A Queens landlord was killed by her teen tenant killed during a fight that erupted this week when he failed to make good on rent, authorities said Thursday. 

Davi Vidal, 19, lashed out at Leo Zoraida, 55, around 5:15 p.m. Tuesday inside their building on 96th Street near Northern Boulevard in East Elmhurst, cops said. 

Vidal hadn’t been paying rent, sparking the deadly altercation with Zoraida.

Cops say the landlord was found unconscious and unresponsive with scratches on her face inside an apartment.

She was pronounced dead by responding EMS worker in what has since been deemed a homicide, police said.

Vidal was arrested Wednesday and charged with murder, cops said. 

The NYPD couldn’t say Thursday exactly how Vidal allegedly carried out the assault. 

His arraignment in Queens Criminal Court was pending Thursday.
