Abel - I'm a realtor/investor active on Long Island, so this one caught my eye. A few thoughts from the buy side:
Levittown new construction at that exit price lives or dies on the school district line. Island Trees vs. Levittown SD moves the resale number meaningfully, so worth confirming which side of the line this lot falls on.
Corner lots in the Town of Hempstead can also get sticky with setbacks and curb-cut/egress rules, which eats into the buildable envelope. Worth verifying as-of-right zoning before locking in the program.
And for anyone running the math: with a ~$1.45M ARV against a $649k land ask, make sure your all-in - demo, permits, hard and soft costs, plus 12+ months of carry at today's rates - leaves real margin. Nassau County builds rarely come in fast.
Is this a teardown or a vacant lot, and are there approved plans/permits already in place?
