Local Insight

This 1948 duplex in an AE flood zone is priced at $430/sqft, which is reasonable for the area, but you'll need to factor in flood insurance costs and elevation requirements that could significantly impact your ongoing expenses and any future refinancing. The 0.16-acre lot is tight for a two-unit property, so rental upside or renovation potential will depend heavily on what the actual unit layouts allow—worth scrutinizing whether each side has income-generating capacity. Given the age and flood designation, a thorough inspection and honest conversation with an insurance agent should come before any offer.
