Does Interest-Only Really Cost Less?

One of the fairy tales borrowers frequently hear is that a loan carrying an interest-only (IO) option is priced better than the same loan without the option. It is a fairy tale because the IO allows the borrower to avoid paying down the loan balance, which makes it riskier to the investor -- and greater risk should mean a higher price.

At the wholesale level, where prices are extremely competitive because they are directed to mortgage brokers, the IO version of a loan always carries a higher price than the same loan without the IO option. Sometimes the price difference is small, sometimes it is large -- but I have never seen IOs priced lower.

Anything Can Happen

Yet in the bazaar-segment of the retail market, where borrowers deal one-on-one with mortgage brokers and loans officers (collectively "loan providers"), anything can happen. A trusting borrower without knowledge of competitive prices, dealing with a sales-hungry loan provider, could be told that the IO was priced better. The purpose of the fairy tale would be to move the deal forward. Here is an example:

"I read your postings on interest-only loans, but it didn't seem to apply to my situation. My broker gave me the option of a 30-year fixed-rate mortgage at 6.125 percent, or an interest-only (first 10 years) with a fixed 30 year rate of 5.875 percent. My plan was to take the interest-only but make the larger payment that I would have had on the amortizing loan. This should save me money..."

I don't have any facts other than those in the letter above, and can only speculate about the source of the misinformation. Perhaps the most plausible explanation is that the 6.125 percent rate was simply concocted out of thin air to make the 5.875 percent rate on the IO look good. A borrower who gets all his information from a loan provider is vulnerable to such chicanery.

A second possibility is that the IO is on an adjustable-rate mortgage (ARM), rather than a fixed-rate mortgage (FRM), as the borrower was led to believe. ARMs typically are priced lower.

Leaving Out Other Charges

A third possibility is that both rates are correct but the loan provider left out other loan charges, including points. As an illustration, I went to an online site and priced a 6.125 percent 30-year FRM against a 5.875 percent IO version of the same loan. Both loans were there, but the second cost 2.3 points more than the first.

A final possibility is that the loan provider was "low-balling" the IO rate and had no capacity to deliver the 5.875 percent quote. The market changes every day, and loan providers can't be held to quotes until they are locked. Between the quote day and the lock day, they can choose from a wide selection of explanations as to why the rate is higher, including a general change in the market and a reevaluation of the borrower's credit.

The upshot is that borrowers cannot be confident that loan providers are giving them reliable information about price differences between different loan options. Many loan providers will, but some will exploit the borrower's ignorance for their own benefit.

    Interest only may look attractive but will cost much more in the long term. If you have a IO mortgage, considering opening a Mortgage Savings Account before refinancing. You may be able to pay your mortgage in full in 5 to 10 years and save hundreds of thousands of dollars in mortgage interest without refinancing fees. Google "Mortgage Savings Account" or research www.maxhouse.com to educate yourself!

    Thank you Roman. I have been a mortgage consultant for 8 years and have seen the good, the bad, and the ugly in this industry. there are quite a few ppl out there that get there facts mixed up and don't take the time to listen to the broker. all thier interested in is hearing the best rate and the best terms. and often combine the two. thats why it's our job to make sure they understand clearly the loans available to them. It's a brokers job to make sure they educate the borrower and take time to explain in detail what the borrower is getting into. and to make suggestions to them based on thier individual needs, and plans for the property thier buying. The IO works great for someone that is planning on selling during the interest only period of the loan, or may have a large sum of monies comming to them durring that time ( retirement or inheritance). but if they plan on staying in the property longer than the IO period they will be taking a little risk, but not much if the IO period is 10 yrs. A great book to read about IO loans is " millionaire Mortgage Planner" by steven marshall. and NO I don't get ahything from telling you that, it's just a good book with a different perspective on those loans. The biggest problem in our industry is the money hungry loan officers that are in it for a quick buck. they give al of us brokers a bad name. Not all of us are out to see what we can make off of each deal. some of us are here for the long haul and depend on repeat business and referrals from past clients. I have several clients that I have done several loans for. And for thier family members and friends. Yes as silly as it may sound, some of of do care about our clients and thier financial sittuation. And getting them into the right loan.

    Terrible article with no home work. IO's do have lower rates, but are indeed riskier to the borrower usually in 4 or 5 years when the rate adjust THEN- but it is fixed for now so that he/ she can buy more house then they can afford or at least document. No one talks about the millions of legal workers who work under the table and are unable to document the income. IO's help these people who make legit payments.

    Are the homes in Forecloser at this Mortgage crisis taking place, are they mostly ARM mortgages?

    Assuming you found an IO costing the same as Non-IO, and, assuming you don't care much about building an extra equity from paying off the pricipal portion, then, at least, you can take an extra deduction for income tax.
