Is it a red flag if a middle aged man sublets a room in his house because he craves companionship?

Im recently looking for a flatshare and found an advertisement of a 49 year old father of two kids who was subletting a room in his house. I messaged him and we quickly exchanged numbers. After he saw my picture he couldn’t wait to invite me over and seemed very desperate to sell it. I figured that as a single parent he must be desperately in need for the money so I didn’t think Much of it. When i met him the next day he was very happy to see me and seemed a bit nervous. We talked about 3 hours in his kitchen and meanwhile he kept telling me that my presence makes him happy, that I have very nice eyes and a charming smile. During the entire conversation he was never making any overt sexual advances and he wasn’t pushy. He mentioned that he owns this house which made wonder why he needs to sublet any rooms to which he replied that he probably wouldn’t take any money from me and that he is missing companionship after being divorced for 3 years. While saying that he seemed very ashamed and couldn’t look me in the eye. He is a musician, gifted (iq > 130) and so are his kids so he is not just some kind of sleaze bag that doesn’t have his life together. Is he a red flag? I feel a bit sorry for him tbh
