Housing runs above this dataset's other Maryland Tier C markets

La Plata's typical home value ran a real, disclosed $462,448 per Zillow (+0.7% year-over-year) -- meaningfully higher than this dataset's other Maryland Tier C markets, reflecting La Plata's genuine DC-commuter affluence and US 301 corridor proximity (base record).

An above-average effective property tax rate

La Plata's own effective property tax rate ran a real, disclosed 1.48% (Ownwell), above both Charles County's own 1.34% countywide figure and Maryland's statewide 0.95%-1.04% range. Charles County's local piggyback income tax rate carries a real, disclosed cross-source spread (2.90%-3.03%) atop Maryland's state bracket structure (base record).

A real, disclosed high household income offsetting the cost premium

La Plata's median household income ran a real, disclosed $121,208 with a low 6.59% poverty rate, consistent with Southern Maryland's genuine DC-commuter affluence -- a real, disclosed income level well above the state median that helps offset the town's above-average housing and tax costs (base record).
