For more information on the revaluation in general, or on the residential revaluation results, please visit the other web pages on this topic:
Overall, the 2019 revaluation shows that the City of Bath's residential property values have increased by about 14%. Individual properties may have changed more or less than the average; some property valuations even went down compared to last year.
All of the City's residential properties and their proposed valuations can be reviewed in the PDFs published below. We have several versions of the information, sorted by address, by map and lot, by property owner, and by property type. These can be used to compare the valuation of your property with others similar properties.
Some reports also contain the old values as well as the new ones, though the amount a particular property's value has changed compared to the amount of change for other properties should not affect the judgement about whether or not the new value is a valid or accurate determination of the market valuation for the property.
Finally, a list of old and new values for residential properties is also available for download in Excel.

The 2019 Revaluation for the City of Bath relied upon studying city-wide property sales between April 1, 2017 and April 1, 2019 to establish the values of all properties city-wide, after accounting for differences in property type, location, lot size, etc. The qualified sales we reviewed for the revaluation are posted below in Excel and PDF formats. "Qualified" generally means sales that are arm's length transactions on the open market. Foreclosure sales and sales where the property was significantly improved after the sale but before April 1, 2019 are examples of sales that were not qualified.
Some of the following sales reports include only one year of sales; others contain two years. If you want to look at both years of sales (2017-2019) for any of the categories, you should be able to use the report of all the qualified sales from 2017 to 2019, downloadable in excel, to obtain the information.

Some of the reports have codes that may not be familiar. Here's a glossary of some of the common abbreviations in the sales reports.
|Word or Code||Definition|
|ASR or A/S Ratio||Assessment to Sale Ratio, or the assessed value divided by the sales price.|
|AYB||Actual Year Built (if known). Often, the year 1900 in this field is assessor-speak for "We don't know, but it's old." Many Bath buildings were built in 1900.|
|COD||Coefficient of Dispersion. A statistical term that measures how far apart a set of numbers ranges (above and below) the median, or center, of the set of numbers. In these reports, the COD measures how close all the assessment to sale ratios (ASR) in that particular set are to the median ASR of that set. A lower COD means a higher quality of assessment, usually. When there are very few sales, however, this becomes not terribly meaningful. In a neighborhood with lots of very similar properties, the COD will be lower than it is in a neighborhood with many different types of properties. A COD of over 20 is an unacceptable level of assessment variation, according to Maine Revenue Services.|
|Eff Area||Effective Living Area, a calculated amount of square feet used in assessing that reflects the contributions of non-living area parts of the property (for example, decks, or cathedral ceilings, or basements) to the value of the property.|
|GLA||Gross Living Area, or the total of building's living area (generally, finished, interior, conditioned space). Some parts of a building are not living areas (like a deck, or a basement), and other areas, like a finished attic, may have less living area than they do floor space, because of the kneewalls.|
|MBLU||Map Block Lot Unit. In Bath, this is actually the Map, Lot and Sublot, a description of the location of every parcel on the City's tax maps.|
|Mean||Mean is another word for average. If there were 5 numbers arranged from smallest to largest (for example, 1, 1, 3, 4, 5), the mean would be (1+1+3+4+5)/5, or 2.8.|
|Median||The Median is the literal middle of a set of numbers, when arranged from small to large. If there were 5 numbers arranged from smallest to largest (for example 1, 1, 3, 4, 5), the median would be 3, because there are 2 numbers smaller on the list and 2 numbers larger than it on the list..|
|PID||Parcel ID. This number is used only to identify parcels within the Vision assessing software.|
|PRD||Price-related Differential. This is another statistical measure of whether assessments may be biased by in valuing high-value properties at a higher or lower assessement to sale ratio than low-value properties. Because of the way it is calculated, the PRD isn't terribly accurate. But a PRD above 1.03 tends to show assessment regressivity; a PRD below 0.98 tends to show assessment progressivity.|
