What Would You Do?

So, the guy across the street from our new lots we are about to build on has shown everyone that he is going to be a "problem person". Long story short: He ripped out all of the perfectly nice grass he had in the front yard and then started to seed new grass. The neighborhood covenants require that all front yards be sodded. Never an issue until now. 4 neighbors went to this guy and nicely told him that he was not allowed to seed the yard and he needed to do sod. He told them he was aware of that, but he was going to do what he wanted and did not care about the covenants. (Which he signed and agreed to when he bought the house....) So, these same neighbors called the developer- who is still the president of the HOA and told him he needed to deal with it. Developer sent the guy a letter. Guy asks the landscaper to find out who called and reported him. Landscaper finds out and tells guy. Guy goes around to every house of neighbors who reported him (at 9 O CLOCK AT NIGHT) and rants and raves about how wrong it was for them to call and report him. He also finds out that B and I asked the developer about it because we wanted to make sure we were not moving into a neighborhood where the covenants were not going to be upheld. He has told everyone that he still fully intends to seed his yard. Now we are waiting to see if the developer will handle it. He also told my aunt (who lives there) that he is very angry we bought the lots across from him and he had fully intended to buy them and that our house better not block his view of the farmland behind us. Now, all of the other people in the neighborhood are in agreement that this guy should be dealt with. It remains to be seen if he actually gets dealt with. I don't know why he thinks he is exempt from the covenants or why he thinks he should just be able to do whatever. He told my aunt that he" had all these same kinds of problems in his last neighborhood". She said, "Well, that should tell you something, buddy." He just cannot stand her because she is one of the ones who reported him. His wife, who is very sweet and quiet, just sat there and cried while he went around ranting about all of this. We're not second-guessing the lots because, like I said, all of the other people in the neighborhood are really nice and he is the only one like that. The girls are going to love it there and we love it there. But, I am almost afraid that this guy is going to make our lives a living hell when we move there and part of me is even afraid he will do things to our house while it is under construction. It wouldn't be so bad if he weren't directly across the street from us. And it's not like he'll be moving anytime soon- they just moved there a few weeks ago. He also told my aunt that when he yelled at us to get off that lot the evening we took my parents to see it, that he meant it. We have not even closed on the lots and he already hates us. We are waiting to see what the developer does to handle this guy. I'm afraid if he does not handle it swiftly and firmly that this guy will just keep trying to see what he can get away with out of spite. I knew when I saw him come out of his house in an undershirt and socks pulled up to his knees with no shoes that we were not going to jive..... I just don't know how I am going to handle him next time we are out there. I know he will come up to us and my temper is just so hard to handle sometimes!! I have decided that I will just be as cordial and straightforward as possible without raising my voice and that I will be as nice as I can be to his wife. I feel very sorry for her and for his 2 little kids. There really is nothing to argue with him about- the covenants are the covenants and he agreed to them, period. So, I just hope he isn't more crazy than I am estimating. I am usually very good at reading people and I think we can handle this guy...........
