(Reuters) -The Trump Organization said on Monday it had repaid a $160 million loan on the 40 Wall Street office tower in Manhattan, of which analysts estimate about $114 million was outstanding.

Trump has cited the building, which he said he bought for $1 million, as one of his most successful real estate investments ever. However, in recent years the building struggled with low occupancy and its income has been unable to cover debt payments.

The loan was due for repayment in early July.
