Welcome to 111 Fuller Ave in Islip! This charming, five-bedroom, two-bathroom home situated in the Islip School District is brimming with potential.

Single-family homes in the Islip Union Free School District sold for a median of $716,000 (typically $630,000–$820,000) across 117 recorded sales between Oct 9, 2025 and Sep 29, 2026, up 6.1% on the 12 months before. This home's $629,999 list price sits in the entry single-family tier for the Islip Union Free School District.

ZIP 11751 has about 1.6 months of single family inventory — hot seller's market. Severe inventory shortage — homes sell fast and often draw multiple offers over asking, giving sellers maximum leverage.

At about $13,713 a year, this home's property tax is in line with the roughly $14,000 typical for Islip Union Free School District. Suffolk bills combine town, school and special-district levies, so two homes at the same price in neighboring districts can carry materially different taxes. Exemptions such as STAR, Senior or Veteran move the number as well — a new owner's bill is often not the same as the seller's.
