For most people, a mortgage is both the largest debt and the financing attached to their largest asset, their home. Yet the standard tool most lenders use to help you decide how to structure it is a single rate quote — one rate, one payment, one number, with no comparison to anything else.
If a rate quote is the only information you’re given before making one of the biggest financial decisions of your life, you’re not getting enough to actually decide well. That’s not a knock on rate quotes — they answer a narrow question. It’s just that the question they answer (“what’s my rate and payment on this one scenario?”) usually isn’t the question that matters most to you.
That’s why I provide a Total Cost Analysis (TCA) — not just for every purchase and refinance client, but as part of an annual mortgage review for past clients as well. It’s a digital, side-by-side comparison of several mortgage strategies — not just one — so you can see exactly how each option affects your purchase price, loan amount, rate, payment, closing costs, and long-term costs before you commit to anything.
Why a Rate Quote Alone Isn’t Enough
A rate quote tells you what one lender, on one day, would charge you for one specific structure. What it doesn’t tell you is how that structure stacks up against the alternatives — and there are almost always alternatives. Should you buy down the rate with points, or take a lender credit toward closing costs? Is a price reduction actually worth more than a seller-paid rate buydown? Does a temporary buydown make sense for your timeline, or would a permanent one serve you better?

Those are real decisions with real dollar consequences — and a single rate quote doesn’t surface any of them. You’d have to already know the right questions to ask, then request separate quotes for each variation, then compare them yourself without a consistent format. Most people don’t have the time, the tools, or the mortgage background to do that well. That’s the gap a Total Cost Analysis is built to close.
What’s Included in Your TCA
- Multiple scenarios, side-by-side: Different programs, pricing structures, or negotiating strategies compared in one view.
- Full closing cost detail: Not just an estimated payment — the actual cash needed to close under each option.
- Payment and rate comparisons: How your monthly payment and APR shift across scenarios.
- Time-based comparisons: How each option performs not just at closing, but over months and years — because the cheapest option today isn’t always the cheapest option over time.
- A short video walkthrough: I personally record a video reviewing your specific scenarios, so you’re not left interpreting a spreadsheet on your own.
An Example: Price Reduction vs. Rate Buydown vs. Increased Buying Power
Here’s a simplified example of the kind of comparison a TCA can surface, based on a $700,000 list price with 20% down. A $20,000 seller concession could be applied a few different ways — and each one produces a very different outcome:
| Scenario | Purchase Price | Loan Amount | Interest Rate | Est. Monthly Payment** | Monthly Savings |
|---|---|---|---|---|---|
| List Price (baseline) | $700,000 | $560,000 | 6.500% *APR 6.655% |
$3,539.58 | — |
| Offer $20K Less | $680,000 | $544,000 | 6.500% *APR 6.657% |
$3,438.45 | $101.14 |
| $20K Seller-Paid Buydown | $700,000 | $560,000 | 5.750% *APR 6.259% |
$3,268.01 | $271.57 |
| Increased Buying Power | $665,000 | $523,000 | 6.500% *APR 6.659% |
$3,305.72 | $233.86 + tax/ins. |
*APR estimates assume standard loan costs and will vary by loan scenario. This assumes a 30-year conventional fixed rate. **Monthly payment estimate includes principal and interest only; taxes and insurance are additional. The rate buydown scenario reflects a permanent rate buydown purchased with $20,000 in seller concessions. Individual results will vary. This scenario is for example purposes only — for current rates based on your financial scenario, please request a no-hassle rate quote.
Notice that the $20K seller-paid buydown produces the lowest payment of all four scenarios — more savings than simply asking for $20,000 off the price. But the “Increased Buying Power” column tells a different story too: that same $20,000 concession could instead help you qualify for — and comfortably afford — a home priced closer to $665,000, at a lower loan amount and payment than the baseline. Which path makes sense depends entirely on your goals: lowest possible payment, most house for your budget, or maximum negotiating leverage. This isn’t a coincidence specific to one deal — it’s a pattern I see consistently, and one I’ve written about in more detail:

That’s exactly the kind of insight a rate quote alone won’t show you — and exactly why I build a TCA for every client instead of handing over a single number.
It Also Answers the “Should I Pay Points?” Question
Paying discount points to buy down your rate can make sense — or it can cost you money you’ll never recover, depending entirely on how long you keep the loan. A rate quote won’t tell you if paying points makes sense based on how long you’re planning on retaining the mortgage. A TCA lays it out across scenarios so you can see, in real numbers, whether the upfront cost pencils out for your specific timeline.

Purchases, Refinances, and Annual Reviews
A TCA isn’t just for the day you close. On the refinance side, it’s just as useful for comparing a rate-and-term refinance against a cash-out option, or weighing whether paying points to lower your rate actually pays off within the time you plan to keep the loan.

It’s also a tool I use well after closing. Once you’re a client, I check in with an annual mortgage review — and when it makes sense, that review includes a fresh Total Cost Analysis. Rates change, your equity grows, your goals shift, and mortgage insurance requirements can change too. An annual TCA lays out, side-by-side, whether refinancing, restructuring, or simply staying put is still your best move — so you’re never guessing whether last year’s decision still holds up today.
Why This Matters for Your Decision
This is your largest debt, financing your largest asset. That combination deserves more than a single rate and a single payment on a screen. A Total Cost Analysis gives you the full picture — upfront costs, monthly payment, and how each choice plays out over time — so you can walk into your decision with clarity instead of guesswork.
If you’re considering a purchase or refinance anywhere in King, Pierce, or Snohomish County — or it’s simply been a year since we last talked — I’d be glad to build a Total Cost Analysis specific to your situation, free of charge and with no obligation.

Frequently Asked Questions
Is a rate quote enough to make a mortgage decision?
Usually not. A rate quote shows one lender’s pricing on one specific scenario. It doesn’t compare that scenario against the alternatives — different programs, pricing structures, or negotiating strategies — that could meaningfully change your outcome.
Is a Total Cost Analysis the same as a pre-approval?
Not exactly — a pre-approval confirms what you qualify for. A TCA goes further, comparing strategies within that approval so you can choose the one that best fits your goals.
Is a TCA only for new purchases and refinances?
No. I also use it as part of an annual mortgage review for past clients — checking whether current rates, your equity, or your goals suggest it’s worth revisiting your mortgage strategy.
Does a TCA cost anything?
No — it’s part of the service I provide to every client I work with, whether you’re purchasing, refinancing, or checking in a year later.
Can a TCA compare different loan programs, like FHA vs. conventional?
Yes. It can compare programs, pricing structures, and negotiating strategies side-by-side so you can see the real trade-offs rather than guessing.
