This map plots a dot for a house sold in Old Lyme between 2020 and 2025. The color represents the year the property was sold. I've excluded $0 and $1 sales, and I only looked at the most recent sale. So if a house sold in 2021 for $300,000 and then the property was transferred to a trust for $0 in 2022, it would be excluded from this map.
This map breaks the lot sizes up into 10 buckets and gives each a color. The buckets are:
0ac, 0.1ac, 0.25ac, 0.5ac, 0.75ac, 1.0ac, 2.0ac, 4.0ac, 5.0ac, >5.0ac
This map plots the increase in the total appraisal value (land + improvements) from 2023 to 2024.
the data is grouped into buckets like: decrease - 0%, 1-10%, 11-20% ... 90-100%, >100%.
This is a plot of the various "neighborhoods" in Old Lyme. Each property record has a Neighborhood code
associated with it. Each code has a different color on the map. This becomes interesting when you
compare it with the "Land Value Increase Map" below. There appears to be a correlation between
the neighborhood and the increase in land value.
This map shows the percentage increase (or decrease) in the land value of a property from 2023 to 2024.
This data is not bucketed, but rather it's the colors are normalized from -100% (red) - 100% (green).
This map plots the price per acre of land. The data is bucketed into groups of $100,000 per acre,
and then a catch-all for land above $1,000,000 per acre. Properties close to the water clearly
stand out.
The improvements value map shows the percentage increase (or decrease) in the improvements (the house)
on a property between 2023 and 2024. This data is bucketed into groups of 10% with a decrease-0% bucket
and a >100% bucket on either end.
This map shows the appraisal value of the properties. The data is normalized between
yellow (the lowest priced property) and dark red (the highest priced property). This map only
includes records where the Description contains "Single" or "SFR" (Single Family Residence).
When it included the schools at multiple millions of dollars, the data got skewed.
