Whether the incurrence of an indebtedness is reasonably foreseeable depends upon the facts and circumstances of each situation. The fact that an organization did not actually foresee the need for the incurrence of an indebtedness prior to the acquisition or improvement does not necessarily mean that the subsequent incurrence of indebtedness was not reasonably foreseeable.
the outstanding principal indebtedness with respect to the acquired property is acquisition indebtedness, even though the original property was not debt-financed property. For example, to house its administrative offices, an exempt organization purchases a building with $600,000 of its own funds and $400,000 of borrowed funds secured by a pledge of its securities. It later sells the building for $1,000,000 without redeeming the pledge. It uses these proceeds to purchase an apartment building which it rents to the public for purposes not described in section 514(b)(1) (A), (B), (C), or (D). The indebtedness of $400,000 is acquisition indebtedness with respect to the apartment building even though the office building was not debt-financed property.
For purposes of the preceding sentence, the date of the gift is the date the organization receives the property.
Whether an organization has assumed and agreed to pay all or any part of an indebtedness in order to acquire the property shall be determined by the facts and circumstances of each situation.
