Looking to sell a duplex but having trouble determining value

[Penny Wilkinson]

How are appraisers approaching value on multi-family when there are extremely limited comps available?

I am considering selling a two-unit in West Texas, but only one duplex has been sold in town in the past eight years. I've talked to two local agents about possible price points to list at, but it almost seems like they are pulling numbers out of a hat. I'm curious what others have run into when comps are very limited.  Rents are high in this town and I think folks just don't sell their multi-family units very often.
