How Appraisals and Assessments Differ
Many people think appraisals and assessments are the same thing
or at least that they should be for the same amount. The truth
is they can vary greatly. Let's look at each of them.
Appraisals
An appraisal is an estimate of market value. An appraiser can
use many methods for coming up with this estimate. For income
producing property, the appraiser may capitalize the value of
the income stream. (It would take "x" dollars of capital
invested at a "y" rate of return to produce an income equal to
the rental income generated by this property.) For other
properties, an appraiser may use "replacement value." (It would
cost "x" dollars to build this structure if it were being built
today.)
Appraisers usually use "comparable sales" when evaluating the
market value of a home. They look at nearby properties with
similar characteristics, which have sold in the recent past to
see at what price they sold. They typically give the most weight
to the property they deem to be most like the property they are
appraising.
Buyers and sellers generally encounter appraisals when the
buyer's lender has an appraiser make an evaluation of the market
value of the property being sold. The lender wants to be sure of
the value of the collateral for the loan. An interesting feature
that comes into play in this situation is that one indication of
value is at what price two unrelated parties will agree to buy
and sell the same property. In other words, what is the contract
price the seller and buyer of this property agreed on (if they
are not relatives).
Assessments
An assessment is the value your local government puts on your
property for the purpose of taxing it. How this value is derived
varies from jurisdiction to jurisdiction. Some communities say
the value is the same as market value. Some say the value is a
percentage of market value. Some appear to actually do what they
say they do, and some do not.
I was once a partner in an investment property that we were
offering for sale at the time the county re-assessed it. Imagine
my annoyance when the assessment came in at one hundred and
forty percent of the offer price. We weren't dummies. The
partners were real estate professionals. I appealed the
re-assessment, but my appeal was turned down. I offered to sell
the property at the assessed price to the appraiser the county
had hired to handle the appeals when he was telling me why he
could not reduce our assessment. He did not take me up on my
offer. Our property sold at the listed price months later. We
had paid six months' taxes on the property at a higher than
market value.
On another occasion I helped some elderly people sell a farm
they'd lived in all their adult lives. The farm sold for a price
a great deal higher than the value at which it had been assessed.
I believe the two examples are fairly typical. Many
jurisdictions will "puff up" assessments for businesses and
investors and "low ball" assessments for people who have lived
in their homes for a long time. Sometimes there are formulas for
doing this. "Land use" is one such concept, i.e., the property
is taxed at its value as a farm and the fact that it is ripe for
dense residential and commercial development is ignored or
deferred. Sometimes there are no formulas. It is just done.
For these reasons, it is usually not a good idea to put too much
credence in the assessed value of a property when you are trying
to figure out market value. They may be the same. They may be
vastly different.
