What they mean is the day-to-day "value" of having a roof over your head, in contrast to your ability to make money by selling.

If the area around you is improving substantially, then yes that day-to-day value could be improved by better local shops, maybe a closer office building, nicer parks, etc. Generally stuff like that does not happen quickly though, and really big changes like magically teleporting from boring middle of nowhere to a vibrant cultural downtown don't happen at all.
