How Do Comparable Home Sales Work on Long Island?

Start With Comparable Sales
Use recent, relevant sales and adjust for meaningful differences in location, size, lot, condition, renovations, garage, basement and taxes.
Evaluate the Exact Location
School district, village, waterfront access, flood considerations, major roads and micro-neighborhood differences can change demand.
Consider Condition and Renovation Level
Roof, electrical, plumbing, heating, water damage, mold, code issues and interior finish can affect the buyer pool.
Use Price Per Square Foot Carefully
It can help describe a market but should not replace a complete property comparison.
Understand Online Estimates
Automated values may not see interior condition, renovation quality, unpermitted work or a specific view and location advantage.
Value an As-Is Property Separately
Renovated sales can indicate potential after-repair value, but repair cost, holding time and risk affect present value.
