The Blood Let (2015)

Ex-cop Gus is all messed up and in therapy after he was shot in the line of duty. He takes a job as a resident manager of a creaky old, creepy apartment building, The Royal Vista Apartments. It would seem that his new employment would be a piece of cake compared to his last job as a police officer, but not so. Tenants start dying, left and right, bizarre and bloody deaths. The greedy old owner, Wang, puts unrelenting pressure on Gus to "Rent apartments!!! Rent Apartments!!!" Gus finally gives in and makes a fateful error in judgment. He rents to vampires.
