Something we tell every single client, and we’re going to keep saying it until everyone hears it: please, shop your rate.

We had a client last week who almost went with the first lender she spoke to. We’re so glad she didn’t. Here’s what most people don’t realise about comparing mortgage rates: two people with the exact same credit score and income can walk away with rates that are nearly half a point apart, just based on which lender they choose.

Why the Same Borrower Can Get Two Different Rates

It sounds like it shouldn’t be possible to have the same credit score, same income, same down payment and yet mortgage interest rates vary meaningfully from lender to lender. Every lender prices risk a little differently, has different overhead, different investor relationships, and a different appetite for the type of loan you’re applying for on any given day. Rates are also moving constantly right now, which means the “good rate” you hear about from a friend or see in an ad may already be out of date by the time you apply.

The result is that shopping around for a mortgage isn’t just a nice-to-have, it’s often the single biggest lever you have over what you’ll actually pay.

What Half a Point Actually Costs You

A half-point difference in your mortgage rate might sound small on paper. It isn’t. On a typical loan, that gap can translate to £100 or more per month and that’s not a one-time cost. That’s every month, for the life of a 30-year loan.

Run the math over three decades, and a difference that looked negligible on day one can add up to tens of thousands of pounds by the time the loan is paid off. That’s the cost of picking a lender based on convenience rather than comparison.

We’re Not Saying Don’t Trust Your Lender

To be clear: this isn’t about distrusting your bank or your loan officer. Most lenders are perfectly reputable, and there’s nothing wrong with the one you’re already talking to. The point is simpler than that get at least 2–3 mortgage quotes before you commit to anything. It takes a few hours of your time. It could save you tens of thousands of dollars over the life of your loan.

How to Actually Compare Mortgage Quotes

Shopping your rate is only useful if you’re comparing quotes properly. A few things to keep in mind:

Compare the APR, not just the interest rate. The APR includes lender fees and closing costs, giving you a more accurate picture of the total cost of the loan.

Get quotes within a short window. Rate shopping for a mortgage within a focused period (typically around 14–45 days, depending on the credit scoring model) is generally treated as a single inquiry rather than multiple hits to your credit.

Compare like-for-like loan terms. Make sure each quote reflects the same loan type, term length, and rate lock period, so you’re not comparing a 30-year fixed rate to a 5-year adjustable one.

Ask about lender fees separately. A slightly higher rate with lower fees can sometimes beat a lower rate loaded with costs the APR comparison helps surface this, but it’s worth asking directly too.

You Wouldn’t Buy the First Car on the Lot

You wouldn’t walk onto a car lot and buy the first car you see without comparing prices elsewhere. Your mortgage a loan you’ll likely be paying for decades deserves at least that same energy.

Frequently Asked Questions

Does shopping around for a mortgage hurt my credit score? Multiple mortgage inquiries made within a short, focused window are typically counted as a single inquiry by credit scoring models, so comparing a few lenders in the same timeframe has minimal impact.

How many mortgage quotes should I get? Most guidance suggests at least 2–3 quotes, which gives you enough to compare meaningfully without dragging the process out.

What’s the difference between interest rate and APR? The interest rate is the cost of borrowing the loan amount itself. The APR adds in lender fees and other closing costs, giving a fuller picture of the loan’s true annual cost which is why it’s the better number to compare across lenders.

Why would two borrowers with the same credit score get different rates? Every lender prices risk differently based on their own criteria, overhead, and market conditions on any given day, which is exactly why comparing quotes rather than assuming one lender’s offer is the market rate matters so much.
