How much is an extra bathroom worth?

[Alex Verdugo]

I'm looking through the MLS and find this duplex. Looks nice and in a decent B-class neighborhood. There has been some rehabbing, floors, walls, etc. throughout both units. Both sides have 2 beds but one side is one bath and the other has 2. The 2 bath has 70s style tile in each bathroom around the tub, shower, and sinks. The single bathroom unit has an updated bathroom. Other than the bathroom situation, both sides seem to be recently remodeled. The 2 baths are listed at $1000 rent and the single bath is $800. Also, the 2 bath is 1200 sqft and the single is 850sqft.

So how much is an extra bathroom worth?

 I'm sure that having a modern bath is nice but is having two slightly less updated baths really worth an extra $200?  (The shower in one of the bathrooms has the classic replaced tiles with a completely different color patchwork.)
