📋 Note: Rent estimates based on current Staten Island/Brooklyn market data (March 2026). Actual rental income depends on unit condition, finishes, marketing, and local demand. Expenses are estimates — consult a CPA for tax implications. Plus One ADU grant eligibility requires HPD approval and rental to income-qualified tenants.
