Most Common Home-Buying Mistakes:

1. You didn't set a budget.
Buy a home that's way out of your price range and you could well derail your ability to fund other important items such as retirement savings, your kids' education -- not to mention an entertainment budget.

Mortgage brokers will tell you how much you can borrow. But that amount may not be what you can afford to pay.

"What if you have a lot of kids or you like to travel a lot?". "You've got to ask 'How is this housing purchase going to affect our monthly spending?' You have to look at all of your monthly expenditures."

2. You picked the wrong mortgage.

These days, many homebuyers are rushing to secure a mortgage as fast as possible without fully exploring their options. That's because sellers often only consider bids from individuals who have been pre-approved for a loan. A word of advice? Pick your financing package with care.

First-time home buyers may qualify for a program through Fannie Mae that requires lower down payments and easier qualification limits than standard loans.

3. You picked the wrong community.
Some places are just flat-out expensive, and you'll probably have to search for a location that's affordable. That doesn't mean you should choose the cheapest locale.

If you don't like the location you'll be unhappy. What's more, you'll probably have a hard time selling your property if the community isn't good. Ask around and read the local papers to know how the community is faring economically, what the major issues are, how many resources it offers.

Don't neglect the schools. Gather such data as test scores, statistics on the percentage of kids who graduate and go to college, the student/teacher ratio and so on. Talk to parents and students to get the inside scoop.

4. You didn't know what homes really cost.
The best way to determine if you're getting a fair deal is by comparing the cost of the home you're interested in with similar homes in an area. You can do this easily by having your Realtor provide you with a CMA (that's short for Comparable Market Analysis). A CMA lists such things as addresses of recently sold homes, prices, date sold, the number of bedrooms and bathrooms and -- ideally -- such things as the home's condition, its size and extra features.

5. You used a bad real estate agent.
Don't make buying a home more difficult by choosing the wrong agent. You want a buyer's agent who works for you and understands your needs and financial limitations.

References from friends can help you find a good pro. Interview three, and ask to see their activity lists, which reveal every property the agent sold (or whose clients bought) in the past year. Look at sales prices. Make sure the agent has significant experience in the area where you want to live and the price range that you're looking for.

6. You never went back to check on the neighborhood.
If you're like most homebuyers, you probably spend many weekends looking for a new dwelling. But what happens to the neighborhood on weekdays or after dark? Is the house that's "convenient to town" sitting on a main thoroughfare that fills up with cars come commute time?

The only way to answer these questions is to go back and see what the neighborhood's like at various times of the day and week. Do your neighbors spend weekends with the stereo blaring? You want to know as much about the neighborhood as possible before you buy.

7. You forgot to consider resale.
It's easy when you're house hunting to forget what it's going to be like to sell your home down the road. But as you tour homes, put yourself in the perspective of the sellers. You may be drawn to a home that has quirky features or no closets or just one, tiny bathroom (You can use armoires. Share showers.) But others may not be as enthusiastic. When you buy, think about the day it comes time to sell.

8. You bought the most expensive home on the block.
It's wonderful when you find your dream house, but if it's the most expensive home on the block you could have a problem. Quite simply, your neighbors' lower home values will dampen yours. Remember, people who buy a $500,000 home usually want to be surrounded by other $500,000 homes, not tiny $100,000 bungalows.

9. You didn't do an inspection.
Bottom line: you should never buy a home without having it inspected. After all, you don't want to learn that you've bought a house that's filled with termites or has a frazzled electrical system. If you're building a new home, an inspection can ensure that all the work has been finished properly.

Home inspections typically run $300 to $600 and usually include a check of a home's heating and air condition systems, plumbing and electrical works, roof, walls, foundation/structure, drainage, the garage and basement.

Underground heating oil storage tanks also should be inspected before you buy since leaking tanks cause huge environmental, legal and financial problems. (A seller's disclosure statement should reveal if there's an underground tank on the property.) The Environmental Protection Agency has tank guidelines for homeowners -- plus contacts at state Department of Environmental Protection offices -- so you can find pros to help.

10. You forgot about closing costs.
Think it's bad to pay tax when you eat out? Wait until you're paying closing costs, which can run up to 5 percent of the home's purchase price.

A mortgage lender should provide you with a specific estimate of what costs will be. But keep in mind they include such things as origination (points) on a loan, escrow fees, title and homeowners insurance, legal costs, property taxes, fees to record your need deed and notary fees.

11. Not getting what you want because you're impatient.
This is a big decision. You need time. Impatient decisions can lead to mistakes.

12. Trying to make a shrewd investment.
People need to buy based on what fits their family. Don't try to guess what will happen to the market.

13. Not buying at all.
If you can afford a home and you don't make that purchase, you'll lose the benefit of tax deductions, building home equity and the appreciation in value.
