Looking for reputable source for Fair Market Value
I'm needing to establish the fair market value for a house I have on my property. My realtor states he can't do this as it was moved onto my land which already had a house on it, and the house in question has no land allocated with it. Other realtors aren't willing to assist me because I'm already working with a realtor.
Are realtors the only individuals who can establish a fair market value, or would I have another option? I'm willing to pay for the service but have no idea who else to ask.
thanks!
