It’s not just 30-year fixed rate mortgages that are posting all-time lows these days. The 15-year mortgage has been plunging, too.

If you’ve ever considered a 15-year loan term, it’s a terrific time to talk to your lender. According to Freddie Mac’s weekly mortgage rate survey of roughly 125 U.S. lenders, at 3.30 percent, the 15-year fixed rate mortgage is at its lowest point in history.

The 3.30% rate doesn’t come for free, however. Based on average loan term nationwide, borrowers in San Francisco Bay Area choosing to “go 15″ should expect to pay 0.6 discount points at closing. 1 discount point is equal to 1 percent of your loan size.

With low rates, 15-year fixed rate mortgage can be enticing; a primary benefit is the huge reduction in the long-term interest costs of your loan. The downside, though, is that monthly mortgage payments can be relatively large.

At today’s mortgage rates, a 15-year fixed rate loan carries a principal + interest payment of $705.10 per $100,000 borrowed — a 46% increase over a comparable 30-year fixed rate loan. If you can manage the bigger payments, though, you’ll reap $47,000 in interest payments savings per $100,000 borrowed in paying off your loan in full.

$47,000 per $100,000 borrowed is a huge amount of savings and those saved monies can be used to fund items such as college, home improvement, and retirement, among others.

That said, the 15-year fixed rate mortgage is not for everyone.

Because it comes with higher monthly payments, the 15-year fixed rate mortgage may add financial stress to your household budget. And, once you have committed to a 15-year loan term and its payments, you’re can’t “go back”. Your lender won’t revert your loan to a 30-year schedule without a refinance, and a refinance could be costly.

For the first time in a year, homeowners with adjusting mortgages are facing rising mortgage rates. The interest rate by which many adjustable-rate mortgages adjust has climbed to its highest level since September 2010, and looks poised to reach higher.

This is because of the formula by which adjustable-rate mortgage adjust.

Each year, when due for a reset, an adjustable-rate mortgage’s rate changes to the sum of fixed number known as a “margin”, and a variable figure known as an “index”. For conforming mortgages, the margin is typically set to 2.250 percent; the index is often equal to the 12-month LIBOR.

LIBOR stands for the London Interbank Offered Rate. It’s a rate at which banks lend to each other overnight.

Expressed as a math formula, the adjusting ARM formula reads :

(New Mortgage Rate) = (2.250 percent) + (Current 1-Year LIBOR)

LIBOR has been rising lately, which explains why ARMs are adjusting higher as compared to earlier this year. There has been considerable stress on the financial sector and LIBOR reflects the uncertainty that bankers feel for the sector. 

LIBOR last spiked after the collapse of Lehman Brothers in 2008 amid global financial fears. Analysts expect LIBOR to rise into 2012 because of bubbling concerns in the Eurozone.

Despite LIBOR’s rise, though, most adjusting, conforming ARMs are still resetting near 3 percent. For this reason, homeowners with ARMs in San Francisco Bay Area may want to consider letting their respective loans adjust with the market.

This is because an adjusting mortgage rate near 3 percent may be better than what’s available with a “fresh loan” — even as 5-year ARMs rates make new all-time lows. Unlike a straight refinance to lower rates, an adjusting loan requires no closing costs, requires no appraisal, and requires no verifications.

So, if you have an adjustable-rate mortgage that’s set to reset this season, don’t rush to refinance it. Talk to your lender and uncover your options. Your best course of action may be to stay the course.

Low mortgage rates are terrific — if you can get them.

One week after posting its lowest mortgage rate in 50 years, Freddie Mac reports that the 30-year fixed rate mortgage rose by an average of 7 basis points nationwide this week to 4.22%. To get the rate, you’ll pay an average of 0.7 “points”.

This week’s rise in the 30-year fixed rate mortgage pulled rates off their all-time lows so either you locked last week’s rock-bottom rates, or you missed it.

Mortgage rates are rising.

As a refinancing homeowner or home buyer in San Jose , rising mortgage rates are something to watch. This is because, as mortgage rates rise, so do the long-term interest costs of giving a mortgage, increasing your homeownership costs.

For example, if you failed to lock a rate last week when rates were bottomed, and then decided to lock-in only after rates had climbed 0.25 percent, at the new, higher rate, over the life of your loan, you would have responsibility for an extra $5,300 in interest costs for every $100,000 you borrowed.

Rising mortgage rates can be expensive.

For home buyers, rising mortgage rates pose a second problem — they erode your purchasing power. A home that fits your budget at today’s rates may not fit your budget at next week’s rates. And because mortgage rates change quickly, you can sometimes feel ilke you’re racing the clock.

The hard part about mortgage rates, though, is that we can never know what they’ll do next. On some days they rise, on some days they fall, and on some days they stay the same. Instead of trying to “time the bottom”, therefore, a good strategy can be to lock the first, low rate that fits your budget. Then, if rates are lower in the future, you can look to refinance at that time.

Mortgage rates remain at historical lows. It’s a good time to lock a rate.

Last week, at its 5th scheduled meeting of the year, the Federal Open Market Committee voted to leave the Fed Funds Rate in its target range near zero percent.

The Fed Funds Rate has been near zero percent since December 2008 and, in its official statement, the FOMC pledged to leave the Fed Funds Rate untouched for at least another 2 years.

This doesn’t mean mortgage rates will be untouched for 2 years, though. 

Mortgage rates and the Fed Funds Rate are two different interest rates; completely disconnected. If mortgage rates and the Fed Funds Rate moved in tandem, the chart at right would be a straight line.

Instead, it’s jagged.

To make the point more strongly, let’s use real-life examples from the past decade.

• June 2004, 529 basis points separated the Fed Funds Rate and the 30-year fixed mortgage rate
• June 2006, 168 basis points separated the Fed Funds Rate and the 30-year fixed mortgage rate

Today, the separation between the two benchmark rates is 407 basis points.

1 basis point is equal to 0.01%.

Between now and mid-2013, when the Fed may begin changing the Fed Funds Rate, the spread between rates will change based on economic expectation — not Fed action (or non-action). If the economy is expected to improve, mortgage rates in San Jose will rise and the spread will widen.

Should mortgage rates cross 6 percent before the Fed starts raising rates, it will create the widest interest rate spread in history, surpassing the 615 basis point difference set in August 1982. 

At the time, the Fed Funds Rate was 10.12% and mortgage rates averaged 16.27%.

On the other hand, if the economy shows signs of a slowdown for late-2011 and beyond, mortgage rates are expected to drop.

Shopping for a mortgage can be tough — especially in a volatile environment like the current one. Mortgage rates move independent of the Fed Funds Rate. Make sure you’re watching the proper market indicators. It’s your best chance to lock the lowest rate possible.

Mortgage rates in Northern California plunged to new 2011 lows this week. 

According to Freddie Mac’s weekly Primary Mortgage Market Survey, the national, average 30-year fixed rate mortgage fell to 4.39% this week — the lowest 30-year fixed reading since November 18, 2010.

The 0.16 drop from last week is the largest one-week rate drop in more than 2 years, and, although the 30-year fixed remains above its all-time lows from November 2010, two other benchmark products made new records this week.

Both the 15-year fixed rate mortgage and the 5-year ARM are reporting lower than at any time in recorded history.

Freddie Mac puts those average rates at 3.54% and 3.18%, respectively.

Mortgage rates are dropping for several reasons, including :

• U.S. economic growth is slower-than-expected
• The U.S. government plans to curb its spending
• Global investors seek the safety of U.S.-backed bonds

The first two items are unfavorable for business and, as a result, stock markets have sold off all week. The Dow Jones Industrial Average posted an 8-day losing streak and Thursday it made its biggest one-day loss since 2008.

When equities lose, bonds tend to gain. This leads mortgage rates lower.

Mortgage rates also fell on “safe haven” buying; bond buys made because of their relative safety to risky assets. Mortgage bonds are considered “safe” so when economies and geopolitics are uncertain, mortgage rates improve.

Going forward, there are reasons for mortgage rates to fall again. The economy won’t rebound overnight and neither will investor confidence. However, markets can be fickle and rates have been known to reverse quickly.

With rates as low as they’ve been history, it’s an advantageous time to refinance your home loan, or purchase a new property.

The interest rate differential between fixed-rate and adjustable-rate mortgages continues to widen and has now reached historic levels.

There’s never been a better time to lock an ARM.

According to Freddie Mac’s weekly Primary Mortgage Market Survey, homeowners in Palo Alto who lock their mortgage rate today will save 129 basis points on rate, on average, by choosing a 5-year ARM as their mortgage product as compared to a 30-year fixed rate loan.

The average 30-year fixed rate is 4.51%. The average 5-year ARM rate is 3.22%.

It’s the biggest interest rate spread between fixed-rate and adjustable-rate mortgage rates in Freddie Mac’s recorded history; a gap which is the result, in part, of the 5-year ARM dropping to all-time lows this week.

Rates for the 5-year ARM are even lower than during last year’s historic Refi Boom.

Putting today’s “spread” in action against a hypothetical $250,000 loan size, a homeowner that chooses an ARM over a fixed-rate loan would save $184.30 monthly, and would have $500 fewer closing costs.

That’s a 5-year savings of $11,558 — nearly triple what you would have saved just 2 years ago.

The main reason why today’s adjustable-rate mortgages are priced so aggressively relative to comparable fixed-rate loans is that Wall Street expects the economy to drag for the next several quarters, after which it expects an acceleration. 

ARMs tend to reflect short-term expectations for the U.S. economy which is why short-term mortgage rates are dropping.  Fixed products, by contrast, take a longer view and expectations for an economic rebound are pulling fixed-rate mortgage rates up.

For now, mortgage applicants can exploit the difference — especially those who plan to move within the next 5 years — but adjustable-rate mortgages aren’t right for everyone. ARMs carry particular risks about which you should be aware before locking.

Before you choose an ARM, therefore, talk it through with your loan officer. 

On a wave of uncertainty about Greece and its debt; and weaker-than-expected economic data at home, conforming 30-year fixed rate mortgage rates have fallen to levels not seen since December 2, 2010.

Mortgage rates have dropped 8 weeks in a row. Not even last year’s Refi Boom produced an 8-week winning streak. This season’s streak is historic.

The 30-year fixed rate mortgage now averages 4.49% nationally, down 42 basis points, or 0.42%, since early-April. For every $100,000 borrowed, that equates to a monthly savings of $25.24.

Adjustable-rate mortgages have shed even more, giving back 50 basis points since the streak began.

Because of low rates, it’s an excellent time to buy or refinance a home relative to just a few weeks ago. Note, though, that depending on where you live, you may find your quoted interest rates to be slightly higher or lower than what Freddie Mac reports in its survey. This is because the Freddie Mac figure is a national average.

Mortgage rates and fees vary by region:

• Northeast : 4.49 with 0.6 points
• Southeast : 4.52 with 0.8 points
• North Central : 4.52 with 0.6 points
• Southeast : 4.52 with 0.6 points
• West : 4.45 with 0.8 points

You’ll notice that, in the West Region, rates tend to be low and fees tend to be high; in the North Central Region, the opposite is true. You should expect California to have its own pricing norm within this region, too.

Is there a particular rate-and-fee setup that suits you best? The good news is that you can ask for it — no matter where you live.

If having the absolute lowest mortgage rate is more important to you than having the absolute lowest fees, ask your loan officer to structure your loan in the “West” style. Or, if low costs are more your style, ask for them.

Mortgage rates appears as if they’re headed lower but don’t forget how quickly markets can change. Once they do, mortgage rates in San Jose should spike. Exploit today’s market while you still can.

A mortgage comes with many moving pieces and understanding them is the key getting a great deal. Unfortunately, studies show that few Americans have a firm grasp of how mortgages work — from mortgage types to mortgage fees.

In this back-to-basics interview on NBC’s The Today Show, you’ll learn some mortgage planning basics to help you get smarter with your next home loan in San Jose or anywhere else — purchase or refinance.

Some of the topics covered include:

• The mortgage applicants for whom adjustable-rate mortgages are a better choice than fixed-rate mortgages
• Why you should include “How Good Is This Lender?”-type questions in the rate shopping process
• What a pre-approval letter is good for, and what it is not good for

There is also one of the most simple explanations of “discount points” ever offered on network television.

The video runs 4-and-a-half minutes. For first-time buyers and experienced ones, it’s worth a watch. You’ll pick up some tips to use on your next mortgage.

Mortgage rates across the state are near year-to-date lows, but locking them in this week may be difficult. As Memorial Day nears, and Wall Streeters get a head-start on the long weekends, trade volume in the mortgage bond markets will dip.

When bond volume drops, mortgage rates get jumpy. It’s a relationship based more on scarcity than actual market fundamentals.

It works like this:

1. Conforming and FHA mortgage rates are based on the “market price” of a mortgage-backed bond
2. Mortgage-backed bonds can’t be bought or sold without a buyer and a seller at a specific price

As Friday gets closer this week, and more and more Wall Street traders will leave for their “extended” 3-day weekend, and bond markets will be left with fewer and fewer participants. This will create a market situation in which it’s harder to match a buyer and seller at any given bond price, resulting in larger mortgage rate shifts than usual.

These jumps in rates are exaggerated during periods of economic uncertainty like these. What’s more, there’s a lot of economically-important data due for release this week. That, too, can put markets in hysterics.

If this were a “normal” week, mortgage rates would be volatile. The coming of Memorial Day is just adding to the mix.

Mortgage rates may rise in Mountain View this week, or they may fall.  Either way, if you have the opportunity to lock something favorable, consider doing it.  Rates are low and likely won’t last.

Among the most challenging aspects of shopping for a mortgage is how rates change constantly. It’s hard to pin them down.

For example, in 2011, mortgage rates have expired every 3-and-a-half hours, on average. That’s fast.

There’s two main catalysts for changing mortgage rates.

The first can be grouped as ”scheduled events”; the planned release of market data which includes the Existing Home Sales report, or a scheduled government statement such as when the Federal Open Market Committee meets. When the outcomes of these event-types either exceed, or fall short, of Wall Street’s expectations, mortgage markets react.

Home buyers and rate shoppers in Mountain View realize this as higher (or lower) mortgage rates.

Then there’s the other type of catalyst — the “unscheduled event”.

Unscheduled events take many forms and are often called “surprise developments”. The Federal Reserve’s plan to inject $750 billion into mortgage markets in 2009 was one such surprise. Most geopolitical events fall into this category, too.

Unscheduled events are often unsettling to Wall Street because investors don’t have specific contingency plans for them like they would if, say, this month’s jobs report comes back exceedingly strong. For example, investors didn’t expect North Korea to fire missiles over Japan in 2008, nor did they expect a volcano to erupt in Iceland last spring.

When unscheduled, unexpected events occur, the market’s first — and natural — reaction is to scramble to make sense of it. Mortgage rates get jostled as a result and can take days to settle back to normal.

We’re experiencing an “unexpected event” right now.

In response to Sunday’s evening’s presidential address, markets are now upended. The dollar is strengthening, oil prices are falling, and stock markets are rising. Each of these items are altering mortgage rates across Northern California.

Even today, markets remain unsettled.

Therefore, if you’re shopping for a mortgage rate, keep one eye on the news and the other on the rate-lock trigger. During periods of unexpected activity, mortgage rates can change quickly so be ready to shop, and be ready to lock.

Mortgage markets wait for no one.
