As a growing number of economists, pundits and real-estate professionals assure us the housing market’s worst days are over, prospective home buyers need a trusted advocate to make sure they don’t end up on the wrong side of someone else’s trade.

More often than not, that person will come in the form of a real-estate professional working on the buyer’s behalf and earning a commission for their trouble. Below are 5 simple questions you can ask to gauge whether a given candidate is looking out for your best interests – or his or her own.

But first, a word on terminology.

The terms “agent,” “broker” and “realtor” are often thrown around interchangeably. This isn’t exactly right. While laws differ from state to state, acquiring a broker’s license typically requires a series of courses on real estate practices, principals, finance, law, appraisal and the escrow process. A broker can use his license to form a brokerage, and the company can then perform services as a licensed entity.

In many states (like California) a licensed broker can not only conduct real estate transactions, but earn commissions for arranging mortgages and other types of real estate-related loans. For this reason, a brokers license offers the holder huge potential earnings power.

An agent is a step below a broker. While requiring a license, an agent is normally treated as an employee of the broker and thus the broker is responsible for the actions of the agents under his charge. If an agent screws up, his reputation (and license) as well as his broker’s is on the line. Agents can typically conduct the same transactions as a broker, but must do so under the supervision of their boss.

Finally, the term “Realtor” is used to specifically identify a real estate broker or agent who is a member of the National Association of Realtors, or NAR. The NAR is a nationwide trade group that collects member dues, lobbies in Washington and runs marketing campaigns urging Americans to buy homes. The NAR is conspicuous in its role as national housing cheerleader, as it’s chief economist Lawrence Yun has been predicting an imminent bottom in prices since early 2006.

1. Is it a good time to buy?

Of any question a buyer is likely to ask his broker (or agent), this may be the first. And the most important. The answer itself isn’t nearly as important as how the broker responds.

Any broker that says definitely that yes, this is a great time to buy, should be eyed with skepticism. Without knowing a buyer’s specific circumstances, understanding localized market trends and the underlying value of a specific home, saying it is a great time to buy is a sales pitch, pure and simple.

Brokers will often cite low interest rates, high levels of affordability, low replacement costs and home prices that have fallen precipitously from their peaks as reasons its never been a better time to buy. But ask yourself, all those conditions were true six months ago — was it a great time to buy then?

The proper response to this question from a responsible broker is to answer the question with a question, or questions. How much money have you saved? How long do you plan on owning the home? How much money do you make? How much is your other debt service? What are your contingencies if you lose your job? How is your credit? What are your other motivations for wanting to buy?

Only armed with answers to these and other questions can a broker — or a buyer for that matter — determine whether its the right time to buy.

2. Are home prices near a bottom?

As with the previous question, the answer should be in the form of a question. Where and when are you looking to buy? Do you want a move in ready home or one that needs some work?

While there is no crystal ball as to the direction of home prices in the near or long term, a broker should have a clear understanding of the dynamics effecting his or her local market. I hear ad nauseum here in California that home prices are stabilizing because demand is up, prices are down and homes are receiving multiple bids. But those are external symptoms of market machinations underneath the surface.

Foreclosure moratoriums put in place late last year limited the number of bank owned homes dumped onto the market. This constricted supply, and coupled with tax incentives, low interest rates and aggressive marketing from the NAR, led to a situation where in some areas, for some homes, demand outweighs supply. But that doesn’t mean the situation will persist — in fact, the smart money is betting it won’t.

This dynamic is far from ubiquitous, as most high end markets remain illiquid with prices tumbling into an apparent vacuum.

Real estate is, and will always remain, local.

3. How do you determine which homes to show me?

Not to beat a dead horse, but this question should be met with yet another series of questions. What size home are you looking for? Are schools important to you? How close do you want to be to public transportation? Do you care about being within walking distance to shops and restaurants? What style of home do you like? Do you want a yard?

A good real estate broker should be a blank slate, absorbing your preferences, desires and reasons for buying without injecting his own bias. Just because your agent loves a certain home and thinks its a great buy, doesn’t mean it fits your criteria. Don’t be afraid to tell your broker that you don’t like a particular home.

Brokers should show you a variety of homes, below, within and above your price range, to give you a sense of what is out there on the market. With prices still coming down in most areas, you may walk inside your dream house and decide its worth it to keep renting — and saving — for another year until prices fall to something you can afford.

Until you feel comfortable your broker is showing you everything that may fit your criteria, perform your own searches on the myriad free websites out there. Redfin.com is a great resource for the metropolitan areas it covers, while Trulia.com, ziprealty.com and even Realtor.com have excellent free search features.

4. What are my financing options? How much can I afford?

While real-estate brokers are often legally allowed to arrange loans, more often than not its a dicey legal proposition for the broker to sell you a house as well as a mortgage.

Nevertheless, brokers should be well-versed in available financing, rates, qualification requirements and whether sellers require a mortgage pre-approval letter to accompany any offer (these days, most do). If your broker doesn’t know the answer to a certain question, that’s OK as the rules change almost daily, but he should actively pursue the answer and report his findings back without too much delay.

Shopping around for the best loan terms can be a time consuming and confusing process, but it must be done. Gone are the days where Wells Fargo (WFC) always gave you the best rate, or your buddy down at Chase (JPM) could get you a great deal. Keep in mind most loans these days are originated to Fannie Mae (FNM) and Freddie Mac (FRE) guidelines, which means most big lenders offer similar loan programs.

All things being equal, choose a lender you feel you can trust (not just the one offering you the best deal) and always have a backup.

Lastly, never trust a broker to “tell” you how much you can afford. This decision, especially in an environment where home prices are likely to fall for the foreseeable future, should be one each buyer must make for himself.

Plans change, life doesn’t always follow the path you hope it does. Being conservative in what you can afford, leaving a cushion and planning for the unexpected are paramount in today’s uncertain market conditions.

5. Provide me with examples of a few closings you are the most proud of over the past year.

This question gives your broker a bit of an opening to sell himself, and will go along way towards helping figure out whose side he is actually on. If your broker launches into a a story about this cute young couple he helped get into the house of their dreams, move along, cute young couples rarely make savvy home buying decisions and are easy prey for aggressive brokers. Also pass if you hear things like, “I found this great house right when it came on the market, we jumped at it and got in before the other buyers had a chance to bid.”

Sellers, by and large, are still unrealistic about how much they can sell their homes for. This means that when houses come out onto the market, the asking price is nearly always above where it will actually go for. Be patient, make your broker work for his money.

Although there are situations where multiple bids will come in from prospective buyers, chances are this isn’t a house you want to buy. Most of this sort of activity is going on in areas with high levels of foreclosures. Now that the moratoria are lifted, banks will start flooding the market again come next month. All that great news about limited supply will become ancient history as prices plunge once again. The house itself may be great, but just because homes are “cheap,” doesn’t mean they won’t get cheaper.

A good response is one where a broker tells you a story of a buyer he worked with for months, go to know a few neighborhoods that fit all the pertinent criteria, and waited for the right house to come on the market. Many sellers will list their house at a “hopeful” price for the first 30 or 45 days, then drop it down to something more reasonable. Rarely will a house sold in the first couple weeks be a “steal” for the buyer.

Your broker should stress that patience, research and shrewd negotiating got his client a great home at a great price.

To be sure, there are other questions to ask of a prospective broker, but this is a good start. Finding a broker should be treated like a job interview, after all, even though the commission may not be coming out of your pocket, you, as the buyer, end up paying one way or another. Make sure your broker is worth his salt.
