| **Item 1.01.** | **Entry into a Material Definitive Agreement.**  |

---

On October 28, 2025, BLKM IV, LLC (the "Borrower"), an indirect subsidiary of BlackRock Monticello Debt Real Estate Investment Trust, a Maryland statutory trust (the "Company"), as borrower, entered into a revolving credit agreement (as it may be amended from time to time, the "Credit Agreement") with CIBC Bank USA ("CIBC"), as lender and administrative agent, and certain other lenders party thereto. The Credit Agreement provides for revolving loans of up to an initial maximum amount of $100.0 million, which may be increased up to a maximum of $250.0 million at the Borrower's request subject to the consent of CIBC and the other lenders, in their sole discretion. The maturity date of the Credit Agreement is October 28, 2028, and is subject to two, one year extensions, at the Borrower's request and subject to the payment of an extension fee and other customary conditions. Advances under the Credit Agreement generally bear interest at a rate per annum equal to the Term Secured Overnight Financing Rate plus 2.0%. In connection with the Credit Agreement, the Borrower will pay an upfront commitment fee of $600,000 and, in the event that the maximum amount of the Credit Agreement is increased, the Borrower will pay an additional commitment fee equal to 0.60% of any such increase. To the extent that total borrowings under the Credit Agreement are less than 60% of the maximum amount available under such Credit Agreement, the Borrower will also pay an unused line fee on a quarterly basis to CIBC as administrative agent on the daily unused amount of the Credit Agreement below such 60% threshold at a rate per annum of 0.25%.

In connection with the Credit Agreement, the Company provided a Guaranty (the "Guaranty"), which may become full recourse to the Company upon the occurrence of certain events as described in the Guaranty.

The Credit Agreement and the Guaranty contain representations, warranties, covenants, events of default and indemnities that are customary for an agreement of its type.
