it's a 5 acre parcel. We've been listed way over price (at the sellers direction) for almost a year. All of the things you mention are why I'm struggling with this. We have a buyer, that the space is valuable to...but they haven't presented an offer yet. Now the seller wants to know what their current market value is in anticipation of that offer. I have a CMA almost finished, but the closest comp has a pole barn, not living space. I think it's more valuable than a pole barn...but, by how much? In the past, I've given the seller a suggested list price, which is not the same as a market value...I'm trying to be as precise as possible.
