I imagine rental condos/apartments tend to be in or around cities, whereas houses tend to be in suburban/rural areas. A one bedroom condo/apartment in/near Concord/Manchester might run $700-$825.
There are plenty of nice neighborhoods just outside Manchester city (5-15 minutes drive to the city) where a couple could rent a decent apartment. I recommend a particular no-lease rental property located off Front Street that might fit your bill. (Forum rules prevent me from mentioning the property name here.)
Obviously, it is difficult to state
average expenses, but here are some expenses for a fairly disciplined couple I happen to know very well:
* Electricity: $35 with two computers and one LED monitor that tend to run about 16 hours a day
* Heat: Most apartment rents include heat and hot water. Rental houses tend not to include heat or hot water.
* Amount taken out of paycheck: FICA, federal income taxes. No state/county/city deductions are made.
* Cable: $0-$30-$50-$100 depending on taste
* Internet: $40-$70 depending on quality of service
* Car insurance: $300 a year with decent coverage on an older car for two drivers with good history
* Groceries: Hard to be specific, but it is useful to know that living outside the city means you might need to drive 3-5 miles to get to a grocery store. Gas generally costs slightly higher than US average.
I recommend using an online tool to compare cost of living.
Cost of Living Calculator: Compare the Cost of Living in Two Cities - CNNMoney is one such tool.
