.
Tuesday: Call your existing bank and a local credit union. Schedule appointments or online applications.
Wednesday: Submit applications to the bank and credit union you spoke with Tuesday. Schedule a call with a local mortgage broker.
Thursday: Talk to the mortgage broker. Have them shop your application across their wholesale lender network. Apply with the specialty lender for your situation if applicable.
Friday: Compare all five quotes. Pick the best, lock the rate.
Comparing apples to apples
Mortgage quotes are easy to manipulate by lenders who know consumers focus on the headline rate. The right comparison is the APR (which includes most fees), not the interest rate alone. Specifically:
Compare the APR, not the rate. APR includes points, origination fees, mortgage insurance, and most other costs. A 6.50% rate with $4,000 in fees is more expensive than a 6.625% rate with $0 in fees on most loan amounts.
Verify the lock terms. A 30-day lock is typical. Some lenders offer 45- or 60-day locks for slightly higher rates. If your closing might be more than 30 days out, you need a longer lock.
Standardize the points. Points are prepaid interest — paying $4,000 in points to lower the rate by 0.25% means $4,000 in upfront cost. Some lenders quote rates assuming 0 points; others assume 1 point. Get all quotes for "0 points" pricing for a clean comparison.
Read the closing cost estimate. Each lender provides a Loan Estimate (LE) within 3 days of application. Compare the LEs side by side. The lender fees (Section A on the LE) are the parts the lender controls; third-party fees (title, appraisal, recording) are largely fixed.
The negotiating move
Once you have multiple quotes, take the lowest one to the next-lowest lender and ask if they can match. Most lenders will, or get close. The conversation is straightforward: "I have a quote from [lender] at 6.42% with $X in fees. Can you match or beat that?"
This works because mortgage origination is a competitive market with thin margins. Lenders have authority to adjust pricing within bands to win business. You will not get a 1% reduction this way, but 0.10–0.25% is common — and on a $500,000 mortgage, 0.20% is $20,000+ in lifetime interest.
What to do once you have your rate
Lock it. Mortgage rates can move 25 basis points in a single day; not locking when you have a great rate is gambling. The rate lock typically costs nothing if you close within the lock window, and lenders have float-down options if rates drop materially before closing.
From rate lock to closing is typically 30–45 days. Once locked, do not change anything material about your application — no new credit, no job changes, no large deposits, no big purchases. Lenders re-verify before closing, and changes can require re-underwriting.

Frequently asked questions
How many mortgage lenders should I compare?
Three to five is the sweet spot. Most buyers get one quote; the exceptional buyer gets five. The variance among lenders for the same borrower is routinely 25–75 basis points, which translates to $20,000–$60,000 over the life of a typical mortgage.
Will shopping multiple mortgages hurt my credit?
No, if you do it within a 14-day window. FICO scoring treats multiple mortgage inquiries within this window as a single inquiry. Some scoring models extend this to 30 or 45 days.
What's more important: interest rate or closing costs?
It depends on how long you'll keep the loan. For loans you'll pay off or refinance within 5 years, low closing costs matter more. For loans you'll keep 10+ years, the lower rate compounds and matters more. The APR figure attempts to combine both.
Should I lock my rate immediately?
Once you have an accepted offer on a home and your best rate quote, yes. Mortgage rates can move 25 basis points in a single day. Most lock periods are 30 or 45 days at no cost; longer locks (60–90 days) cost slightly more but provide certainty in volatile rate environments.
