A good thing about Dolton is that the cost of living is reasonable. You won't have to spend a fortune to buy a home. The downside is that the crime rate is a lot higher than it could be. Chicago is pretty close and you will have a lot of options for finding work or going back to school for night classes or an IT certification for example.
On the bright side, Dolton is just a couple of minutes from Lake Michigan. In the summer, there is a lot you can do for fun in the area. The lake is always a great place to visit and there are a number of parks immediately in Dolton as well.
If you like to go shopping, Dolton has a lot of local stores that should take care of most of your needs. There is a public bus system you can utilize, but it doesn't cover all of the shopping areas. Having your own car will make getting around a lot easier.
