On Aprill 22, 2026, Redwood Mortgage Investors IX, LLC, a Delaware limited liability company (the "Company"), dismissed BDO USA, P.C. ("BDO") as the Company's independent registered public accounting firm. On April 22, 2026, the Company engaged Baker Tilly US, LLP ("Baker Tilly") as the Company's new independent registered public accounting firm. The decision to dismiss BDO and appoint Baker Tilly was approved by the Company's manager, Redwood Mortgage Corp.

The auditors' reports of BDO regarding the Company's financial statements for the fiscal years ended December 31, 2025 and 2024 did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2025 and 2024, and during the subsequent interim period from January 1, 2026 through April 22, 2026, there were (a) no disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions) with BDO on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures which disagreements, if not resolved to the satisfaction of BDO, would have caused it to make reference to the subject matter of such disagreement in its reports and (b) no reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K), except that the Company identified a material weakness in its internal control over financial reporting which pertains to internal controls over the Company's evaluation of expected future credit losses, including determination of the current fair value of certain real properties collateralized against respective loans, not being prepared or reviewed in a timely manner. As disclosed in Item 9A, Controls and Procedures, of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "2025 Form 10-K"), the Company remediated this material weakness as of December 31, 2025 through the implementation of remediation steps that improved the Company's disclosure controls and procedures and its internal control over financial reporting. Please refer to the disclosure contained in Item 9A, Controls and Procedures of the 2025 Form 10-K for additional information regarding such remediation.

The Company provided BDO with a copy of the disclosures it is making in this report and requested that BDO furnish a letter to the Company addressed to the Securities and Exchange Commission stating whether BDO agrees with the statements made herein and, if not, stating the respects in which it does not agree. A copy of BDO's letter dated April 24, 2026 is attached as Exhibit 16.1 hereto.

During the fiscal years ended December 31, 2025 and 2024 and during the subsequent interim period from January 1, 2026 through April 22, 2026, neither the Company nor anyone on its behalf consulted with Baker Tilly regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, and no written report or oral advice was provided to the Company that Baker Tilly concluded was an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions), or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K).
