Tax accessed vs market price

[Mark Gruetzmacher]

What have most people seen when it comes to the tax accessed value of a property vs what the market is or what the selling price is. Being new at it I guess I always assumed that the tax accessed is usually a little lower but not too much or in some cases tax accessed is higher.

I guess I ask because I came across a guy selling thing older duplex. I talked with him and his rents are about 1300 combined and he was asking something like $135K. Now he told me the address and I jumped on the county's site and looked up the property and the tax accessed is only like 68K, the last 3 years it is all in the 60's. He bought the property for I think 124K in 2008. All numbers aside, when the tax accessed is half what the selling price is sure seems weird. I am not considering it at all but wondered if that is normal in the business?
