Current Cambridge Fifteen Year Mortgage Rates

Here is a table listing current Cambridge 15-year fixed rates.

What Loans Do Home Buyers Choose?

Across the United States 88% of home buyers finance their purchases with a mortgage. Of those people who finance a purchase, nearly 90% of them opt for a 30-year fixed rate loan. The 15-year fixed-rate mortgage is the second most popular home loan choice among Americans, with 6% of borrowers choosing a 15-year loan term.

Loan Type Percent of Borrowers Buying a Home Percent of All Home Buyers
30-year Fixed 90% 79.2%
15-year Fixed 6% 5.28%
Adjustable-rate 2% 1.76%
Other Fixed-Rate Loan Terms 2% 1.76%
Use Any Type of Financing 100% 88%

When interest rates are low (as they were after the global recession was followed by many rounds of quantitative easing) home buyers have a strong preference for fixed-rate mortgages. When interest rates rise consumers tend to shift more toward using adjustable-rate mortgages to purchase homes.

Most consumers obtaining mortgages to purchase a home opt for the 30-year fixed-rate mortgage. It completely dominates the purchase market.

Purchase Loans Only.

If one looks exclusively at purchases FRMs are about 90% of the market. 30-year loans are also a popular choice for refinancing homeowners, though the 15-year option is also popular with people refinancing their loans. The following chart shows the blended overall market condition, but if you can compare it against the above chart you can visualize how 15-year loans are much more popular for refinancing than for initial home purchases.

Advantages of a 30-Year Mortgage

The big advantage of a 30-year home loan over a 15-year loan is a lower monthly payment. This lower payment in turn makes it easier for home buyers to qualify for a larger loan amount.

If the homeowner has other investments which offer superior returns to real estate then they can invest the monthly difference into those higher yielding investments.

Homeowners can also deduct mortgage interest expense from their income taxes on the first $750,000 of mortgage debt. Slowly paying down mortgage debt while accumulating assets in a tax-advantaged retirement account can help people compound wealth quicker.

Provided one has a stable job & a stable source of income, financing their home using a 30-year loan offers great flexibility. If interest rates rise, the monthly loan payments do not change. If interest rates fall, the home buyer can refinance into a lower rate and/or a shorter duration loan. And if an owner comes into some money through a work bonus, an inheritance or another winfall they can apply any extra cash to pay down their loan quicker.

Disadvantages of a 30-year Mortgage

Of course the pro for one type of loan is the con for another. The above advantages can also be viewed as disadvantages in certain circumstances. For example, if the cap on mortgage interest deductability is lowered then that benefit is reduced. And if the stock market declines sharply after one invests aggressively near peak valuations then they probably would have been better off using that money to pay down their mortgage quicker.

The flexibility of a 30-year payment plan can be both a blessing and a curse. For those who are disciplined making extra payments while retaining the longer duration loan can be a good move. But many people find ways to spend whatever "extra" cash they have laying around & for these people a shorter duration loan that builds equity faster can be a great decision.

Advantages of a 15-Year or 20-Year Home Loan

 

Buyers who can afford the slightly higher monthly payment associated with a shorter duration mortgage have a number of advantages.

  • Lower interest rates: While both loan types have similar interest rate profiles, the 15-year loan typically offers a lower rate to the 30-year loan. The spreads change over time, but the 15-year is typically about a half a percent lower than the 30-year. The 20-year is typically priced between the 2 other options, slightly closer to the 15-year.
  • Build home equity much faster: Historically American homeowners typically move homes or refinance about every 5 to 7 years. After the Great Recession this window moved out to about 10 years. If a person stretches their loan payments out to 30-years they build limited equity in their home in the early portion of their loan. A person who pays off a home in half the time is not making a payment which is twice as large. There are other costs of ownership including property taxes, insurance, maintenance & in some cases HOA fees. These other expenses can make up to 1/3 of the typical monthly expense on a 30-year mortgage, so paying off a specified amount of debt in 15 years rather than 30 years may only represent a 30% to 35% larger total monthly payment.
  • Greater life certainty: The recovery since the 2008 financial crisis has been uneven, with increasing income inequality & a greater sense of economic uncertainty than just about any economic recovery since the great recession which followed the 1929 stock market crash. The rise of globalism, monopoly technology platforms, distributed software with zero marginal cost & artificial intelligence are likely to create massive & ongoing waves of structural unemployment. Few people know what the world will be like in 20 years, so perhaps it doesn't make sense to finance the largest purchase of their lives across 30 years. Those who build equity faster will have greater certainty in their lives & won't be anywhere near as worried about what happens if they lose their job 23.5 years from today.

20% Down Payment

Home buyers who have a strong down payment are typically offered lower interest rates. Homeowners who put less than 20% down on a conventional loan also have to pay for property mortgage insurance (PMI) until the loan balance falls below 80% of the home's value. This insurance is rolled into the cost of the monthly home loan payments & helps insure the lender will be paid in the event of a borrower default. Typically about 35% of home buyers who use financing put at least 20% down.
