CAP RATE OF 8%

I just saw a listing on our MLS with a cap rate of 8%. Now I am sure that pretty much everyone that might be reading this blog knows what they are getting for their money in cd's and t bonds etc. So why is this listing still on the market? If the owner is correct and this is truly giving a cap rate of 8% where are the investors. The thing with real estate is, everyone needs to live somewhere just like everyone produces garbage and everyone leaves this earth at sometime. That is why those respective businesses are usually good to get into. So why has this listing, in a great location not sold. You tell me!
