Choosing between an independent mortgage consultant like Duane Buziak and a large online lender like Lower.com comes down to how each one shops your rate and what that costs you over time. Duane Buziak, working through GrandRates’ free comparison service, checks pricing across hundreds of wholesale lenders on a single file, while Lower.com prices your loan against its own rate sheet only. On a $450,000 loan, that structural difference can mean a rate spread wide enough to change your monthly payment by triple digits. This article compares the two models side by side, using a worked loan example, so you can see the practical difference before you apply anywhere, including through GrandRates’ free rate comparison service.
Who Duane Buziak Is and How GrandRates Fits In
Duane Buziak, NMLS #1110647, is an independent mortgage consultant licensed in Virginia, Florida, Tennessee, Georgia, Washington D.C., North Carolina, South Carolina, and Maryland. He operates through Coast2Coast Mortgage, LLC, NMLS #376205. In South Carolina, Duane works strictly as a broker, with no correspondent or in-house funding language applying to that state. In his other licensed states, he functions with both broker and correspondent lending capability, meaning a loan can be shopped across wholesale lenders and, where appropriate, funded in-house.
Duane Buziak, NMLS #1110647, built GrandRates.com as a national rate-comparison platform rather than a single retail storefront. Instead of quoting one company’s rate sheet, GrandRates checks pricing across hundreds of wholesale lenders for a given loan scenario. Each wholesale lender prices loans differently based on its own margins, investor relationships, and volume incentives that week, so the same borrower profile can generate a meaningfully different rate and closing-cost structure depending on which lender’s sheet is used.
This is the core distinction between a broker-model consultant and a single-source lender: a broker is not tied to one rate sheet and can place a loan with whichever wholesale lender prices it most competitively for that borrower’s situation on that day. The comparison itself is free and, in most cases, does not require a hard credit pull to see indicative pricing. That matters for borrowers who want to compare multiple offers without generating several inquiries on their credit file in a short window, a concern the Consumer Financial Protection Bureau addresses directly in its guidance on shopping for a mortgage, which recommends gathering quotes from multiple lenders before committing to one.
GrandRates is not a lender itself. It is the shopping layer that sits in front of the lending decision, letting a borrower see a range of wholesale pricing before deciding whether to lock with a broker-sourced lender, go direct to a retail lender, or compare against an offer already in hand from somewhere like Lower.com or Rocket.
What Lower.com Is and How Its Process Works
Lower.com is a direct-to-consumer online mortgage lender. It originates loans against its own single rate sheet, a structure common among large digital lenders that built their business around a fast, largely automated online application. When you apply with Lower.com, you are pricing your loan against that one company’s cost of funds, margin targets, and investor guidelines, not against a market-wide set of options.
That structure has real trade-offs. A borrower who applies with Lower.com typically receives one lender’s pricing per application. If that borrower wants to compare against a different lender’s rate sheet, the usual path is a second application, and often a second credit pull, at a competing company. Each additional application can mean another inquiry on a credit report, more paperwork, and more time spent re-entering financial details that a broker-model comparison could have surfaced in a single pass.
The digital-first process itself is a legitimate draw for some borrowers. An online-only application, automated document upload, and status tracking through a portal can suit someone who wants a straightforward, self-directed experience without a lot of phone calls. The trade-off is that this convenience is bounded by one company’s pricing. A retail lender’s rate sheet, however competitive on a given day, is still one data point. It does not reflect what hundreds of wholesale lenders might offer the same borrower for the same loan amount, credit profile, and property type.
This is not a claim that Lower.com’s pricing is worse than a broker’s. It is a structural fact: single-lender pricing and multi-lender pricing are different starting points, and the borrower’s job is to know which one they’re getting before they lock a rate. The Consumer Financial Protection Bureau’s rate-lock guidance makes the same point about timing and comparison shopping, noting that rates can vary meaningfully between lenders quoting the same day.
Worked Example: Comparing Pricing on a $450,000 Loan
Consider a borrower financing a $450,000 home purchase with a 30-year fixed conforming loan. As of September 2026, 30-year fixed conforming rates have been trading in a range that Freddie Mac tracks weekly in its Primary Mortgage Market Survey. Rather than assume a single “market rate,” assume this borrower receives two real quotes on the same day: one from a single retail lender’s rate sheet, and one surfaced through a multi-lender wholesale comparison that came in a quarter-point lower due to that day’s investor pricing.
On a $450,000 loan, a 0.25 percentage point difference (for example, 6.75% versus 6.50%) changes the principal-and-interest payment by roughly $75 a month, using standard 30-year amortization math. That may look modest on a monthly statement, but it compounds. Over five years, the borrower with the lower rate pays approximately $4,500 less in interest, money that stays in their pocket rather than going to debt service. Over the full 30-year term, the gap widens into the tens of thousands of dollars, assuming no refinance in between.
The monthly difference matters for qualification too. Loan officers calculate debt-to-income ratios off exact payment figures, so a lower rate can be the difference between qualifying for the exact home a borrower wants and needing to adjust the loan amount or search criteria.
Rate is only half the comparison. Because Duane Buziak’s wholesale access spans hundreds of lenders rather than one company’s product menu, some of those lenders offer no-out-of-pocket closing options structured into the rate, where lender credits offset closing costs in exchange for a modestly higher rate. A single retail lender may or may not have an equivalent option on its own sheet for a given loan scenario. Whether that trade makes sense depends on how long the borrower plans to keep the loan, but having the option to compare it is only possible when more than one rate sheet is in play. This is the practical value of a multi-lender comparison: it does not just find a lower number, it surfaces structurally different loan options that a single-lender quote cannot generate on its own.
Side-by-Side: Duane Buziak/GrandRates vs. Lower.com
The differences between these two models are structural, not a matter of which company tries harder. The table below compares verifiable facts about how each operates.
- Business model: Duane Buziak/GrandRates operates as a mortgage broker and correspondent lender with in-house funding capability in most licensed states (broker-only in South Carolina). Lower.com operates as a direct retail lender originating against its own balance sheet.
- Rate sheets accessed per comparison: GrandRates checks pricing across hundreds of wholesale lenders in a single comparison. A Lower.com application prices against one company’s rate sheet.
- Credit pull for initial comparison: GrandRates’ initial rate comparison typically does not require a hard credit inquiry. A formal application with a direct retail lender generally does, once you move past a soft-pull prequalification stage.
- State licensing footprint: Duane Buziak is licensed in VA, FL, TN, GA, DC, NC, SC, and MD. Lower.com’s licensing footprint is broader and national in scope; borrowers should confirm current state licensing directly with that company, since lender operations and licensing can change.
- Closing-cost structure options: GrandRates’ wholesale access can surface no-out-of-pocket closing options across multiple lenders. A single retail lender’s closing-cost options are limited to whatever that one company offers on its current product menu.
None of this is a subjective claim about service quality, responsiveness, or customer satisfaction. It is a comparison of how each business is structured to price a loan. The core driver of pricing variation between the two models is access: a broker checking multiple wholesale sheets is mathematically more likely to surface a competitive outlier than a single lender checking only its own.
Which Borrower Situation Fits Each Model
Neither model is universally right. The better fit depends on what the borrower values most in the transaction.
A first-time buyer who wants a single, straightforward digital application, minimal back-and-forth, and a self-service portal to track document uploads may be well served by a direct lender’s process. If that borrower isn’t especially rate-sensitive, or their loan amount and profile are simple enough that pricing spread between lenders is likely to be narrow, the convenience of a one-stop online application can outweigh the benefit of shopping multiple sheets.
A rate-sensitive borrower, a real estate investor financing multiple properties, or someone refinancing an existing mortgage has more to gain from a consultant-driven, multi-lender comparison. These borrowers tend to have larger loan amounts, more complex income documentation (self-employed income, rental income, multiple properties), or simply a lower tolerance for leaving money on the table over a 30-year term. For them, checking pricing across hundreds of wholesale lenders before locking is the more defensible move, since even a small rate spread compounds meaningfully on larger balances.
Borrowers located in any of Duane Buziak’s eight licensed states, Virginia, Florida, Tennessee, Georgia, D.C., North Carolina, South Carolina, and Maryland, can use GrandRates to compare pricing before applying with any single lender, including Lower.com, Rocket, or others. This isn’t an either/or decision made in a vacuum. A borrower can request a free comparison, see where wholesale pricing lands that day, and then decide whether a direct application elsewhere still makes sense once they know what the broker channel can offer. For context on loan sizing, the conforming loan limit for most of the country in 2026 is set by the Federal Housing Finance Agency, and high-cost counties within Duane’s licensed states, including parts of Northern Virginia and Maryland, carry higher limits than the baseline figure.
