The Automated Valuation Model is something that every
mortgage agent and broker would be well served to understand and make a part of
their workflow.
Lenders, from private lenders all the way to
institutional lenders, have been using the Automated Valuation Model for years
and you may remember CAAMP touching on them when completing your mortgage agent
or brokers studies.
The Automated Valuation Model is an automated program
that can produce an estimate of a property’s value. The value is statistically
derived using mathematical modeling and in the case of Teranet comes from
public record data found in the POLARIS database. The AVM compares the subject
property to that of comparable sales data of similar properties to produce the
value estimate.
There are many different types of AVMs that gather
information from different sources and formulate estimates using different
formulas.
These include:
·
The House Price Index Model which uses data from
house price indices
·
The Tax Assessed Value Model which uses tax
assessment data
·
The Hedonic Model which uses similar property
sales to generate its value estimate
Because AVMs involve a value estimate, some make the assumption
that the purpose of an AVM is to replace the need for an appraisal and its
accuracy.
AVMs are extremely accurate because the numbers don’t lie
and their values are generated based on data with no human element. With that
said, they are not an appraisal and are often used at different stages in the
underwriting and funding processes.
Many lenders, mortgage agents and brokers alike will use
AVMs at the application stage to validate the value stated on the application
and determine if it is worth proceeding with the approval and funding process.
Many times an AVM will come before an appraisal is ordered. In instances where
equity permits, sometimes there is enough equity for the AVM to be relied upon
on its own. Based on the accuracy of
AVMs, there is also wide spread usage amongst mortgage insurance providers to
evaluate their ability to insure new deals
Appraisals have a human element which means that the
appraiser will use their chosen comparables, and render their professional
opinion on interior and exterior conditioning. Appraisers can also uncover
properties under construction and even properties that have undisclosed
tenants.
Since comparables are chosen by the appraiser, it makes
good sense to review an appraisal against an AVM because an AVM will consider
all comparable sales – not 2 or 3 as is the case with an appraisal.
AVMs have not historically been available to brokers but
in recent years this has changed. Mortgage agents and brokers can now obtain
and review an AVM before they even submit a deal to a lender.
Using both and AVM and an appraisal at different stages
in the process can be quite valuable, and save you time and money on broken
deals. Purview For Mortgage Brokers’ AVM provides accurate data you can rely
on. Contact us today at 1.855.787.8439.
