A companion article reported the results of a mortgage shopping
expedition in December 2008, but did not say much about how I got those
results. See
Mortgage Shopping In a Stressed Market. This article is about
shopping technique. In a highly imperfect market, an investment in the
time needed to shop effectively can pay large dividends.
Shop On-Line
Prices shown in printed media are obsolete when they are published.
Price quotes offered over the telephone are worthless. But lenders
generally are prepared to deliver the prices they post online.
Shop On Friday
Because the market is highly volatile, valid price comparisons have to
be made on the same day. You don’t shop lender A on Monday and lender B
on Tuesday because prices are reset every morning.
My favorite day to shop is Friday because the prices lenders post on
Friday hold until Monday, which gives me more time if I need it. If you
shop any other weekday, you have to finish it all before prices are
reset the following day.
Decide the Instrument You Want
I have tutorials to help you make these decisions, see
Tutorials in Selecting Mortgage Features, which
are affected not only by your personal preferences, but also by the
market prices of the different instruments. Last week, for example, I
advised against conforming adjustable rate mortgages (ARMs) because all
the lenders priced them higher than fixed-rate mortgages (FRMs). Once
you know the type of instrument you want, you are ready to compare the
prices of different lenders for that instrument.
Compare Costs at the Same Interest Rate
Lenders usually post interest rates in even multiples of .125%, which
makes it easy to find a common rate offered by different lenders. The
question then is, which lender has the lowest cost for that rate? This
is a little tricky because of the different kinds of data that lenders
provide.
Comparing Costs on FRMs
If 2 lenders offer, say, 5.5% on a 30-year FRM,
the better deal is the one with the lower total lender fees. Lender fees
consist of charges expressed as a percent of the loan, usually called
“points”, plus charges expressed in dollars. Dollar charges are usually
broken down by category, but the total is the only number relevant to
the borrower.
Some lenders will show total lender fees, which makes it easy, but
others only show points. They must always show the annual percentage
rate (APR), however and this is an adequate substitute because it is
calculated using all lender fees. If you compare two FRMs at the same
rate, the one with the lower APR has the lower total lender fees. Note:
APRs of FRMs with different interest rates are not comparable.
Comparing Costs on ARMs
Borrowers who are 95% certain they will pay off
their mortgage before the end of the initial rate period can use the
same method to determine the best deal on an ARM as on an FRM: select a
common interest rate and compare total lender costs at that rate. You
can compare different ARMs, or an ARM with an FRM. Note: On an ARM, you
cannot use the APR as a proxy for total cost, you must get cost data
from the lender.
If there is a significant probability that you will still have the
mortgage at the end of the initial rate period, I suggest you use
calculator 9a,
Interest Cost Calculator: Fixed-Rate Mortgage Versus ARM
With No Negative Amortization, to calculate interest cost over both the
initial rate period and that period plus 5 years. Interest cost is a
comprehensive measure of cost similar to the APR except that it can be
calculated over any time period – the APR assumes all loans run to term.
To calculate interest cost over the longer period, you must know the
features of the ARM that affect the future rate. These are the margin,
index and rate caps. Upfront Mortgage Lenders (UMLs) disclose this
information on-line, but most other lenders don’t. You have to get it by
asking. Make sure the answer is in writing.
The calculator must be told what happens to the ARM rate index after the
initial rate period ends. I recommend two polar assumptions: “Stable
Index” and “Worst Case”. Then for each ARM, you have one cost figure for
the shorter period, and two for the longer period that bracket the
possible outcomes.
Third Party Services
The procedures described above do not take account
of the cost of third party services, including title insurance and
appraisal. Borrowers are typically steered to service providers, many of
whom will over-charge them. This is a weak point of the system that I
have written about on many occasions. However, the largest third party
charge is title insurance, and in some cases, borrowers can now save
money by purchasing their own title insurance on-line from
