I guess I didn’t make myself clear.
The market rent for one’s particular unit incorporates all the factors you bring up. The market rent for an extra nice unit, or a better location, or an ocean view, etc. will naturally be higher. A unit with negatives would command a lower market rent.
Accordingly, one should never charge “above market rent”. Again, the hard part is “price discovery”–to objectively look at comps and find your proper rent.
