I live outside of houston with a family of 5 and this is my rundown of bills, etc
1. House rent (3 beds/2baths on 1 acre)- $800/month
2. Food- $600/month (cooking at home, my family eats out maybe twice a month)
3. Utilities- Electric- $280/month, water- free (my house runs on well water), gas (my house is electric)
4. Car insurance- there are so many insurnce agencies where you can pay as little as $40-60/month for two drivers & two cars but it can go as high $120/month
Car payments- again so many buy here/pay here places and you can make instalments for as little as $60/week for a descent family car or $80-100 for a SUV/Truck
5. Public schools are free, Daycare (up to 5 years old) can run you anywhere from $100/week to $200/week. There are many private schools and each one varies, but some offer financial aid
6. rental insurance- $30-50/month, Fuel- each fill up $30-$100 (depending on vehicle), Cable/home phone/internet- $100/month (AT&T), Cell phone service- $50 unlimited (Boost Mobile)
If you rent an apartment water/sewer/garbage is usual included in the rental price. Renting a house all those costs are normally on you. Utility Bills will vary depending on the are you live in, because some areas have several electric companies and some areas only have one electric company. Some of them will include gas prices, others won'ts and you'll have two seperate bills.
Your price of rent will also vary greatly by the area you live in, I live outside Houston in the country so my rent is realitively cheap, downtown Houston you can look at paying at least $1200 for a nice 3 bedroom aprtment. There's a couple very nice areas outside Houston (kingwood, humble) where you can get a 4 bedroom house for around $1200/month.
Something you might want to check into is contacting a real estate agent and telling them what you are looking for in housing and what kind of area you want to live in and there are many of them that will be able to find you a rental property in an area you want.
