Market Analysis: 11722 Central Islip

Not every below-median market is a bargain. Central Islip's 11722 ZIP comes in at signals that favor experienced operators who can absorb the risk $579K pricing implies.

For an experienced owner, 11722 can be a worth a close look for hunting ground — but the discount at $579K reflects genuine risk that outside investors often underestimate.

ZIP 11722's metrics run below Suffolk County's averages on price growth and tenant stability. Investors who ignore that regional gap tend to relearn it the hard way.

Resident income in 11722 sits below the county median. That reality colors rent collection, vacancy, and reinvestment math in ways that outside investors often underestimate.

The 11722 ZIP fits a narrow investor profile — hands-on, patient, and willing to accept that the cap rate on paper is not the cap rate in reality.

Negative Leverage — IRR / Tax Play Cap Rate: 4.2%  |  30yr Rate: 6.8%
Leverage reduces cash returns at current rates.

The current 30-yr mortgage rate (6.8%) exceeds the estimated cap rate (4.2%). Financing reduces your cash-on-cash return below the cap rate. Markets like this may still make sense as IRR plays — factoring in appreciation, depreciation, and a future refinance when rates drop.

About Repit School Scores

Traditional school ratings rely heavily on standardized test scores, which often reflect family income more than school quality. Repit takes a different approach.

We evaluate schools based on factors that research shows actually impact educational outcomes:

  • Class Size — Smaller classes mean more individual attention
  • School Funding — Resources available for programs, staff, and facilities
  • Community Factors — Neighborhood characteristics that influence student success
  • School Environment — Size, type, and structure

Scores are updated annually using federal education data.
