I recently purchased the middle unit in a three-stack which had an asking price higher than the bottom floor, but less than the top floor. I inquired with my buyer's agent why this was the case - particularly because I had a preference for the ground floor because it had fewer stairs. His answer at the time, which may or may not be broadly generalizable outside of my specific market (Boston area, USA) and obviously individual buyers' preferences vary wildly:
Yes, units higher up are able to command higher prices, all else held equal. The reasoning related to me by my agent boils down to:
- Units at higher elevation have larger viewsheds - the effect of this will depend on what there is to be seen, in my case there's an ocean view.
- Units lower down, especially at ground level, are more vulnerable to (and thus more prone to) various forms of intrusion - burglars can attack ground units through windows without needing special equipment.
- Basement units, in particular, suffer from light issues.
- Street noise is closer to (and thus louder for) ground level units.
