The purposes of this Supplement are as follows:

April 1, 2026 Transaction Price

The transaction price for each share class of our common stock for subscriptions accepted as of April 1, 2026 (and repurchases, if applicable, as of March 31, 2026) is as follows:

As of February 28, 2026, we had not sold any Class S or Class D common shares. The transaction price for each of our Class S and Class D common shares is based on the NAV per share for our Class I common shares as of February 28, 2026. We will separately calculate the NAV per share of each one of our share classes once we have shares of that class outstanding. Class A-I, Class A-II and Class E common shares and Class E units are not sold as part of this offering. A detailed presentation 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, except those shares that have not been outstanding for at least one year will be repurchased at 98% of the transaction price.

February 28, 2026 NAV per Share

We calculate NAV per share 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.eqrt.com. Please refer to the "Net Asset Value Calculation and Valuation Guidelines" in the Prospectus for important information about how our NAV is determined. The Adviser is ultimately responsible for the determination of our monthly NAV. We have included a breakdown of the components of total NAV and NAV per share/unit as of February 28, 2026 along with a comparable breakdown for the immediately preceding month.

Our total NAV presented in the following tables includes the NAV of our outstanding classes of common stock as of February 28, 2026 as well as Class E units of our Operating Partnership held by an affiliate of our Sponsor. The following table provides a breakdown of the major components of our total NAV as of February 28, 2026 ($ and shares/units in thousands):

_______________________________________

(1) Distribution fees only apply to Class T, Class S and Class D common shares. For purposes of calculating our NAV, we recognize the distribution fees as a reduction of our NAV on a monthly basis as such fee is paid. Under accounting principles generally accepted in the United States of America ("GAAP"), we accrue the lifetime cost of the distribution fees as an offering cost at the time we sell Class T, Class S or Class D common shares. As of February 28, 2026, we had accrued $1,473 of distribution fees under GAAP payable to the Dealer Manager related to the sale of Class T shares. The Dealer Manager does not retain any of these fees. The Dealer Manager will reallow (pay) all or a portion of the distribution fees to selected dealers and servicing broker-dealers, and will rebate distribution fees to us to the extent a broker-dealer is not eligible to receive them.

The following table sets forth our total NAV and NAV per share/unit by class as of February 28, 2026 ($ and shares/units in thousands, except per share/unit data):
