June 12 (Reuters) - Investment firms Apollo Global Management, Sixth Street and Warburg Pincus are among the initial bidders for Goldman's GreenSky unit, Semafor reported on Monday citing people familiar with the matter.

The bids, submitted on Friday, value GreenSky at "mid-nine figures", the report added, much less than the $2.24 billion Goldman paid when it closed the deal last year.

GreenSky facilitates home improvement loans to consumers. In April, Goldman CEO David Solomon said GreenSky was a "good business" but the bank may not be the best long-term holder given its current priorities.

Apollo, Sixth Street, Warburg and Goldman did not immediately respond to Reuters' requests for comment.
