You are ready to buy when…

1. You have a budget -- and you know how to use it. Owning your own place comes with a slew of new expenses, so good money management skills are must-have number-one. If you don't have a household budget right now, start one. (See Build Your Budgetto learn how.) You need to know where you are financially -- where your money is coming from and where it goes every month -- to know exactly how much you can afford to spend on a new home.

Once you have your current finances sorted out, draw up a mock budget for homeownership. Find out how much homes cost in your area and how much your mortgage payment will run. Then, factor in higher utility bills, homeowner's insurance, property taxes, homeowners association fees, and maintenance and upkeep costs, as well as higher commuting costs if you're considering a neighborhood further from work. If you simply cannot afford the increased expenses that come with a house, it's never a good time to buy -- not matter what's happening in the real estate market.

2. You have a sizeable down payment. Traditionally, to get your foot in the door, you'll need a down payment worth 20% of the home price. That means for a $250,000 home, you'll need $50,000 upfront. Sure, there are ways to get around that steep requirement with zero- or low-down loans, but those options will cost you. You may have to pay extra for private mortgage insurance or take out a piggyback loan with a much higher interest rate. With the slowing housing market, having that 20% down payment becomes even more important because you'll start off with some equity in case you have to move earlier than expected." In the early years, you aren't building any equity with the mortgage payment," says Eisenberg. "If the market changes or your personal circumstances change and you're forced to sell, you could lose money" if you made little or no down payment. The equity in your home can also give you an extra source of cash in an emergency. See Why You Need a Down Payment to learn more.

And the money down is only the beginning. Don't forget to factor inclosing costs (3% to 6% of the purchase price) property taxes, initial repairs, moving expenses and decorating costs.

3. You have a reliable source of income. Buying a home is along-term financial commitment, so you'll need consistent cash flow to cover those monthly payments -- not to mention the little extra expenses that come with homeownership. If you're in school, plan to go back to school, have a less-than-reliable job or plan to start a family, you need to take a good look at your future cash flow abilities. Will you be able to make your mortgage payment six months from now? How about six years from now? "Some couples can afford the house when they're both working, but if a kid comes along and one wants to stop working, then they have a problem," says Eisenberg.

4. You have an emergency savings fund. If you have enough cash on hand to cover three to six months of your living expenses, you're one step closer to being prepared for homeownership. Just incase something happens to disrupt your steady income -- say a serious illness, unexpected layoff or even a natural disaster that prevents you from working -- you want to make sure you can still afford to make your mortgage payments until you can get out of your rough patch, says Bob Baldwin, a CPA in Charleston, S.C.

5. You have your debts under control. Call 'em crazy, but lenders like to make sure you'll have enough money each month to pay your obligations. So before they'll give you a mortgage, they take a look at your so-called debt-to-income ratio. Generally speaking, they want to make sure your monthly housing costs -- including principal, interest, taxes and insurance -- will consume no more than 33% of your monthly gross income; and that your total debt payments, including your mortgage, credit cards, student loans and auto loans, will remain below38% of your total pay. So if you have large outstanding debts, it's a good idea to try to pay them down before applying for a mortgage to make sure you can qualify for as much money as you'll need. This also means you should avoid taking on any substantial new debt six months to one year prior to your purchase, or you may throw your ratio off. So, it may be best to drive that clunker for a little while longer, or put off charging that European vacation. Find out how much you can qualify to borrow.

6. Your credit report is in good shape. Nowadays you don't have to have perfect credit to become a homeowner, but a decent history can help you get a lower interest rate on your mortgage and a lower monthly payment. The government allows you to check your credit history free once a year from each of the three main credit bureaus at AnnualCreditReport.com. So take a peek to find out what lenders see about you. If you see any errors, correct them now. If you see room for improvement, find out how you can boost your score."Don't be sloppy the year or two before you buy the house," says Baldwin. You don't want any missed payments or other black marks that could lower your estimation in the eyes of lenders.

Having bad credit, however, may not be your biggest concern. If you're just starting out, you need to make sure you have a credit history. If you hold a credit card or took out student loans, you're probably covered. If not, find out how you can build a stellar credit history from scratch, preferably one year or more before you plan to buy.

7. You can make a long-term commitment. Are you ready to stay put for at least three to five years? Typically, that's how long you'll have to keep the house in order to recoup your buying and selling costs. If you sell before then, you may lose money on the deal. And if you do turn a profit, you'll have to pay capital gains taxes if you lived in the house less than two years. The length of your stay becomes even more important now that home appreciation is beginning to slow from its previous pace. If you don't think you'd stay put for that long, you may be better off renting.

Don't fret: Renting can actually make better financial sense for some people at different times in their lives, says Eisenberg. If you think you may get a job transfer, go back to school or otherwise need to move within the next five years, renting gives you the flexibility you need and could possibly save you money.

Want to find out if renting or buying makes the most sense for you? Our calculatorwill crunch the numbers to help you decide. In the slot for "appreciation rate," assume your home will appreciate at the rate of inflation or a little more, just to be safe. Right now, that's around3% to 4% annually.

8. You are prepared to become your own landlord. Even if you can afford homeownership, don't buy simply because you can. You need to make sure you're ready to live the lifestyle. Owning a place comes with a fair share of new responsibilities, headaches and costs -- not the least of which is becoming your own landlord. When you rent an apartment, you simply call the landlord if something breaks. With your own home, if it's broke, you fix it -- or you'll have to pay someone else to fix it. You're also responsible for upkeep, including yard work and shoveling snow (unless, of course, you buy a condo without a yard). Will you have the time, energy or desire to maintain the property? How about the money for all those little extras, such as buying your own lawn mower and hiring the occasional plumber? Make sure you know what you're getting into.
