Builder's Preferred Lender:
Use Their Lender or Bring Your Own?

A builder incentive can be valuable. Before you sign, compare the written loan terms, the builder contract, and an outside lender’s quote.

Should you use the builder’s preferred lender?

Sometimes. The incentive is real money, but it usually only applies if you finance with the builder’s lender, and the rate, points or fees on that loan can be higher than you would get elsewhere. The builder can tie incentives to its lender. The choice of lender is still yours.

The test is simple. Get a written Loan Estimate from the builder’s lender and one from an outside lender for the same loan (amount, program, term and points), on the same day. Compare total cost over the years you actually expect to keep the loan, and check whether the low rate is a permanent buydown or a temporary 2-1 that resets in year three.

Call Ryan before your first model-home visit

Many builders require your agent to be registered on your very first visit to the sales office. Walk in alone and fill out the guest card, and the builder may treat you as unrepresented on that home from then on. The on-site sales rep represents the builder. Ryan represents you.

Ryan does this at no cost to you. The builder typically pays Ryan’s commission, confirmed in writing before you sign.

What the Builder Incentive Actually Changes

Builder financing incentives are not automatically good or bad. The question is whether the written package works for your loan, your cash to close, and the time you expect to own the home.

Ask this first

Is the quoted rate permanent, or is it a temporary buydown? A permanent buydown changes the note rate for the loan term. A temporary buydown reduces scheduled payments for a limited period, then the payment rises to the note rate. Read the written terms and budget for the payment after the temporary period ends.

Three pieces to compare

Permanent buydown

A permanent buydown uses points or a builder contribution to lower the note rate for the life of the loan. Compare the rate, points, APR, lender fees, cash to close, and how long you expect to hold the loan. The Loan Estimate is the place to make that comparison.

Temporary buydown

A temporary buydown starts with lower scheduled payments and steps up to the note rate. Ask for the full payment schedule in writing, including principal, interest, estimated taxes, insurance, HOA and any community assessment. Do not base your qualification decision on the first temporary payment alone.

Closing cost credit

A builder credit can reduce cash needed at closing, but it should be compared against the complete purchase and financing terms. Ask whether it is tied to a lender, title company, loan type, closing date, or other contract condition. Ryan can help you compare the contract and the two written loan offers before you decide.

The Dual Pre-Approval Strategy: The Correct Approach

Here is the step-by-step process that experienced new construction buyers should follow — regardless of which builder they're purchasing from.

Step 1: Get Pre-Approved by an Independent Lender First

Before visiting any builder's sales center, get pre-approved by an independent lender: a mortgage broker who shops multiple wholesale lenders, your credit union, or a bank with strong mortgage rates. This establishes your market rate baseline. Apply for the same loan type (conventional/FHA/VA) and loan amount you expect to need. Get a formal Loan Estimate.

Why first? Because you need this baseline before you can evaluate the builder's offer. If you go to the builder first, your frame of reference is whatever number they show you — you have nothing to compare it to.

Step 2: Get Pre-Approved by the Builder's Lender

Most builders require a pre-approval from their preferred lender to write a purchase agreement. Do this — but do it AFTER you have your independent Loan Estimate in hand. When you apply with the builder's lender, request a Loan Estimate on the same loan terms (same loan type, same loan amount, same assumed purchase price). You now have two standardized documents to compare.

Step 3: Compare Loan Estimates Side by Side

The Loan Estimate (LE) is a federally mandated, standardized 3-page document. Place both LEs side by side and compare:

Step 4: Calculate All-In True Cost

The comparison is not just rate vs. rate. You need to calculate:

Step 5: Use Your Better Deal as Leverage

Armed with two Loan Estimates and a true all-in cost comparison, you can negotiate. If the independent lender wins on total cost, ask the builder's lender if they can match the independent lender's rate or terms. Some will — especially if you're in a phase with strong builder sales incentives. If the builder's package wins, understand exactly what makes it win and take it confidently.

Compare the written offers, not the sales pitch

ItemWhat to compare
Loan structureSame loan type, term, loan amount, occupancy and lock period.
Rate and pointsNote rate, APR, points, lender fees and any lender credit.
PaymentPayment now and after a temporary buydown ends, plus estimated taxes, insurance, HOA and community assessments.
Cash to closeDown payment, closing costs, builder credit and the conditions attached to it.
Contract timingLock expiration, extension cost, float down terms and the builder’s projected closing date.

A builder’s lender may be the better fit for one buyer and an outside lender may be the better fit for another. FHA, VA, conventional, jumbo and self employed borrowers should all compare the same written scenario rather than assume one lender type wins.

Your RESPA Rights: What the Builder Cannot Do

The Real Estate Settlement Procedures Act (RESPA) is a federal consumer protection law administered by the Consumer Financial Protection Bureau (CFPB). RESPA includes specific provisions that protect homebuyers from being coerced into using a builder's affiliated settlement service providers. Here's what builders CAN and CANNOT do under RESPA:

What Builders CAN Do (Legally)

What Builders CANNOT Do (RESPA Violations)

RESPA Section 8(c)(2) specifically allows builders to offer incentives tied to affiliated service providers, AS LONG AS the buyer is not required to use those services and the arrangement is disclosed. The disclosure requirement is key — ask the builder's lender to provide their Section 8 Affiliated Business Arrangement (AfBA) disclosure, which lists all affiliated entities and the nature of their relationships.

AAR Purchase Contract — Arizona SPDS

Arizona's Seller Property Disclosure Statement law requires sellers to disclose known incentive programs. New construction builders operating in Arizona must comply with disclosure requirements including preferred lender incentive arrangements. Review all disclosure documents provided at contract signing.

The 15 Questions to Ask Before Using a Builder's Preferred Lender

Arizona-Specific Financing Considerations

Arizona's 2026 Conforming Loan Limit: $832,750

Maricopa County and Pinal County (which covers much of the Phoenix metro's expanding edge cities) have a 2026 conforming loan limit of $832,750. Loans at or below this limit qualify for conventional Fannie Mae/Freddie Mac programs — typically lower rates than jumbo loans. If your purchase price is in the $900K–$1M range with 10–20% down, your loan amount may fall right at or below the conforming limit — structure your down payment accordingly to avoid jumbo pricing if possible.

Down Payment Assistance: HOME Plus

Arizona Industrial Development Authority (Arizona IDA) offers the HOME Plus program, which provides up to 4% forgivable down payment assistance toward down payment and closing costs. Eligibility: the program's minimum credit score, $155,386 income limit, primary residence, FHA/VA/Conventional/USDA eligible loans. This program can be used WITH a builder purchase — the builder may not market it because they prefer you use their affiliated down payment assistance programs (which may generate more revenue for them). Ask your independent lender about HOME Plus before assuming the builder's program is your only option.

Community Facilities District (CFD) and DTI

Many Arizona new construction communities have Community Facilities District assessments that appear on the property tax bill — not in HOA dues. When your lender calculates your debt-to-income ratio (DTI), they use a property tax estimate that may or may not include the CFD. Ensure your lender is using the full PITI (principal, interest, taxes, insurance) calculation that includes HOA fees AND the CFD equivalent monthly amount. A buyer who looks qualified at 43% DTI can become unqualified if a $1,800/year CFD ($150/month) wasn't included in the underwriting calculation.

Lock strategy for new construction

Ask each lender for its lock period, extension policy, estimated cost, float down option if any, and the condition that can change the lock. A long build timeline does not make one strategy automatically better. Compare the written terms against the builder’s projected completion schedule.

When either option can make sense

The builder lender may make sense when the complete written package produces a lower cost or better cash to close for the same loan. An outside lender may make sense when its written terms are better for your loan type, financial profile, or timing. Neither conclusion should be assumed from the headline incentive.

Frequently Asked Questions — Builder Lender vs. Your Own Lender

Can an Arizona builder require you to use their lender?
A builder may attach an incentive to a financing arrangement, but the purchase contract and written incentive terms control the transaction. Before signing, ask the builder to identify every condition tied to the incentive and have your agent review the contract. A lender determines qualification and loan terms.
What is a 2/1 buydown and how does it work?
A 2/1 buydown is generally a temporary reduction in the borrower’s payment during the early years of the loan. Written loan documents should show the note rate, temporary payment schedule, payment after the buydown ends, who funds it, and what happens to unused funds if the loan is paid off or refinanced. Budget for the full payment, not only the introductory payment.
When should you use the builder's preferred lender in Arizona?
Use the lender whose written package is better for your actual purchase. Compare the same loan program, amount, term, points or credits, rate lock, APR, projected payment, closing costs, cash to close, and every builder incentive condition. Get the builder’s incentive in writing and compare it against an outside lender’s written estimate before deciding.
What is a Loan Estimate and why does it matter?
For most closed end mortgages, a Loan Estimate is the standardized form used to compare loan terms after an application. Compare the same program and assumptions, including the rate lock, points or credits, APR, projected payment, closing costs, cash to close, and prepayment terms. A Loan Estimate is not approval, and the lender determines final qualification and terms.

Evaluating a Builder's Financing Package?

Tell Ryan which builder and community you're looking at — he can help you evaluate the financing package before you commit.

Builder lender and title incentives

A builder may offer incentives tied to a preferred lender, title company, or both. That does not decide whether the package is right for you. Read each condition, ask for affiliated business disclosures where applicable, and compare the written charges and credits with an outside option.

Ryan helps new construction buyers separate the community decision from the financing decision. He can review the builder’s incentive sheet, the contract timing, the Loan Estimate and the disclosure package before you commit.

Home Warranty: The Third Builder Affiliated Service

Builder warranty terms and third party home service contracts are separate products. Read the builder’s written warranty, the service contract, exclusions, deductibles, claim process and the exact terms of any incentive before treating a warranty as part of the financing value.

Are Extended Warranties Worth It in New Construction?

Do not assume an extended plan duplicates or improves the builder warranty. Compare its covered systems, exclusions, service fees and term with the warranty already included in the purchase documents.

Mortgage Broker vs. Direct Lender for New Construction — Which Is Better?

When evaluating "independent lenders" for comparison, you have two main categories: direct lenders (banks, credit unions) who originate and fund from their own balance sheet, and mortgage brokers who originate loans but fund through wholesale lender partners (banks, credit unions, and specialty lenders who lend through the broker channel).

Direct Lender Advantages

Mortgage Broker Advantages

The Right Answer for New Construction Buyers

For most new construction buyers in Arizona, a mortgage broker comparison is the most efficient way to establish your market rate baseline. A good mortgage broker will pull your credit once (soft pull to start, hard pull at application) and shop your scenario to their wholesale network, returning multiple Loan Estimates for comparison. This takes 24–48 hours. You then compare the best broker quote against the builder's lender offer using the standardized Loan Estimate format — and make your decision from a position of complete information.

When to lock a rate for new construction

Ask for the lock terms in writing. Compare the lock expiration, extension policy, any float down option, estimated cost, and what happens if the home is delayed. Ryan can help you match those terms to the builder’s contract schedule, but the lender provides the rate and lock advice.

What Happens at Closing: Dry Closing in Arizona

Arizona closings commonly involve signing, funding and recording on the same day, but timing varies by transaction. Confirm the handoff and recording schedule with your title company and lender before closing.

The Bottom Line: A Simple Framework for Your Decision

After reading this guide, here is the simple framework to apply:

  1. Ask the first question: "Is this rate permanent or a temporary buydown?" If temporary — calculate the step-up payments and make sure you can afford Year 3 at full market rate.
  2. Get your independent Loan Estimate first. Before applying with the builder, establish your market baseline from a mortgage broker or credit union.
  3. Apply with the builder's lender and get their Loan Estimate. Now you have two standardized documents to compare.
  4. Calculate all-in cost — base price, closing costs, and interest paid over your expected hold period — for both options. The option with the lower all-in cost wins.
  5. Factor in service quality. If the numbers are close ($2,000–$5,000 difference over 5 years), the lender with better reviews, clearer communication, and a smoother process may be worth the small cost difference.
  6. Ask all 15 questions. Any evasion or red flag answers are signals worth heeding.
  7. Make the decision from information, not from sales pressure. Builder sales agents are incentivized to push their preferred lender — that's their job. Your job is to evaluate objectively and choose what's best for your financial situation.
