debt-financed property.
To the extent that the use of any property is substantially related (aside from the need of the organization for income or funds or the use it makes of the profits derived) to the exercise or performance by an organization of its charitable, educational, or other purpose or function constituting its basis for exemption under section 501 (or, in the case of an organization described in section 511(a)(2)(B), to the exercise or performance of any purpose or function designated in section 501(c)(3)) such property shall not be treated as debt-financed property. See 1.5131 for principles applicable in determining whether there is a substantial relationship to the exempt purpose of the organization.
