Whether paying a higher interest rate is better or worse than paying
mortgage insurance depends on a variety of factors, including how long
the borrower expects to have the mortgage and how rapidly the property
appreciates. All the factors can be pulled together in calculator 14a.
Mortgage Insurance Versus Higher Interest Rate
"We have a 5 percent down payment and our lender has offered us a Tax
Advantage Mortgage Insurance plan instead of conventional private
mortgage insurance (PMI). Instead of paying a mortgage insurance
premium, we pay a higher interest rate. The lender says we come out
ahead because the higher interest payments are tax deductible. The rate
on the Tax Advantage loan is 8.375 percent compared to 7.5 percent on
the conventional loan. We are in the 28 percent tax bracket. Is this a
deal for us?"
Virtually all lenders in the US require PMI on mortgages with down
payments less than 20 percent, but some will accept a higher interest
rate in lieu of PMI. When a borrower accepts this option, the lender
buys PMI for less than the borrower would have to pay. The higher
interest rate covers the insurance cost to the lender, perhaps including
a profit margin.
The sales pitch for the higher rate as a replacement for PMI is that
interest is tax deductible whereas PMI premiums are not. The other side
of the coin, however, is that you must pay the higher interest for the
life of your mortgage, while mortgage insurance will be terminated at
some point.
In 1999, Congress mandated that on most loans closed after July 29,
1999, mortgage insurance must be cancelled at the borrower's request if
the loan balance is paid down to 80 percent of the original property
value. Further, insurance must be terminated automatically when the
balance reaches 78% of original value. In addition, subject to certain
conditions, PMI on loans sold by lenders to the two Federal agencies
(Fannie Mae and Freddie Mac) must be cancelled when the loan balance
reaches 75% of the current property value, after 2 years, and 80% after
5 years. See

Using Calculator 14a to Get an Answer
There is no way you can figure in your head whether the higher rate or
PMI results in a lower cost. However, calculator 14a,
Pay For Mortgage Insurance or Pay a Higher Interest Rate will do it for you. To crunch
the numbers you'll have to give the calculator relevant facts about you
and your mortgage, including:
Tax Bracket: Because of interest deductibility, the higher your tax
bracket, the greater the benefit of the higher rate relative to PMI.
Life of Mortgage: Because tax savings are highest in the early years,
while mortgage insurance premiums decline or disappear entirely at some
point, the relative advantage of the higher rate is greatest if you
expect to be in your house only a short time.
PMI Premium: The higher the PMI premium, the more likely the higher rate
is a better deal. Premiums vary with the type of loan, term, down
payment and other factors.
The Rate Increment: The smaller the increase in the interest rate
charged in lieu of PMI, the greater the advantage of the higher rate
loan.
Property Value Appreciation: Appreciation can lead to early PMI
cancellation, as noted above. For example, assuming 5% down on a 7.5%
30-year loan and property appreciation of 1% a year, the loan balance
reaches 80% of value in 93 months; with 2% appreciation, the target is
reached in 67 months; and at 3%, in 52 months. The
Pay For Mortgage Insurance or Pay a Higher Interest Rate calculator
allows you to explore how these possibilities of early termination
affect the relative cost of the high-interest rate option.
In your case, I first assumed that termination of PMI does not occur
until the loan balance reaches 78% of original property value. In that
event, the higher interest rate loan would be the better deal if you
hold the mortgage less than 24 years. Then I assumed that termination
occurred when the balance reached 80% of appreciated value, and that
your house appreciated by 1% per year. This was sufficient to reduce the
cross over point to 13 years. With 2 percent appreciation, it falls to 8
years, and at 3% to 6 years.
Bottom line: If you expect significant appreciation and monitor your
property value so you can terminate PMI as soon as possible, the higher
interest rate option is a poor choice -- unless you expect to hold the
mortgage a very short time.
The Public Policy Issue
The higher interest rate option usually means that the lender is
purchasing the mortgage insurance and passing the cost along in the
rate. This may or may not offer a better deal to the borrower, but in
the long run, a system in which lenders buy the insurance is better for
borrowers than one in which borrowers pay for the insurance. Lenders
purchasing insurance have an incentive to drive down the premium,
whereas there is no such incentive when borrowers pay the premium. For
