3bd 2 bath house 1200 sqft too small for rental?

[Corey Slaughter]

I found a 3 bed 2 bath house rental property that seems nice but when I went to tour it, the master bedroom and bathroom are a good dize but the other 2 bedrooms are quite small with one being very small (~8ft by 12ft is my guess). How much of a concern is this in general? Is this just something to factor in by assuming I will not get as much rent for it?
