Assessment appeal for 1 Bay Avenue, Great Diamond Island
Portland
Summary
A Great Diamond Island seasonal cottage owner appealed his $620,600 tax assessment, asking the board to cut it to about $460,000 based on comparable island cottage sales and claims of unequal per-square-foot valuations. The board unanimously denied the appeal, meaning the assessment stands.

Impact analysis
The $620,600 assessment stays in place, so the owner's property tax bill won't shrink; a prior abatement already cut the value by $67,500.
The City's assessed valuation and the broader tax base are unchanged; other taxpayers avoid a shift from a reduced assessment.
The appellant pays taxes on the $620,600 assessment rather than the roughly $460,000 value he sought.
