The houses in 10303
Ask what a house costs on Staten Island and 10303 gives the lowest answer. The median house sale here in 2025 was $560,000, the lowest of any island ZIP, against $748,207 borough-wide. Across 147 recorded sales in Mariners Harbor, Graniteville, Arlington and Port Ivory, half fell between $480,825 and $647,500.
The houses are small, and newer than the island's typical house. The median one had 1,344 square feet, on a 2,832 square foot lot, the smallest medians on the island for both.

That shows in the building classes. Attached or semi-detached one family houses were the most common sale, 58 of them, then two-story detached houses (36) and frame two family houses (30). One family houses made up 70% of sales, two family 29%. A typical one family sold for $545,000 with 1,280 square feet; a typical two family for $620,000 with 1,770. Per square foot the median came to $412.
