The multiple listings service
(MLS), for a long time, has been what many real estate professionals and
lenders alike have used to pull sales comps when trying to establish the list
value of a property. Comparably, many appraisers have also relied up upon tools
like the multiple listings service and GeoWarehouse to pull sales comparables.
But do mere sales comparables
go far enough in today’s lending environment?
In the past 10-15 years, this
practice has changed significantly. The internet and technological advances
have brought us other tools such as Automated Valuation Models (AVM), and have
provided a more comprehensive way to crunch data in order to generate property
value.
Automated Valuation Models
generate a value based on all comparable sales in an area entirely, not just 2
or 3 that appeal - what often occurs when a human is browsing their local
MLS.
The multiple listings service
is a database that stores information around sales and listings, while AVMs
have their own respective data sources and methods for analyzing the data. The
3 most common types of AVMs draw their data from distinctive sources or using
different approaches.
1. The House Price Index Model – This model looks at multiple
repeat sales which then result in house price indices in different geographical
locations. This is then applied to the past transaction price to generate a
current valuation.
2. The Tax Assessed Value Model – This uses data from
municipalities that store property value information in connection with tax
assessments. In this model past values and subsequent values are used to create
a ratio which is often relied upon when updated the tax assessed values of
properties.
3. The Hedonic Model – This model uses price information about
all sales related to comparable/similar properties in an area using
property specific attributes. The value is then generated using a radius search
pattern and other logical search parameters.
Some tools only produce AVMs,
while other tools produce AVMs within a report containing other property data.
· The old fashioned way
of investing in real estate: See a property, ask to see multiple listings
comps, if deciding to move forward – order an appraisal.
· The new way of
investing in real estate: See a property, generate an AVM on your tablet or at
the office, if moving forward you may or may not request an appraisal to
accompany your AVM depending on equity.
Appraisals are not AVMs and
AVMs are not appraisals. AVMs don’t take into consideration the condition of a
property or things that real-time boots on the ground can. Lenders who want to
dig deeper use their AVM as a first search measure and then couple it with an
appraisal to get a more complete and accurate picture.
Sound complicated? Not so much.
In fact, the big banks have been using AVMs for the past 10-15 years.
Technology has made them so much more accessible that many smaller lenders,
such as credit unions, finance companies and even individual private lenders,
have integrated the use of AVMs into their workflows.
