A Gilded Age, 30-foot-wide Georgian-style brick mansion with a colorful past that was once home to steel magnate Charles M. Schwab is on the market for $22.5 million.

Built in 1898, the home at 323 W. 74th St. is currently configured as an owners’ triplex with four renters, but it can be delivered vacant.

The home is 10,000 square feet, with eight bedrooms, 10 bathrooms, four terraces and four Juliet balconies.

Schwab lived in the home between 1914 and 1917; the place was also a scandalous love nest for Guinevere Jeanne Sinclair — George Gould’s mistress. The broker is Maria Manuche, of Corcoran.
