For most people, a house is the biggest purchase they will make in their lives, one they will pay off for years, even decades, to come. But spending too much on a house could leave you with little money for other goals in life, such as retirement, college funds and vacation.

Before beginning a house hunt, you must first decide whether renting or buying makes the most sense.

If you’re a renter, keep in mind that your rent will go up over time. Renters usually rent if they know or like the idea that they can move when and if they like. Also, renters usually do not have to pay for the maintenance, lawn care or home repairs. They also don’t have to put sweat equity into the rental.

If you buy, know that you’re committed to years of fixing anything that breaks in the house, manicuring the lawn, and paying for any major repairs. Renting makes sense if you plan to live somewhere for a relatively short period of time, as the costs associated with buying a home — such as escrow fees, taxes and closing costs — take some time to amortize. If you’re planning to remain in a place for a longer period of time, buying a house is usually the way to go (however, this equation changes with home values in your area, employment trends and several other factors). Even though the market may fluctuate, over a long stretch you’re likely to make money. And as the real estate market has shown us in 2007 and 2008, it can be a bumpy ride.

If you’ve decided that home ownership is right for you, the next step is deciding how much home you can afford. Typically, most lenders suggest that you spend no more than 28% of your monthly income on a mortgage. Try calculators from dinkytown.com or Bankrate.com to find out how much you can afford. Keep in mind, in addition to the mortgage costs, you’ll have to pay the closing costs and legal fees, which are usually 2% to 3% of the house price. Also, don’t forget moving fees and labor, and any fixes that you might have to make to the house upon moving in, plus monthly maintenance fees if you’re moving into a condo or planned community.

When you’ve figured out your price range, take a look at the market and the issues that matter to you. Research school districts, crime statistics, impending construction or anything that could decrease or increase the value of a home. Look at the surrounding area to see if it’s a place in which you see yourself and family. You can research at greatschools.net or Zillow.com.

When you’ve chosen a home to bid on, don’t assume that the selling cost is the actual cost of the house. While real estate agents use comparable houses, or “comps” as way to price a house, consider what it might cost to buy and build a home on piece of land in that area. For a thorough assessment, hire an appraiser. You can even search zip codes online at AppraisalInstitute.org.

If you have the cash to buy and upkeep, go ahead and buy a home. It’s an investment that will grow over time.
