Methodology & Home Value Data Sources
How we calculate South Portland home values and property taxes: The home value, appreciation and rent figures on this page are Zillow Research index values (data through August 2026, page generated September 17, 2026). Market-speed, income and tax fields are Amortio planning estimates, not a live data feed; use the linked sources to verify current values.
- Typical home value, 1-year and 5-year change, and typical rent come from the Zillow Home Value Index (ZHVI) and Zillow Observed Rent Index (ZORI), Zillow Research, data through August 2026. ZHVI is the smoothed, seasonally adjusted typical value of mid-tier homes in the city (35th to 65th percentile), which behaves like a median but is not a median sale price. Population and income are rounded Amortio planning inputs; compare them with the US Census Bureau American Community Survey (ACS) and the FHFA House Price Index (HPI).
- Price per square foot, days on market, months of supply, list-to-sale ratio, homes sold, and foreclosure rate are modeled estimates, not MLS or listing-portal data.
- Payment math uses the 6.76% 30-year fixed national average from the Freddie Mac Primary Mortgage Market Survey (PMMS) for the week of September 10, 2026 (via FRED), not a personalized quote.
- Property tax rate is an estimated statewide effective rate applied to every city in the state; verify local rates with the county assessor or the Lincoln Institute of Land Policy property tax database.
- Cost of living index is an Amortio estimate (100 = national average); for official price data see BLS Consumer Price Index regional data.
