Where is this property located? On a double yellow line road like Old Short Hills Rd or on a quiet street? The exact neighborhood and cost of homes surrounding the property make a huge difference in property value.
My guestimate based on the information you provided is anywhere from $1.7M - $2.7M (quite the range, but I've seen this scenario happen at Deerfield at each price point).
Please feel free to reach out directly if you would like more specific information.
I appreciate your question, and I sincerely hope you have a quality agent directing you appropriately in your situation. If not, you are certainly welcome to email me directly at Melanie@RealShortHills.com and I would be happy to assist. The real answer to your question is not easy to just throw your way w/o understanding many of the homes details as mentioned in other responses. Important variables for me, would definitely be to find out who was the home built by and who was the architect. As a home owner in town and representative of an Architect/ Builder I can honestly say that will make a huge difference in the quality and price of the home. Another important question would be, was it New Construction five years ago? If so, it should have 5 years left on a home warranty. If not, than only parts of the home may be "New". I am happy to discuss this further, and even happier to share my two New Construction listings in town with you! Go to: http://www.realshorthills.com/listings/new-construction/. Wishing you good luck!
Typically in Deerfield, you'll have a larger lot than 0.5.
Everyone wants what you're looking for, so you will pay a premium.
Deerfield is full of mid-1970s nasty split-levels, etc., so if you want to buy one for $1.1M-$1.6M and knock it down or rehab it, that's possible, but to get something finished, you're at $2.5M+
