(1)Stockholder servicing fees only apply to Class S, Class T and Class D shares. For purposes of NAV we recognize the stockholder servicing fee as a reduction of NAV on a monthly basis. Under accounting principles generally accepted in the United States of America (“GAAP”), we accrue the full cost of the stockholder servicing fee as an offering cost at the time we sell Class S, Class T and Class D shares. As of March 31, 2024, we have accrued under GAAP $272.9 million of stockholder servicing fees payable to the Dealer Manager related to the Class S, Class T and Class D shares sold.

The following table provides a breakdown of our total NAV and NAV per share, by share class, as of March 31, 2024 ($ and shares/units in thousands, except per share/unit data):

Set forth below are the weighted averages of the key assumptions in the discounted cash flow methodology used in the March 31, 2024 valuations, based on property types. Once we own more than one single-family, one self-storage and one extended stay investment, we will include the key assumptions for the property types.

Property Type	Discount Rate	Exit Capitalization Rate
Multifamily	6.8%	5.5%
Industrial	7.2%	5.6%
Office	7.9%	6.6%
Other	8.2%	6.8%

For quarter-end months, these assumptions are determined by the independent valuation advisor or third party appraisers, as applicable, per the terms of our valuation guidelines. The Advisor reviews the assumptions from each of the appraisals. A change in these assumptions would impact the calculation of the value of our property investments. For example, assuming all other factors remain unchanged, the changes listed below would result in the following effects on our investment values:

2

Input	Hypothetical Change	Multifamily Investment Values	Industrial Investment Values	Office Investment Values	Other Investment Values
Discount Rate	0.25% decrease	+1.9%	+2.0%	+1.9%	+1.9%
(weighted average)	0.25% increase	(1.9)%	(1.9)%	(1.9)%	(1.8)%
Exit Capitalization Rate	0.25% decrease	+2.9%	+3.0%	+2.4%	+2.2%
(weighted average)	0.25% increase	(2.7)%	(2.7)%	(2.2)%	(2.1)%
