I wou;d contact a Realtor local in that area. They can pull up the actual sold price of homes for 2005 in Neptune and give you the actual value of the homes. If you have any questions I can help you since Neptune is an area I work and live in. Denise Sherman-Pula Jack Green Realty 570-077-4250
Are u referring to the "current value" of homes sold in 2005? If so, according to Jeffrey Otteau, noted tri-state area appraiser, the decreases/increases in value in NJ from 2005 to date are as follows:
Take the sale price in 2005 and subtract/add his valuations.
If you have any questions, please do not hesitate to contact me direct @ francesca@Patriziore.com or 732.606.2931 as Neptune is within my selling area.
