Missouri state law speaks to when the initial appraisal is required for ORE and then defers to GAAP.
http://www.sos.mo.gov/adrules/csr/current/20csr/20c1140-2.pdfSpecifically, for an initial appraisal, it says:
(3) At the time real property is transferred to
the other real estate category, if the recorded
value of the real estate exceeds two hundred
fifty thousand dollars ($250,000), the bank
shall obtain a current appraisal prepared by
an independent qualified appraiser to substantiate
the fair market value of the real
property; provided that if such property has a
recorded value of two hundred fifty thousand
dollars ($250,000) or less, an evaluation shall
be performed and placed in file. For purposes
of this section, the evaluation must: a) be
in writing; b) be dated; c) describe the real
estate, its condition, and both current and
projected use; d) list the sources of information;
e) describe analysis and supporting
information; f) give an estimate of market
value based, as appropriate, on cost and
income, and any limiting conditions; and g)
provide the name, address, and signature of
preparer, who must have real estate training
or experience, knowledge of the market and
have been independent of the loan decision.
For the purpose of this section, the bank will
be considered to be in compliance if—a) the
bank has obtained an appraisal or evaluation,
as appropriate, within six (6) months prior to
acquisition or b) within thirty (30) days after
foreclosure, the bank has documented an
agreement with an individual or company to
perform the appraisal or evaluation, as appropriate;
however, the appraisal or evaluation,
as appropriate, shall be completed and in the
bank’s files within ninety (90) days of foreclosure.
