What an Aggregator Can Change in a Seller Guide

Nearly everything in the guide, at any time, in the aggregator’s sole discretion — and the guide is where most of the operative deal terms live. In the Washington Mutual form filed with the SEC, the agreement itself “may not be amended except by an instrument in writing signed on behalf of each of the parties,” while the guide “may be amended or supplemented by Purchaser from time to time in Purchaser’s sole and absolute discretion.” Published guides then close the loop by deeming the seller to have consented the next time it registers, locks, commits, or delivers a loan.

How does a seller guide become part of the contract?

The purchase agreement is short by design. The Washington Mutual form runs five pages and spends its first article on this question: the Seller Guide “is incorporated by reference in its entirety into this Agreement,” and its provisions “constitute a material part of this Agreement, as if they were expressly set forth herein.” It then inverts the hierarchy a seller might expect: “In case of any inconsistency between this Agreement and the Seller Guide, the terms and provisions of the Seller Guide shall control.”

Current guides keep the architecture. Spring EQ treats the purchase agreement, a credit approval exhibit, and the guide as components of one “Agreement.” Plaza calls its set the Program Documents, “subject to modification by Plaza at its sole discretion.”

How broad is the amendment right as actually drafted?

Broader than most negotiated commercial terms, and drafted without qualifiers. Spring EQ “reserves the right to amend or supplement the Guide at any time at its sole discretion,” by notice to the seller “and/or by posting such amendments or supplements on the Spring EQ Correspondent Website.” Arc Home’s guide “may be amended by Arc Home without notice from time to time in Arc Home’s sole discretion,” with the resulting notices, bulletins, and changes “immediately binding upon Seller.” Plaza separately reserves the right to amend continuing eligibility standards.

The right can reach past the guide into the executed agreement: Spring EQ’s Credit Approval Exhibit, which sets program eligibility and commitment credit limits, “can be amended by Spring EQ at its sole discretion, effective immediately or at another specified date, by giving notice to Seller.”

None of these provisions conditions the right on materiality, reasonableness, good faith, non-discrimination across the seller base, or consistency with agency requirements.

Is the notice period real?

In the guides read for this piece, none of it is measured in days. Plaza is the most protective: “The notice will explain the update and specify the effective date of the change.” Spring EQ’s announcements “will become effective immediately or on such later date as Spring EQ may determine.” Arc Home’s amended guide “shall govern immediately upon amendment,” and the seller must “independently confirm that Seller is operating under the most current Seller’s Guide.”

Specifying an effective date is not the same as giving lead time before it. Where posting alone suffices, a seller watching only its inbox is watching the wrong channel.

Does a change reach loans already locked, committed, or funded?

The guides differ, and the difference decides whether an amendment is an inconvenience or a loss. Spring EQ draws the line at commitment: “the Sale and Purchase of each Mortgage Loan hereunder will be subject to all requirements of the Guide in effect on the related Commitment Date.” Its underwriting representation is anchored the same way, to the program guides “in effect at the time of Lock Confirmation.”

The Washington Mutual form instead makes pipeline activity the consent mechanism: “If Seller registers, locks or delivers a Mortgage Loan after receiving notice of a proposed amendment, Seller shall be deemed to have agreed to such amendment.” Plaza uses the same structure at commitment. Under Arc Home’s formulation, the amended guide simply governs on amendment.

Funded loans are a separate problem. An amendment does not rewrite a representation already made, but where the representation is compliance with a document that changes, the obligation travels with the document. One filed agreement has the seller representing that it “has strictly complied with all requirements set forth” in the purchaser’s lending manual “as such Manual may he [sic] amended from time to time in Purchaser’s discretion” — made at commitment and again at sale.

What actually changes mid-stream?

Underwriting overlays, eligibility and program cut-offs, early payoff and early payment default terms, repurchase triggers, and indemnity scope — the terms that price the relationship. Those economics are agreement-specific; read them in the operative document rather than assume them. One filed agreement requires refund of “the servicing release premium and any rebate pricing paid by Purchaser at the time of purchase” where a loan prepays in full within 120 days of sale, and requires repurchase on written request if any one of the first four monthly payments becomes 90 days or more delinquent. Those are that agreement’s numbers, not a market standard.

What can a seller realistically negotiate?

Three asks. The first is already drafted into a public guide; the other two are ordinary commercial terms.

First, an effective-date carve-out for the pipeline — amendments apply only to loans locked or committed on or after the effective date. Spring EQ’s commitment-date language is a usable model.

Second, a notice floor: a stated number of days between notice and effective date for underwriting eligibility, pricing adjustments, repurchase triggers, and indemnity scope, by direct written notice rather than posting alone.

Third, a right to terminate without penalty on a material adverse amendment, with outstanding commitments honored on pre-amendment terms. The default may be worse than it looks: in one filed agreement the term runs until termination “by the mutual written consent of the Seller and Purchaser,” with no unilateral seller exit.

Practitioner takeaway

Read the amendment clause before the credit box. Today’s guide is the one term the counterparty can change tomorrow. Ask three questions: what does the amendment right reach, when does a change bind, and what happens to the pipeline. If the answers are “everything,” “immediately,” and “it moves,” the guide is a one-way document — a negotiable point, not a market condition.
