Rock-bottom mortgage rates may be gone for good.  This week’s Freddie Mac Primary Mortgage Market Survey shows in numbers what rate shoppers have learned the hard way — mortgage rates are spiking.

During the 7-day period ending November 18, the average 30-year, conforming fixed rate mortgage jumped to 4.39 percent, an increase of 0.22% from the week prior.

And it’s not just rates that are soaring. The average number of points charged to consumers increased to 0.9 percent last week. For most of the year, that cost had been 0.7 percent.

One “point” is equal to 1 percent of your loan size.

With the sudden rise in mortgage rates, we have to question whether the Refi Boom is ending. Between April and early-November, conforming mortgage rates dropped more than a full percentage point and, during that time, a lot of homeowners capitalized on the market. Refinance activity was strong; rates cut new lows each week.

Today, however, Wall Street sentiment is different. There’s a growing concern for the future of the U.S. dollar, and that’s making mortgage bonds less attractive to investors. As demand drops, so does the underlying bond’s price which, in turn, causes mortgage rates to rise.

Buy-sell patterns like this are common. The speed at which they’re changing is not.  Mortgage lenders can barely keep up with the volatility, issuing up to 4 separate rate sheets in a day.

Therefore, if you’re shopping for mortgage rates, or wondering whether it’s finally time to join the Refi Boom, the time to lock is now. Mortgage rates should remain volatile through the New Year, at least. At what level they’ll be then, though, is anyone’s guess.

Mortgage markets stalled last week in back-and-forth trading as Wall Street grappled with weak housing data, falling builder confidence, and worsening jobs numbers nationwide.

Because markets were volatile, rate shopping was challenging.

Conforming mortgage rates did managed to make a new all-time low last Thursday but quickly gave up those gains. Most of Friday afternoon was spent in the red and, as a result, for the second straight week, mortgage rates failed to fall overall.

But, although last week’s action puts a damper on this summer’s mortgage rate rally, the Refi Boom is still going strong.

According to Freddie Mac, as compared to April 8 when mortgage rates touched their recent high-point, pricing is hugely improved across 3 popular loan products.

• 30-year fixed : Then, 5.21%; Now, 4.42%
• 15-year fixed : Then, 4.52%; Now, 3.90%
• 5-year ARM : Then, 4.25%; Now, 3.56%

As an example of potential savings, a homeowner with a $250,000 30-year fixed rate mortgage would save $96 per month at today’s rates as compared to April’s. 

Over the life of a loan, that’s a savings of $34,560.

This week, it’s unlikely that the Refi Boom will meet its end, but that doesn’t mean you should wait for rates to fall further. Mortgage rates tend to change quickly and without notice, and should rates rise, you may find that you’ve missed the market bottom.

If today’s rates appeal to your finances and budget, consider locking something in and moving forward.

No doubt you’ve heard that mortgage rates are low. They’re lower than they’ve ever been in history.  The news is everywhere.

Just check out some of these headlines from the last 24 hours:

• Mortgage rates set new lows for the 6th straight week (Reuters)
• Mortgage rates fall again; 30-year fixed at 4.54% (Wall Street Journal)
• Mortgage rates hit another low : 4.54% (NPR)

Fixed mortgage rates are now down more than 1/2 percent from the start of the year, and 3/4 percent from just 1 year ago. The drop has dramatically improved home affordability for home buyers while creating refinance opportunities for existing homeowners.

From a payment perspective, a conforming, 30-year fixed rate mortgage is now cheaper by $41.94 per month per $100,000 borrowed versus July 2009.

A homeowner with a $300,000 mortgage, therefore, is saving $45,295.20 over 30 years.

Low mortgage rates rarely last long and rates appear to have troughed. After a big downhill between April and July, they’re now flat. This could mean rates have finished falling, or that they’re gearing up for another drop lower. Either way, if you haven’t talked to your real estate agent about home affordability, or your loan officer about refinancing, it may be time to make that call.

If today’s market marks the end of low rates, rates are expected to rise quickly.

Mortgage markets improved last week as economic data revealed a slowing U.S. economy.

Major stock indices fell to 2010 lows in response to a weak jobs report among other data points, forcing worldwide investors into the relative safety of U.S. government-backed bonds.  This category includes mortgage-backed bonds and the extra demand helped to drop rates.

Once again, mortgage rates improved and Freddie Mac is reporting new all-time lows on three popular, conforming loan products:

• The 30-year fixed rate mortgage
• The 15-year fixed rate mortgage
• The 5-year adjustable rate mortgage

Low rates mean low payments and you can’t know your options until you ask.

This week, mortgage rates may move slowly. There’s very little data set for release because markets were closed Monday in observance of Independence Day, and because the second calendar week of a month is traditionally data-slow.

Tuesday, a consumer confidence study is published; Thursday, jobless claims plus consumer credit levels hit; and, Friday, we’ll see wholesale inventories.  That’s about it.  None of these reports are particularly important but, in aggregate, the numbers can show whether the economy is expanding or contracting.

In general, evidence of an expanding economy should cause mortgage rates to rise.  In a contracting economy, rates are likely to fall.

Actual mortgage rates will vary by borrower, based on property type, credit score, and home equity, but if you haven’t talked to your loan officer about a refinance into today’s rates, it’s likely worth the time for a phone call.  Once mortgage rates start to reverse higher, they’re expected to reverse quickly.

You’ll want to act before that move occurs..
