Read this OP from the book 'The Gift of fear.'
en.wikipedia.org/wiki/The_Gift_of_Fear
Forced Teaming. This is when a person implies that they have something in common with their chosen victim, acting as if they have a shared predicament when that isn't really true. Speaking in "we" terms is a mark of this, i.e. "We don't need to talk outside... Let's go in."
Charm and Niceness. This is being polite and friendly to a chosen victim in order to manipulate him or her by disarming their mistrust.
Too many details. If a person is lying they will add excessive details to make themselves sound more credible to their chosen victim.
Typecasting. An insult is used to get a chosen victim who would otherwise ignore one to engage in conversation to counteract the insult. For example: "Oh, I bet you're too stuck-up to talk to a guy like me." The tendency is for the chosen victim to want to prove the insult untrue.
Loan Sharking. Giving unsolicited help to the chosen victim and anticipating they'll feel obliged to extend some reciprocal openness in return.
The Unsolicited Promise. A promise to do (or not do) something when no such promise is asked for; this usually means that such a promise will be broken. For example: an unsolicited, "I promise I'll leave you alone after this," usually means the chosen victim will not be left alone. Similarly, an unsolicited "I promise I won't hurt you" usually means the person intends to hurt their chosen victim.
Discounting the Word "No". Refusing to accept rejection.
All of this sounds like your creepy male neighbour.
Trust your instincts. And know that he would not be behaving like this if you were a man. He knows you are more vulnerable and he is playing on it.
Ignore the people on here trying to play it down and dismiss you and take the piss out of you. I am fucked off with seeing people saying if THEY wouldn't have a problem with it, then YOU have no right to. So fucking arrogant! 
If this kind of thing was happening to them or their sister or daughter - a man being over friendly and freaking them out, it would be a different matter. Ignore the naysayers. It's not happening to them - it's happening to you.
You can tell the posters who do not like people having a different opinion to them. They keep repeating that the thread is 'bonkers' and mocking and scoffing and acting like anyone who disagrees with them is an idiot!
Upshot is, the OP feels uncomfortable in the presence of this man. If any women on here feels GREAT in the company of hairy arsed bikers, big pistons, men walking with them in a dark alley, men gawking at them over the fence and making innuendo, a man they barely know asking personal questions, or a man who looks at your tits instead of your face when he's talking to you, then fucking bully for you. But this is not how the OP feels. So quit dismissing and minimising how she feels. It's making you look foolish, sanctimonious, and arrogant.
