Hi Maureen. Good question. You are going to get some answers from realtors on here but I suggest you talk to an actual appraiser. I am a mortgage broker out of Bolingbrook and it is my experience that value questions ALWAYS ALWAYS ALWAYS are best posed to an appraiser. If you like, I can ask one of the appraisers I use to give a quick opinion on your question for you. Give me an email at firstname.lastname@example.org and I would be more than happy to do that for you. Good luck!
