My two cents, for what it is worth:
You move into a house with a yard, you have yardwork to do. Period. Now, it is fine to pay someone, either on your own or through condo dues, but it must be done. Shoveling snow at 6:30 am does seem a bit extreme, but I have the luxury of being able to inform my office that I will get there when I get there. After many years of snow shoveling, I can tell you that it is much better to get the nasty white stuff up while it is still fresh and fluffy. Even if you don't get ice formation, the snow can melt just enough to get wet and heavy.
It's not like you are going to be shoveling the whole driveway by yourself. You'll have Tom helping you.
As for the summer work, I hate grass. I hate watering it, I hate fertilizing it, and most of all, I hate mowing it. Even so, I mow once a week in spring, and maybe once a month during summer droughts. (I refuse to waste good water on mere grass.) Like shoveling snow, the job is much easier if you keep up with it. It's even easier if you use a good self-propelled lawn mower equipped with a mulching blade, but that another thing.
It is much easier than trying to maintain a wildflower meadow, because unless you regularly weed and care for it, the wildflower meadow gets infested with very unattractive weeds that spread all over creation. Been there, done that, had to spray the mess with Round-up. Still do, actually.
You are, however, excused from helping with the flower and vegetable beds next door. It would be nice to help with the vegetable garden if you are getting any of the vegetables.
As for the neighbors leaving manure and car parts next to your yard: as another poster pointed out, why shouldn't they? By not taking care of the yard, you show that you don't care.
