Who Represents You?

One of the hot topics facing the world of real estate right now is the issue of agency. Some would have you believe that it really doesn't affect you, the buyer, and that nothing much has changed. But they are wrong.

The topic of agency is important to you because it answers the most basic and fundamental question that can be asked of any real estate professional: Who do you represent in this transaction?

Until that question is answered, you may be left with the impression that all agents who work with buyers actually represent those buyers, and that you have somebody going to bat for you in this transaction. Well, the issue of agency is important because without it, we can never be sure who represents who.

Here's the scenario:

You meet a really nice agent at an open house named Bonnie. Even though Bonnie's house is not right for you, she tells you she has others to show you that fit your needs exactly. You spend an hour or so with Bonnie looking at a half dozen homes and talking about your needs and your wants. During the course of the conversation, you volunteer that you have $100,000 cash to spend and that you will not go over $100,000 purchase price no matter what. Then you find the perfect house. Asking price is $100,000 but you decide to offer $92,500 based on recent sales in the area. During negotiations, the seller asks Bonnie directly how much cash you have and how high will you go? What does Bonnie say?

Here's the answer: Unless you have signed a "Buyer Agency Agreement" with Bonnie making her your buyer agent, she is most likely acting as a sub-agent to the listing broker who represents the seller. If that is the case, she has a fiduciary obligation to the seller to disclose to him any information she has that might "promote or protect his interest" in the transaction. Guess what? Bonnie has that information.

The Seller, now having knowledge of your financial position, counters at a full $100,000. He knows you can afford it and that this price falls within your desired range. He also knows that you have seen a number of other homes and that his is the one you want.

Regardless of what eventually happens in this scenario, it can hardly be called an even playing field. So, how can you protect yourself from a possible disclosure required of a seller's agent?

1. Make sure that the agent you are working with has agreed, in writing, to represent you as a "Buyer's Agent." This will mean signing a buyer brokerage agreement in which you promise to work only with that particular agent for a specific period of time, often 90 days. It also means that you promise not to buy from anybody else, even FSBOs, without involving your buyer's agent. In almost every case, the commission will still come from the seller, but your agent must present the offer.

2. Never say anything to anybody unless you would be willing to have that information repeated into a seller's ear. Assume that everybody, and I mean everybody, is working for a seller unless you have specifically hired them to work for you. And even then, be discreet. During the second world war, the military promoted a phrase designed to stop idle gossip: Loose lips sink ships! You would do well to adopt that philosophy in your home-buying as well.

How Much Can You Afford?

As you think about applying for a home loan, you need to consider your personal finances. How much you earn versus how much you owe will likely determine how much a lender will allow you to borrow.

First, determine your gross monthly income. This will include any regular and recurring income that you can document. Unfortunately, if you can't document the income or it doesn't show up on your tax return, then you can't use it to qualify for a loan. However, you can use unearned sources of income such as alimony or lottery payoffs. And if you own income-producing assets such as real estate or stocks, the income from those can be estimated and used in this calculation. If you have questions about your specific situation, any good loan officer can review the rules.

Next, calculate your monthly debt load. This includes all monthly debt obligations like credit cards, installment loans, car loans, personal debts or any other ongoing monthly obligation like alimony or child support. If it is revolving debt like a credit card, use the minimum monthly payment for this calculation. If it is installment debt, use the current monthly payment to calculate your debt load. And you don't have to consider a debt at all if it is scheduled to be paid off in less than six months. Add all this up and it is a figure we'll call your monthly debt service.

In a nutshell, most lenders don't want you to take out a loan that will overload your ability to repay everybody you owe. Although every lender has slightly different formulas, here is a rough idea of how they look at the numbers.

Typically, your monthly housing expense, including monthly payments for taxes and insurance, should not exceed about 28 percent of your gross monthly income. If you don't know what your tax and insurance expense will be, you can estimate that about 15 percent of your payment will go toward this expense. The remainder can be used for principal and interest repayment.

In addition, your proposed monthly housing expense and your total monthly debt service combined cannot exceed about 36 percent of your gross monthly income. If it does, your application may exceed the lender's underwriting guidelines and your loan may not be approved.

Depending on your individual situation, there may be more or less flexibility in the 28 percent and 36 percent guidelines. For example, if you are able to buy the home while borrowing less than 80 percent of the home's value by making a large cash down payment, the qualifying ratios become less critical. Likewise, if Bill Gates or a rich uncle is willing to cosign on the loan with you, lenders will be much less focused on the guidelines discussed here.

Remember that there are hundreds of loan programs available in today's lending market and every one of them has different guidelines. So don't be discouraged if your dream home seems out of reach.

In addition, there are a number of factors within your control which affect your monthly payment. For example, you might choose to apply for an adjustable rate loan which has a lower initial payment than a fixed rate program. Likewise, a larger down payment has the effect of lowering your projected monthly payment.
