Investment Portfolio Updates

In March 2026, we acquired 34 Market Street, a 222,000-square-foot Class A warehouse and distribution facility in Everett, Massachusetts, less than five miles from downtown Boston, for approximately $155 million. The asset is fully triple-net leased to an investment-grade tenant, with 12 years of remaining lease term.

As of March 31, 2026, our portfolio, based on the NAV of our investments, consisted of 90% real estate properties and 10% real estate-related loans and securities. NAV is measured as the fair value of our investments less any mortgages or debt obligations related to such investments.

As of March 31, 2026, our real estate properties, based on the total asset value of our properties measured at fair value, consisted of multifamily (44%), net lease (20%), logistics (20%), single-family rental (9%), student housing (5%), and office (2%).

May 1, 2026 Transaction Price

The transaction price for each share class of our common stock for subscriptions accepted as of May 1, 2026 (and repurchases as of April 30, 2026) is as follows:

						Transaction Price (per share)
Class S						$	10.2547
Class I						$	10.3689
Class D						$	10.4652
Class T						$	10.4560

The May 1, 2026 transaction price for each of our share classes is equal to such class's NAV per share as of March 31, 2026. A detailed calculation of the NAV per share is set forth below. The purchase price of our common stock for each share class equals the transaction price of such class, plus applicable upfront selling commissions and dealer manager fees. The repurchase price for each share class equals the transaction price of such class.

March 31, 2026 NAV Per Share

NAV per share is calculated in accordance with the valuation guidelines that have been approved by our board of directors. Our NAV per share, which is updated as of the last calendar day of each month, is posted on our website at www.BrookfieldREIT.com and is made available on our toll-free, automated telephone line at (833) 625-7348. Please refer to "Net Asset Value Calculation and Valuation Guidelines" in the Prospectus for important information about how our NAV is determined. We have included a breakdown of the components of total NAV and NAV per share for March 31, 2026 along with the immediately preceding month.

Set forth below are the weighted averages of the key assumptions in the discounted cash flow methodology used in the March 31, 2026 valuations, based on property types. In the event that we own more than one office investment in the portfolio, we will include the key assumptions for that property type.

Property Type						Discount Rate						Exit Capitalization Rate
Multifamily/Student Housing						7.3%						5.8%
Single-Family Rental						7.2%						5.4%
Net Lease						6.9%						5.4%
Logistics						9.3%						6.3%

A change in these assumptions would impact the calculation of the value of our property investments. For example, assuming all other factors remained unchanged, the changes listed below would result in the following effects on our investment values:

Input						Hypothetical Change						Multifamily/Student Housing Investment Values						Single-Family Rental Investment Values						Net Lease Investment Values						Logistics Investment Values
Discount Rate						0.25% Decrease						1.9%						1.1%						2.1%						1.9%
(weighted average)						0.25% Increase						(1.8)%						(1.1)%						(2.0)%						(1.8)%
Exit Capitalization Rate						0.25% Decrease						2.7%						3.7%						2.8%						2.6%
(weighted average)						0.25% Increase						(2.4)%						(3.3)%						(2.5)%						(2.5)%

The preceding tables do not include recently acquired properties, which are held at cost in accordance with our valuation guidelines.
