I was contracted to do a HUD REO property. During the inspection, there was a notice on the door from the city's Engineering and Building Department. I called and found out the subject was condemned the previous day by the city council and is now scheduled to be torn down. The client still wants an appraisal. However, they want me to appraise the property with the present effective date and as-is, as vacant land stating that the structure no longer holds value. I did some research there are a few closed sales that have sold that were torn down by the city a few months after their sales. I'd have to do some more research to find out if the purchaser knew they were condemned or not from the listing and/or selling agent, but there are similar condition sales on the market. I told them I'd be happy to do a vacant land appraisal with the hypothetical condition the structure was not there, but they don't want that. I'm probably missing something obvious, but condemnation is not an issue I'm familiar with. Any advice?
