A Manhattan landlord was busted Thursday for lying on paperwork to score a multimillion-dollar loan for a rental property on the Lower East Side, authorities said.

Dean Galasso was nailed during an investigation into tenant complaints of harassment and unsafe conditions at the building, officials said.

Tenants told the blog Bowery Boogie that Galasso shut off their cooking gas for a year and turned off the heat and hot water in January 2016 just before a snowstorm hit the city.

Galasso, 49, submitted phony documents to Investors Bank to obtain a $5,025,000 mortgage to finance the purchase of a 10-unit building, according to a statement from state Attorney General Eric Schneiderman’s office.

Galasso submitted forged leases and false rent-roll information for 43 Essex St., which the bank relied on to approve the loan, officials said.

“Bad landlords are now on notice: if you attempt to break the law, we will find you and prosecute you to the fullest extent of the law,” AG Schneiderman said in a statement.

Galasso, who owns numerous properties in Manhattan and Queens, faces charges of grand larceny, forgery and other raps.

He bought the property for $6.9 million in 2014, real-estate records show.
