Builder Preferred Lender 2026: What Buyers and MLOs Need to Know About Their Rights

Builder preferred lender arrangements are legal and widespread in the new construction market. A builder may have an affiliated mortgage company or a preferred lender relationship with a specific bank or mortgage company. They can recommend that lender, offer financial incentives tied to using that lender, and market the relationship heavily. What they cannot do is require the buyer to use their preferred lender as a condition of the purchase contract.

RESPA Section 8 Framework

RESPA Section 8 prohibits kickbacks and unearned fees in settlement service referrals. A builder who shares in the lender's profits, receives undisclosed compensation for referrals, or uses an affiliated business arrangement (AfBA) without proper disclosure is in RESPA violation territory. Affiliated arrangements are legal if an AfBA disclosure is provided and the buyer is not required to use the affiliate. The AfBA must be disclosed at the time the referral is made.

What the Preferred Lender May Actually Offer

The builder's preferred lender often has real operational advantages: they know the project's PERS approval status, they have relationships with the builder's title and escrow partners, and they may have dedicated underwriting for the builder's product. These are legitimate reasons to consider them. The question is whether their rate, fees, and total cost are competitive after accounting for the builder incentives tied to their use.

• ✦If the builder's contract has language requiring the preferred lender, flag it for the buyer's attorney
