PORTLAND, MAINE PROPERTY REVALUATION
Frequently Asked Questions
WHO IS CONDUCTING THE REVALUATION? Portland has engaged Tyler Technologies to conduct the 2025
revaluation project. Tyler has more than 85 years of experience and is North America’s premier national appraisal
services company. Tyler has completed reassessment programs in nearly every state and has appraised more
than 33 million parcels since 1938.
WHY IS THE CITY REASSESSING? The last revaluation of Portland was completed in 2021. The revaluation prior to
2021 occurred in 2006, a 15-year time span. The City has decided to conduct more frequent revaluations to
minimize the amount of potential tax shifts between different types of properties and different areas of the City.
Property values have changed since 2021 and as a result, inequities in taxation may be occurring. Some property
owners may be paying more than their share of property tax and others may be paying less. The reassessment is
being conducted to address these inequities and ensure that each property owner pays only their fair share of the
tax burden; no more, no less.
HOW WILL THE CURRENT REVALUATION BE CONDUCTED? This current revaluation has an effective valuation
date of April 1, 2025. Tyler employees and Assessor’s Office staff will be analyzing sales of City properties that have
taken place in the two years prior to this date. Based on this new sales information, neighborhood and overall valuation
adjustments will be made. Additionally, for commercial properties, current rental and expense information will be
analyzed and considered. Properties that have outstanding building permits will be visited, inspected, and their property
data updated by the City Assessor’s Office.
WILL I RECEIVE DETAILS ABOUT MY PROPERTY? As part of this revaluation, property owners will receive a parcel
inventory mailer listing the characteristics on file for their property. This is an opportunity for owners to make any
needed corrections to the data.
WHAT ABOUT PHOTOGRAPHY? As needed, new photos will be taken from the public right of way of properties
that have recent physical changes. These images will become part of the City’s computer assessment database.
WILL COMMERCIAL, INDUSTRIAL AND EXEMPT PROPERTY VALUATIONS BE UPDATED?
Yes.
Naturally, factors
will differ from those affecting residential properties. Information, such as building income, expenses, and vacancy
rates will be gathered in addition to physical characteristics.
WHAT IS THE NEXT STEP? Tyler will perform valuation analysis using computer‐assisted mass appraisal (CAMA)
techniques. During this process, Tyler appraisers will analyze local building costs, property sales, commercial
income and expense information, and other valuation factors to establish preliminary market values. These initial
values are then reviewed to check for accuracy and consistency. Appraisers then make any necessary changes.
HOW IS MY PROPERTY’S VALUE DETERMINED? The market value of your property is determined by using the
property data. Data mailers will be sent to ask you to verify that the existing data is correct. Tyler analyzes recent
sales of similar properties in your area of the City and considers construction costs and income and expense
information, where appropriate.
WHEN WILL PROPERTY OWNERS BE NOTIFIED OF NEW VALUES? This information will be mailed to all owners
beginning in April 2025. These values will first be used to calculate new tax bills starting with the Fiscal 2026 tax
year.

WHAT IS MARKET VALUE? There are several long explanations of market value, but simply put, it is the most
probable price a willing buyer would pay a willing seller for a property on the open market if neither party were
under pressure to buy or sell.
HOW CAN I TELL IF MY NEW VALUE IS CORRECT? You should ask yourself, could I or would I sell my property for
the amount listed as my new assessment. You can check this against sales of similar properties in your
neighborhood. To help you compare, listings of preliminary values and other data for all properties in the City will
be available for comparison on the internet on the City’s website. Properties currently for sale can be found on
the internet at various real estate sites.
SHOULD THE PRELIMINARY ASSESSED VALUE BE THE SAME AS THE PURCHASE PRICE FOR MY PROPERTY? If
you purchased your house within the past year on the open market with no unusual conditions, and have not
changed the property, the appraised value on your notice should be reasonably close to the sale price, but
probably will not be the exact amount. Just because one person is willing to pay a certain amount for a property
doesn’t mean that the majority of buyers would be willing to pay the same price. While sale prices may vary
slightly, even for identical properties, the assessor must be equitable in assigning valuations. Therefore, similar
properties will have similar appraised values, even if they might sell for a little more or less than the appraised
value. Along the same lines, even if you appealed your value (assessment) in a prior year to the Portland Board of
Assessment Review, and the value was adjusted, the revaluation appraises each property as if it had not been
valued before. Any prior changes are not considered since those changes were based on the old, outdated
system. The new value you receive should be a reasonable estimate of market value and equitable with
surrounding properties of a similar type.
ARE EXEMPTIONS INCLUDED IN THIS PRELIMINARY VALUE? Any existing exemptions are not included in your
preliminary valuation but will be in the taxable value you receive from the City after the reassessment in 2026
(taxable value equals the assessed value less any exemptions that may be applicable). Questions concerning
exemptions must be directed to the Portland Assessor’s Office.
HOW WILL REASSESSMENT AFFECT MY TAXES? By itself, a reassessment is revenue neutral, although it will cause
tax burden shifts among properties. An increase in the total taxable valuation of the City will result in a decrease
of the millage or tax rate. Because of this, an increase seen in the assessed value of your property does not always
mean that taxes will increase for the property. The determining factor is how much your property increases in
value in relation to the City’s total valuation increase. Some owners will see increases while others will see
decreases, and yet others will remain approximately the same.
WHAT IF I AM NOT SATISFIED WITH THE NEW VALUE? Informal value review meetings will be conducted by Tyler
from April 2025 through May of 2025. If a property owner is not satisfied with the results of the informal review, a
formal appeal may be filed with the City of Portland Assessor’s Office.
WHEN WILL I LEARN THE RESULTS OF THE INFORMAL REVIEW? No value changes will be made at the time of the
informal review, but all information you supply will be reviewed. The taxpayer will be notified of the results of the
informal review by way of a first-class letter.
WHAT IF I AM STILL NOT SATISFIED WITH MY ASSESSMENT? If you disagree with the results of the informal
review, your next step would be to file a formal appeal with the City of Portland Assessor’s Office. The deadline
for filing an appeal is 185 days from the date of Tax Commitment for the tax year for which you are filing an
appeal.
