It's hard to answer a question like that. In general, newer construction is made up of pretty crummy materials (lots of particleboard, OSB, etc...) that may or may not stand the abuse of rental use very well. On the other hand, there are things like appliances, and furnaces which may be more modern/reliable/etc...
In my limited experience, I have not found newish houses to command any kind of premium. In fact, there are a lot of people who like the older houses and will only buy those. 20-25 years old is old enough to not be considered new, but not old enough to really be part of the craftman/high quality styles of the past.
Of course, it depends on the house ultimately as not all houses from all years look the same.
