Can someone explain the price comparison of two duplexes?

[Joseph Fernandez]

I was browsing through Zillows website in search for duplexes. I found two duplexes which the price difference between the two is a vast amount but in a confusing way (Confusing for me). The cheaper duplex has a more appealing view in a well kept neighborhood than the more expensive one. The more expensive one seems to me would be worth way less.

(NOTE: I'm currently learning real estate, so I went on Zillows to learn the prices of duplexes in my area)

Here is the links for the duplexes:

The Ugly one : Duplex - $279,000

The Attractive one: Duplex - $135,000

Yeah, it definitely could. So looking again, I'm pretty sure the cheaper one is only one side of the duplex, which is currently vacant, where as the more expensive one is the whole duplex, and is rented out completely. 

Two units doubles the revenue, and logically, could double the price. Things get a bit different once you get past 4 units though.
