Room For Rent (2018)

Mitch Baldwin (Mark Little), 32, once won a lottery but squandered all his winnings. He convinces his parents (Mark McKinney, Stephnie Weir) to rent their spare bedroom to save from downsizing.

However, a man named Carl Lemay (Brett Gelman), who has a hidden agenda, becomes their new boarder and soon turns out to be creepier than they could have imagined.
